Oracle ATG – Endeca Integration
Introduction The ATG-Endeca integration enables customers of Oracle ATG Web Commerce and Oracle Endeca Commerce to index ATG product catalog data in Endeca MDEX engines, where it can then be queried and the results can be displayed on commerce sites. This document describes how to configure ATG indexing and querying components to work with Oracle Endeca Commerce.
Page 3
Oracle ATG – Endeca Integration
Installation Requirements The ATG-Endeca integration requires that Oracle ATG Web Commerce and Oracle Endeca Commerce software (including either Oracle Endeca Guided Search or Oracle Endeca Experience Manager), be installed in your environment. We also suggest that you initially install ATG Oracle Web Commerce Reference Store, so that you have an application and data to work with as you familiarize yourself with the integration.
Page 4
Oracle ATG – Endeca Integration
Creating the Endeca Applications To create an Endeca application to integrate with ATG, use the Endeca deployment template designed to work with product catalog data. This deployment template has a script that creates various Endeca CAS (Content Acquisition System) record stores that the ATG-Endeca integration writes to. The naming convention for these record stores is. application-name_language-code_record-store-type
So for an application named ATGen that indexes ATG product catalog data in English, the record stores are.
ATGen_en_data-- Holds data records representing SKUs or products. ATGen_en_dimvals-- Holds dimension value records generated from the category hierarchy and from the hierarchy of repository item types. ATGen_en_schema-- Holds records representing property and dimension definitions generated from the set of ATG properties being indexed.
Number of Endeca Applications to Create For each ATG Server instance, you must have at least one unique Endeca application and corresponding MDEX. For example, if you are configuring a ATG Content istration server and a production server, you will need a minimum of two Endeca applications and two MDEX engines. If your product catalog has data in multiple languages, the number of Endeca applications you have per server depends on your approach to indexing these languages, as described below. One Language per MDEX In this configuration, you have one MDEX for each language for each server. For example, if you have three languages i.e. English, German, and Spanish and you have two servers i.e. Content istration and Production then you must have six Endeca applications. Content istration/English Content istration/German Content istration/Spanish Production/English Production/German Production/Spanish Each ATG server should use a different Endeca base application name, which by default is used for all of the applications associated with that server. For example, you could set the base application name for the Content istration server to ATGCA, and set the base application name for the Production server to ATGProd. By default, the names of the applications for the different languages on a given server are distinguished by adding the two-letter code for the language to the base application name.
Page 5
Oracle ATG – Endeca Integration for example, the names of the Content istration-related Endeca applications would be ATGCAen, ATGCAde, and ATGCAes, and the names of the Production-related Endeca applications would be ATGProden, ATGProdde, and ATGProdes. All Languages in a Single MDEX If you plan to have all languages indexed in a single MDEX, you only need to create one Endeca application for each ATG server instance. Each ATG server should use a different Endeca base application name; for example, you could set the base application name for the Content istration server to ATGCA, and set the base application name for the Production server to ATGProd. By default, the name of the application is the base application name plus the two-letter language code for the default language for the application; for example, ATGCAen and ATGProden. Be sure to specify the default language (in this case, en) in the /atg/endeca/ApplicationConfiguration component’s defaultLanguageForApplications property for each ATG server instance. defaultLanguageForApplications=en
Provisioning the Endeca Applications For each Endeca application you create, you must provision it by running the initialize_services.sh|bat script found in the application’s /control directory. Therefore, if you have six Endeca applications, you must invoke this script six times. The initialize_services.sh script is found in the following location /endeca/Endecaapplication-directory/your-application/control/.

Configuring the ATG Server Instances in CIM You must configure your ATG server instances for an ATG-Endeca integration environment using the Configuration and Installation Manager (CIM). ATG Product Selection To configure your server instances to use the ATG-Endeca integration, select ATG-Endeca Integration and Oracle ATG Web Commerce in the Product Selection menu. If your installation includes Oracle ATG Commerce Reference Store, you can select Oracle ATG Commerce Reference Store instead. Your server installations will automatically include ATG Commerce and the ATG-Endeca integration, because Commerce Reference Store requires them. ATG Server Instance Creation During your ATG server instance configuration, you must provide information about your Endeca environment so that the ATG server instance can communicate with Oracle Endeca Commerce. The required settings and their defaults are provided in the table below.
After your ATG server instances are configured in CIM, start them in preparation for indexing.

Configuring the ApplicationConfiguration Component The atg.endeca.configuration.ApplicationConfiguration class provides a central place for configuring various global settings, including language configuration options and application naming. The ATG-Endeca integration includes a component of this class, /atg/endeca/ApplicationConfiguration. The following are key properties of this component.
a. locales - An array of the locales to generate records for.
b. defaultLanguageForApplications - The two-letter code for the default language for the application. This should be set only if there is a single MDEX for all languages being indexed. By default the value of this property is null.
c. baseApplicationName - The base string used in constructing the Endeca EAC application names. The default setting is ATG. You can override the default when you use CIM to configure your ATG environment. d. keyToApplicationName - A map of application keys to application names. You can use this property to override the default application naming convention discussed in Determining the Number of Endeca Applications to Create. For example, if an environment s English, Spanish, and German, and there is a separate Endeca application for each language, you can specify the application names like this. keyToApplicationName=\ en=MyEnglishApp,\ es=MySpanishApp,\ de=MyGermanApp The application keys in this case are the two-letter language codes. An array of the keys is stored in the read-only applicationKeys property. If there is a single application, the key is default. You can specify the application name like this. keyToApplicationName=\ default=MyApp defaultApplicationKey
Page 8
Oracle ATG – Endeca Integration The key of the application to use if the current application cannot be determined. If there is a separate application for each language, the first key listed in the applicationKeys property is the default, unless you change the default by explicitly setting the defaultApplicationKey property to a different key. If there is only one Endeca application, you do not need to set this property; it will automatically be set to default. e. workbenchHostName - The fully qualified host name, including the domain, of the machine running the Endeca Workbench. You can specify this setting when you use CIM to configure your ATG environment. f. workbenchPort - The port number for accessing the Endeca Workbench. The default setting is 8006. You can override this default when you use CIM to configure your ATG environment.

Starting the Indexing Process The indexing process can be started in two ways i.e. automatically as part of running a full deployment through ATG Content istration or manually using the Dynamo Server . Increasing the Transaction Timeout and Datasource Connection Pool Values Depending on your application server, you may need to increase the transaction timeout and datasource connection pool settings in order for indexing to run successfully. Increasing the Transaction Timeout If indexing is not successful, it may be related to the transaction timeout setting in your application server. Oracle ATG recommends setting a transaction timeout of 300 seconds or greater. All ed application servers time out long-running transactions by marking the active transaction as rolled back which can result in problems when indexing. If your indexing process fails, try increasing the transaction timeout setting. Increasing the Datasource Connection Pool Oracle ATG recommends setting the data source connection pool maximum capacity to 30 or greater for all of your data sources. Indexing As Part of a Deployment You can configure your environment so that when you run a deployment in Content istration, indexing is automatically started after the deployment is finished. a. To make this automatic triggering occur, add the following three components and their configuration to the localconfig layer for your Content istration server. /atg/commerce/endeca/index/CategoryToDimensionOutputConfig b.
Specify the following property for the CategoryToDimensionOutputConfig component:
targetName=Production c. Specify the following property for the /atg/commerce/search/ProductCataputConfig component. targetName=Production d. Specify the following properties for the /atg/search/SynchronizationInvoker component. host=atg-production-server-host rmi=8860
Page 10
Oracle ATG – Endeca Integration Manually Starting the Indexing Process a. To manually start an indexing job, to ATG Dynamo istration for the appropriate ATG server instance. b. Navigate to/atg/commerce/endeca/index/ProductCatalogSimpleIndexing component. c. From here, click Baseline Index to start a baseline index, or Partial Index to start a partial update. Monitoring the Indexing Process Regardless of how an indexing process has been started, you can monitor its progress in ATG Dynamo istration by viewing the/atg/commerce/endeca/index/ProductCatalogSimpleIndexing component. Each phase of the indexing process is listed in the table under Indexing Job Status. To dynamically refresh the window, enable the Auto Refresh option below the table.
Page 11
Oracle ATG – Endeca Integration
Viewing the Indexed Data You can view the indexed data residing in your MDEX engines using Oracle Endeca’s JSP Reference Implementation. a. In a browser, navigate to http://host:port/endeca_jspref, where host:port refers to the name and port of the server hosting the Endeca Tools and Frameworks installation, for example: http://localhost:8006/endeca_jspref b. Click the ENDECA-JSP Reference Implementation link. c. Enter an MDEX host and port, and then click Go.

ATG Modules The main ATG-Endeca integration modules are.
Note that when you assemble an application that includes any of the modules listed in the table above, the DAF.Search.Base and DAF.Search.Index modules are automatically included in the EAR file as well. These modules contain core repository indexing classes that are subclassed in the Endeca-specific modules. In addition, some of the Endeca-specific modules pull in classes from other search modules through the ATG-Class-Path entries in their manifest files.

Oracle ATG – Endeca Integration
Overview of Indexing To make your product catalog available for searching, the Oracle ATG Web Commerce platform must transform the data into the appropriate format, and then submit this data to Oracle Endeca Commerce for indexing. The process of indexing ATG product catalog data in Oracle Endeca Commerce works like this. 1. ATG components transform the catalog repository data into Endeca records that represent Endeca properties, dimensions, and schema. a. Properties of ATG products and SKUs are used to create Endeca properties and nonhierarchical dimensions. b. The ATG category hierarchy is used to create a hierarchical category dimension in Oracle Endeca Commerce. The hierarchy of repository item types in the product catalog is used to create another hierarchical Endeca dimension. c. An Endeca schema is created by examining the set of ATG properties to be indexed. 2. The generated records are submitted to Endeca CAS data, dimension value, and schema record stores. 3. The Endeca EAC is invoked, which creates Forge processes that process the record stores and invoke indexing.
Page 14
Oracle ATG – Endeca Integration
Indexable Classes The ATG platform includes an interface, atg.endeca.index.Indexable, that is implemented by the classes responsible for creating Endeca records. Key classes that implement this interface include.
atg.endeca.index.EndecaIndexingOutputConfig atg.commerce.endeca.index.dimension.CategoryTreeService atg.endeca.index.dimension.RepositoryTypeHierarchyExporter atg.endeca.index.schema.SchemaExporter
EndecaIndexingOutputConfig Class The main class used to specify how to transform repository items into records is atg.endeca.index.EndecaIndexingOutputConfig. The ATG-Endeca integration includes two components of this class.
/atg/commerce/search/ProductCataputConfig /atg/commerce/endeca/index/CategoryToDimensionOutputConfig
Each EndecaIndexingOutputConfig component has a number of properties, as well as an XML definition file, for configuring how repository data should be transformed to create Endeca records. ProductCataputConfig Component The ProductCataputConfig component specifies how to create Endeca data records that represent items in the ATG product catalog. Each record represents either one product or one SKU (depending on whether you use product-based or SKU-based indexing), and contains the values of the ATG properties to be included in the index. In addition, each record includes properties of parent and child items. For example, a record that represents a product includes information about its parent category’s properties, as well as information about the properties of its child SKUs. This makes it possible to search category and SKU properties as well as product properties when searching for products in the catalog. Multi-value properties are given names without array subscripts. For example, a product repository item might have multiple child sku items, each with a different value for the color property. In the output record there will be multiple entries for sku.color. The following is an XML representation of a portion of a Commerce Reference Store record. Note that the actual records submitted to the CAS data record store are in a binary object format, not XML.
Page 15
Oracle ATG – Endeca Integration
CategoryToDimensionOutputConfig Component The CategoryToDimensionOutputConfig component specifies how to create Endeca dimension value records that represent categories from the ATG product catalog. This category dimension makes it possible to use Oracle Endeca Commerce to navigate the categories of a catalog. CategoryToDimensionOutputConfig creates dimension values using a special representation of the category hierarchy that is generated by the/atg/commerce/endeca/index component. The following example shows an XML representation of a portion of a category dimension value record generated by CategoryToDimensionOutputConfig.
Page 16
Oracle ATG – Endeca Integration
CategoryTreeService Class The ATG-Endeca integration uses the category hierarchy in the ATG product catalog to construct a category dimension in Oracle Endeca Commerce. In some cases, the hierarchy cannot be translated directly, because ATG’s catalog hierarchy s categories with multiple parent categories, while Endeca requires each dimension value to have a single parent. For example, suppose you have the following category structure in your product catalog.
Page 17
Oracle ATG – Endeca Integration
To deal with this structure, the ATG-Endeca integration creates two different records for the Men’s Shoes dimension value, one for each path to this category in the catalog hierarchy. These paths are computed by the atg.commerce.endeca.index.dimension.CategoryTreeService class. The ATG-Endeca integration includes a component of this class, /atg/commerce/endeca/index/CategoryTreeService. This component, which is run in the first phase of the indexing process, creates data structures in memory that represent all possible paths to each category in the product catalog. A category can have multiple parents, and those parents and their ancestors can each have multiple parents, so there can be any number of unique paths to an individual category. The CategoryToDimensionOutputConfig component then uses the /atg/commerce/endeca/index/CategoryPathVariantProducer component to create multiple records for each category, one for each path computed by CategoryTreeService. For each path, the corresponding record uses the pathname as the value of its dimval.spec property; this makes it possible to differentiate records that represent different paths to the same category. In the example above, two records are created for the Men’s Shoes category. The dimval.spec entry in one of the records might be.
The dimval.spec entry in the other record for the category might be.
Page 18
Oracle ATG – Endeca Integration RepositoryTypeHierarchyExporter Class The atg.endeca.index.dimension.RepositoryTypeHierarchyExporter class creates Endeca dimension value records from the hierarchy of repository item types in the product catalog, and submits those records to the CAS dimension values record store. This dimension is not typically displayed on a site, but can be used in determining which other dimensions to display. For example, Commerce Reference Store has a furniture-sku subtype that includes a woodFinish property that can be used as an Endeca dimension. A site can include logic to detect whether the items returned from a search are of type furniture-sku, and display the woodFinish dimension if they are. The ATG-Endeca integration includes a component of class RepositoryTypeHierarchyExporter, /atg/commerce/endeca/index/RepositoryTypeDimensionExporter, that is configured to work with the ProductCataputConfig component. The RepositoryTypeDimensionExporter component outputs dimension value records for the entire repository item types referred to in the ProductCataputConfig definition file, as well as the ancestors and descendants of those item types. RepositoryTypeDimensionExporter does not create records for any item types that are not part of the hierarchy mentioned in the definition file. The following example shows a record produced by the RepositoryTypeDimensionExporter component for the product item type.
SchemaExporter Class The atg.endeca.index.schema.SchemaExporter class is responsible for generating schema records and submitting them to the Endeca schema record store. The /atg/commerce/endeca/index/SchemaExporter component of this class examines the ProductCataputConfig definition file and generates a schema record for each ATG property that is output. The schema record indicates whether the ATG property should be treated as a property or a dimension by Oracle Endeca Commerce, whether it should be searchable, and the data type of the property or dimension.
Page 19
Oracle ATG – Endeca Integration
For example, the following is an XML representation of a schema record for the product.description property, which identifies it as a searchable Endeca property whose data type is string.
Page 20
Oracle ATG – Endeca Integration
Submitting the Records Once the records have been generated, they are submitted to the appropriate CAS record stores by components of classatg.endeca.index.RecordStoreDocumentSubmitter. The ATG platform includes three components of this class, each of which is configured to submit to a different record store.
/atg/endeca/index/DataDocumentSubmitter -- Submits records to the data record store (for example, ATGen_en_data). /atg/endeca/index/DimensionDocumentSubmitter -- Submits records to the dimension values record store (for example, ATGen_en_dimvals). /atg/endeca/index/SchemaDocumentSubmitter -- Submits records to the schema record store (for example, ATGen_en_schema).
The EndecaIndexingOutputConfig, RepositoryTypeHierarchyExporter, and SchemaExporter classes each have a documentSubmitter property that is used to specify a document submitter component to use to submit records to the appropriate CAS record store. The following table shows default values of the documentSubmitter property of each component of these classes.
Page 21
Oracle ATG – Endeca Integration
Managing the Process The atg.endeca.index..SimpleIndexing class provides a mechanism for managing the process of generating records, submitting them to Endeca, and invoking indexing. The ATG-Endeca integration includes a component of this class /atg/commerce/endeca/index/ProductCatalogSimpleIndexing. The page for this component in the Component Browser of the ATG Dynamo Server presents a simple interface for controlling and monitoring the process.
After the records are generated and submitted to Oracle Endeca Commerce, ProductCatalogSimpleIndexing calls the /atg/commerce/endeca/index/EndecaScriptService component (of class atg.endeca.eacclient.ScriptIndexable). This component is responsible for invoking Endeca Application Controller (EAC) scripts that trigger indexing. The UI provides buttons for initiating an Endeca baseline index or a partial update. Note that even if you click Partial Index, a baseline update may be invoked if the changes since the last baseline update necessitate it.
Page 22
Oracle ATG – Endeca Integration
Configuring the Indexing Components Here we discuss about the indexing-related Nucleus components in the ATG-Endeca integration, what they do, how they are configured, and how you can modify them to alter various aspects of indexing.
Page 23
Oracle ATG – Endeca Integration
IndexingApplicationConfiguration Component The atg.endeca.index.configuration.IndexingApplicationConfiguration class provides a central place for configuring various indexing settings. The ATG-Endeca integration includes a component of this class, /atg/endeca/index/IndexingApplicationConfiguration. This component is configured by default with typical settings, but you can override these defaults when you use CIM to configure your ATG environment.
a. CASHostName = the hostname of the machine running CAS. The default setting is. CASHostName=localhost b. CASPort= the port number of the machine running CAS. The default setting is. CASPort=8500 c. eacHostName = the hostname of the EAC server. The default setting is. eacHost=localhost d. eaort = the port used by the EAC server. The default setting is. eaort=8888 e. applicationConfiguration = the component of class atg.endeca.configuration.ApplicationConfiguration used to configure global settings for the integration. The default setting is. applicationConfiguration=/atg/endeca/ApplicationConfiguration
Page 24
Oracle ATG – Endeca Integration
EndecaIndexingOutputConfig Components The atg.endeca.index.EndecaIndexingOutputConfig class has a number of properties that configure various aspects of the record creation and submission process. a. definitionFile = The full Nucleus pathname of the XML indexing definition file that specifies the repository item types and properties to include in the Endeca records. For the /atg/commerce/search/ProductCataputConfig component, this property is set as follows. definitionFile=/atg/commerce/endeca/index/product-sku-output-config.xml For /atg/commerce/endeca/index/CategoryToDimensionOutputConfig, this property is set as follows. definitionFile=/atg/commerce/endeca/index/category-dim-output-config.xml b. repository = The full Nucleus pathname of the repository that the definition file applies to. For both the ProductCataputConfig and CategoryToDimensionOutputConfig, this property is set to the product catalog repository. repository=/atg/commerce/catalog/ProductCatalog
Note that in an ATG Content istration environment, the repository should not be set to a versioned repository. Instead, it should be set to the corresponding un-versioned target repository. For example, an EndecaIndexingOutputConfig component for a product cata an ATG Content istration environment could be set to. repository=/atg/commerce/catalog/ProductCatalog_production c. repositoryItemGroup = A component of a class that implements the atg.repository.RepositoryItemGroup interface. This interface defines a logical grouping of repository items. Items that are not included in this logical grouping are excluded from the index. For the CategoryToDimensionOutputConfig component, this property is set by default to null (so no items are excluded). For the ProductCataputConfig component, repositoryItemGroup property is set by default to. repositoryItemGroup=/atg/commerce/search/IndexedItemsGroup The IndexedItemsGroup component uses this targeting rule set to select only products that have an ancestor catalog:
Page 25
Oracle ATG – Endeca Integration
This rule set ensures that the index does not include products that are not part of the catalog hierarchy. d. documentSubmitter = The component (typically of class atg.endeca.index.RecordStoreDocumentSubmitter) to use to submit records to the appropriate CAS record store. For the ProductCataputConfig component, this property is set as follows. documentSubmitter=/atg/endeca/index/DataDocumentSubmitter
For the CategoryToDimensionOutputConfig component: documentSubmitter=/atg/endeca/index/DimensionDocumentSubmitter e. bulkLoader = A Nucleus component of class atg.endeca.index.RecordStoreBulkLoaderImpl. This is typically set to /atg/search/repository/BulkLoader. Any number of EndecaIndexingOutputConfig components can use the same bulk loader.

Oracle ATG – Endeca Integration
ProductCatalogSimpleIndexing The /atg/commerce/endeca/index/ProductCatalogSimpleIndexing component (of class atg.endeca.index..SimpleIndexing) manages the process of generating records, submitting them to Oracle Endeca Commerce, and invoking indexing. The page for this component in the Component Browser of the ATG Dynamo Server presents a simple interface for controlling and monitoring the process. The SimpleIndexing class defines indexing in of an indexing job, which is made of up indexing phases, which in turn contain indexing tasks. Each indexing task is responsible for executing an individual Indexable component. Tasks within a phase may run in sequence or in parallel, but in either case all tasks in a phase must complete before the next phase can begin. By default, the ProductCatalogSimpleIndexing defines three phases. 1. PreIndexing -- Runs /atg/commerce/endeca/index/CategoryTreeService.
2. RepositoryExport -- Runs these components in parallel: /atg/commerce/endeca/index/SchemaExporter /atg/commerce/endeca/index/CategoryToDimensionOutputConfig /atg/commerce/endeca/index/RepositoryTypeDimensionExporter /atg/commerce/search/ProductCataputConfig 3. EndecaIndexing -- Runs /atg/commerce/endeca/index/EndecaScriptService, which invokes Endeca indexing scripts. You can invoke indexing jobs manually through the ProductCatalogSimpleIndexing interface. In addition, the SimpleIndexing class implements the atg.service.scheduler.Schedulable interface, so it is also possible to configure the ProductCatalogSimpleIndexing component to invoke indexing jobs automatically on a specified schedule. Note: to know about more properties then refer this link

Oracle ATG – Endeca Integration
Specifying Properties for Indexing This section describes how to specify various properties of catalog items for inclusion in the Endeca MDEX, and options for how these properties should be handled. Specifying Multi-Value Properties In most cases, you specify a multi-value property, such as an array or Collection, using the property element, just as you specify a single-value property. In the following example, the features property stores an array of Strings.
Notice that features is specified in the same way as creationDate, brand, and displayName, which are all single-value properties. The output will include a separate entry for each value in the features array. If a property is an array or Collection of repository items, you specify it using the item element, and set the is-multi attribute to true. For example, in a product catalog, a product item will typically have a multi-valued childSKUs property whose values are the various SKUs for the product. You might specify the property like this.
Specifying Map Properties To specify a Map property, you use the item element, set the is-multi attribute to true, and use the mapiteration-type attribute to specify how to output the Map entries. If the Map values are primitives or Strings, set map-iteration-type to wildcard, as in this example.
In the output, the Map keys are treated as subproperties of the Map property, and the Map values are treated as the values of these subproperties. All of the Map entries are included in the output. So, for example, the output from the definition file entry shown above might look like this.
Page 28
Oracle ATG – Endeca Integration
If you want to output only a subset of the Map entries, explicitly specify the keys to include, rather than using the wildcard character (*). For example.
Maps of Repository Items If the Map values are repository items, set map-iteration-type to values, and specify the properties of the repository item that you want to output. For example, suppose you want to index a productInfos Map property whose keys are product IDs and whose values are productInfo items.
The output will include displayName and size tags for each productInfo item in the Map. In this case, the Map keys are ignored, the properties of the repository items are treated as subproperties of the Map property, and the values of the items are treated as the values of the subproperties. The output looks like this.
Page 29
Oracle ATG – Endeca Integration Specifying Properties of Item Subtypes A repository item type can have subtypes that include additional properties that are not part of the base item type. This feature is commonly used in the Oracle ATG Web Commerce catalog for the SKU item type. A SKU subtype might add properties that are specific to certain SKUs but which are not relevant for other SKUs. When you list properties to index, you can use the subtype attribute of the property element to specify properties that are unique to a specific item subtype. For example, suppose you have a furniture-sku subtype that adds properties specific to furniture SKUs. You might specify your SKU properties like this.
This specifies that the description and color properties should be included in the output for all SKUs, but for SKUs whose subtype is furniture-sku, the woodFinish property should also be included. The item element also has a subtype attribute for specifying a subtype-specific property whose value is a repository item. If woodFinish is a repository item, the example above would look something like this.
Specifying a Default Property Value You may find it useful to specify a default value for certain indexed properties. For example, suppose you are indexing address data, and for some addresses no value appears in the repository for the city property. In these cases, you could set the property value in the index to be “city unknown.” A could then search for this phrase and return the addresses whose city property is null. To set a default value, you use the default-value attribute of the property element. For example.
Page 30
Oracle ATG – Endeca Integration Specifying Non-Repository Properties When you index a repository, you can include in the index additional properties that are not part of the repository itself. For example, you might want to include a creationDate property to record the current time when a record is created. The value for this property could be generated by a custom property accessor that invokes the Java Date class. To specify a property like this, use the is-non-repository-property attribute of the property element. This attribute indicates that the property is not actually stored in the repository, and prevents warnings from being thrown when the IndexingOutputConfig component starts up. Note that you must also specify a custom property accessor that is responsible for obtaining the property values.
If no actual property accessor is needed, set the property-accessor attribute to null. For example, you might do this if you have a default value that you always want to use for the property.
Suppressing Properties The output record automatically includes certain standard JavaBean properties of the RepositoryItem object. These properties provide information that identifies the repository items represented in the record, and they are indicated in the definition file by a dollar-sign ($) prefix: $repositoryId, $repository.repositoryName, and $itemDescriptor.itemDescriptorName. (The dollar-signs are removed by default in the output records, because Endeca property names cannot include them.) You may want to return these properties in search results, to enable accessing the indexed repository and repository items in page code. Typically you would do this for the document-level item type. For other item types, you may not need these properties. If you do not need these properties, it is a good idea to exclude them from the index, as they may significantly increase the size of the index. To suppress one of these properties, specify the property in the indexing definition file with the suppress attribute. For example.
Renaming an Output Property By default, the name of a property in an output record is based on its name in the repository, with modifications applied based on the values of the replaceWithTypePrefixes, prefixReplacementMap, and suffixReplacementMap properties of the EndecaIndexingOutputConfig component.
Page 31
Oracle ATG – Endeca Integration You can instead specify the output property name by using the output-name attribute of the property element. For example.

Introduction The ATG-Endeca integration enables customers of Oracle ATG Web Commerce and Oracle Endeca Commerce to index ATG product catalog data in Endeca MDEX engines, where it can then be queried and the results can be displayed on commerce sites. This document describes how to configure ATG indexing and querying components to work with Oracle Endeca Commerce.
Page 3
Oracle ATG – Endeca Integration
Installation Requirements The ATG-Endeca integration requires that Oracle ATG Web Commerce and Oracle Endeca Commerce software (including either Oracle Endeca Guided Search or Oracle Endeca Experience Manager), be installed in your environment. We also suggest that you initially install ATG Oracle Web Commerce Reference Store, so that you have an application and data to work with as you familiarize yourself with the integration.
Page 4
Oracle ATG – Endeca Integration
Creating the Endeca Applications To create an Endeca application to integrate with ATG, use the Endeca deployment template designed to work with product catalog data. This deployment template has a script that creates various Endeca CAS (Content Acquisition System) record stores that the ATG-Endeca integration writes to. The naming convention for these record stores is. application-name_language-code_record-store-type
So for an application named ATGen that indexes ATG product catalog data in English, the record stores are.
ATGen_en_data-- Holds data records representing SKUs or products. ATGen_en_dimvals-- Holds dimension value records generated from the category hierarchy and from the hierarchy of repository item types. ATGen_en_schema-- Holds records representing property and dimension definitions generated from the set of ATG properties being indexed.
Number of Endeca Applications to Create For each ATG Server instance, you must have at least one unique Endeca application and corresponding MDEX. For example, if you are configuring a ATG Content istration server and a production server, you will need a minimum of two Endeca applications and two MDEX engines. If your product catalog has data in multiple languages, the number of Endeca applications you have per server depends on your approach to indexing these languages, as described below. One Language per MDEX In this configuration, you have one MDEX for each language for each server. For example, if you have three languages i.e. English, German, and Spanish and you have two servers i.e. Content istration and Production then you must have six Endeca applications. Content istration/English Content istration/German Content istration/Spanish Production/English Production/German Production/Spanish Each ATG server should use a different Endeca base application name, which by default is used for all of the applications associated with that server. For example, you could set the base application name for the Content istration server to ATGCA, and set the base application name for the Production server to ATGProd. By default, the names of the applications for the different languages on a given server are distinguished by adding the two-letter code for the language to the base application name.
Page 5
Oracle ATG – Endeca Integration for example, the names of the Content istration-related Endeca applications would be ATGCAen, ATGCAde, and ATGCAes, and the names of the Production-related Endeca applications would be ATGProden, ATGProdde, and ATGProdes. All Languages in a Single MDEX If you plan to have all languages indexed in a single MDEX, you only need to create one Endeca application for each ATG server instance. Each ATG server should use a different Endeca base application name; for example, you could set the base application name for the Content istration server to ATGCA, and set the base application name for the Production server to ATGProd. By default, the name of the application is the base application name plus the two-letter language code for the default language for the application; for example, ATGCAen and ATGProden. Be sure to specify the default language (in this case, en) in the /atg/endeca/ApplicationConfiguration component’s defaultLanguageForApplications property for each ATG server instance. defaultLanguageForApplications=en
Provisioning the Endeca Applications For each Endeca application you create, you must provision it by running the initialize_services.sh|bat script found in the application’s /control directory. Therefore, if you have six Endeca applications, you must invoke this script six times. The initialize_services.sh script is found in the following location /endeca/Endecaapplication-directory/your-application/control/.

Oracle ATG – Endeca Integration
Configuring the ATG Server Instances in CIM You must configure your ATG server instances for an ATG-Endeca integration environment using the Configuration and Installation Manager (CIM). ATG Product Selection To configure your server instances to use the ATG-Endeca integration, select ATG-Endeca Integration and Oracle ATG Web Commerce in the Product Selection menu. If your installation includes Oracle ATG Commerce Reference Store, you can select Oracle ATG Commerce Reference Store instead. Your server installations will automatically include ATG Commerce and the ATG-Endeca integration, because Commerce Reference Store requires them. ATG Server Instance Creation During your ATG server instance configuration, you must provide information about your Endeca environment so that the ATG server instance can communicate with Oracle Endeca Commerce. The required settings and their defaults are provided in the table below.
After your ATG server instances are configured in CIM, start them in preparation for indexing.

Oracle ATG – Endeca Integration
Configuring the ApplicationConfiguration Component The atg.endeca.configuration.ApplicationConfiguration class provides a central place for configuring various global settings, including language configuration options and application naming. The ATG-Endeca integration includes a component of this class, /atg/endeca/ApplicationConfiguration. The following are key properties of this component.
a. locales - An array of the locales to generate records for.
b. defaultLanguageForApplications - The two-letter code for the default language for the application. This should be set only if there is a single MDEX for all languages being indexed. By default the value of this property is null.
c. baseApplicationName - The base string used in constructing the Endeca EAC application names. The default setting is ATG. You can override the default when you use CIM to configure your ATG environment. d. keyToApplicationName - A map of application keys to application names. You can use this property to override the default application naming convention discussed in Determining the Number of Endeca Applications to Create. For example, if an environment s English, Spanish, and German, and there is a separate Endeca application for each language, you can specify the application names like this. keyToApplicationName=\ en=MyEnglishApp,\ es=MySpanishApp,\ de=MyGermanApp The application keys in this case are the two-letter language codes. An array of the keys is stored in the read-only applicationKeys property. If there is a single application, the key is default. You can specify the application name like this. keyToApplicationName=\ default=MyApp defaultApplicationKey
Page 8
Oracle ATG – Endeca Integration The key of the application to use if the current application cannot be determined. If there is a separate application for each language, the first key listed in the applicationKeys property is the default, unless you change the default by explicitly setting the defaultApplicationKey property to a different key. If there is only one Endeca application, you do not need to set this property; it will automatically be set to default. e. workbenchHostName - The fully qualified host name, including the domain, of the machine running the Endeca Workbench. You can specify this setting when you use CIM to configure your ATG environment. f. workbenchPort - The port number for accessing the Endeca Workbench. The default setting is 8006. You can override this default when you use CIM to configure your ATG environment.

Starting the Indexing Process The indexing process can be started in two ways i.e. automatically as part of running a full deployment through ATG Content istration or manually using the Dynamo Server . Increasing the Transaction Timeout and Datasource Connection Pool Values Depending on your application server, you may need to increase the transaction timeout and datasource connection pool settings in order for indexing to run successfully. Increasing the Transaction Timeout If indexing is not successful, it may be related to the transaction timeout setting in your application server. Oracle ATG recommends setting a transaction timeout of 300 seconds or greater. All ed application servers time out long-running transactions by marking the active transaction as rolled back which can result in problems when indexing. If your indexing process fails, try increasing the transaction timeout setting. Increasing the Datasource Connection Pool Oracle ATG recommends setting the data source connection pool maximum capacity to 30 or greater for all of your data sources. Indexing As Part of a Deployment You can configure your environment so that when you run a deployment in Content istration, indexing is automatically started after the deployment is finished. a. To make this automatic triggering occur, add the following three components and their configuration to the localconfig layer for your Content istration server. /atg/commerce/endeca/index/CategoryToDimensionOutputConfig b.
Specify the following property for the CategoryToDimensionOutputConfig component:
targetName=Production c. Specify the following property for the /atg/commerce/search/ProductCataputConfig component. targetName=Production d. Specify the following properties for the /atg/search/SynchronizationInvoker component. host=atg-production-server-host rmi=8860
Page 10
Oracle ATG – Endeca Integration Manually Starting the Indexing Process a. To manually start an indexing job, to ATG Dynamo istration for the appropriate ATG server instance. b. Navigate to/atg/commerce/endeca/index/ProductCatalogSimpleIndexing component. c. From here, click Baseline Index to start a baseline index, or Partial Index to start a partial update. Monitoring the Indexing Process Regardless of how an indexing process has been started, you can monitor its progress in ATG Dynamo istration by viewing the/atg/commerce/endeca/index/ProductCatalogSimpleIndexing component. Each phase of the indexing process is listed in the table under Indexing Job Status. To dynamically refresh the window, enable the Auto Refresh option below the table.
Page 11
Oracle ATG – Endeca Integration
Viewing the Indexed Data You can view the indexed data residing in your MDEX engines using Oracle Endeca’s JSP Reference Implementation. a. In a browser, navigate to http://host:port/endeca_jspref, where host:port refers to the name and port of the server hosting the Endeca Tools and Frameworks installation, for example: http://localhost:8006/endeca_jspref b. Click the ENDECA-JSP Reference Implementation link. c. Enter an MDEX host and port, and then click Go.

ATG Modules The main ATG-Endeca integration modules are.
Note that when you assemble an application that includes any of the modules listed in the table above, the DAF.Search.Base and DAF.Search.Index modules are automatically included in the EAR file as well. These modules contain core repository indexing classes that are subclassed in the Endeca-specific modules. In addition, some of the Endeca-specific modules pull in classes from other search modules through the ATG-Class-Path entries in their manifest files.

Oracle ATG – Endeca Integration
Overview of Indexing To make your product catalog available for searching, the Oracle ATG Web Commerce platform must transform the data into the appropriate format, and then submit this data to Oracle Endeca Commerce for indexing. The process of indexing ATG product catalog data in Oracle Endeca Commerce works like this. 1. ATG components transform the catalog repository data into Endeca records that represent Endeca properties, dimensions, and schema. a. Properties of ATG products and SKUs are used to create Endeca properties and nonhierarchical dimensions. b. The ATG category hierarchy is used to create a hierarchical category dimension in Oracle Endeca Commerce. The hierarchy of repository item types in the product catalog is used to create another hierarchical Endeca dimension. c. An Endeca schema is created by examining the set of ATG properties to be indexed. 2. The generated records are submitted to Endeca CAS data, dimension value, and schema record stores. 3. The Endeca EAC is invoked, which creates Forge processes that process the record stores and invoke indexing.
Page 14
Oracle ATG – Endeca Integration
Indexable Classes The ATG platform includes an interface, atg.endeca.index.Indexable, that is implemented by the classes responsible for creating Endeca records. Key classes that implement this interface include.
atg.endeca.index.EndecaIndexingOutputConfig atg.commerce.endeca.index.dimension.CategoryTreeService atg.endeca.index.dimension.RepositoryTypeHierarchyExporter atg.endeca.index.schema.SchemaExporter
EndecaIndexingOutputConfig Class The main class used to specify how to transform repository items into records is atg.endeca.index.EndecaIndexingOutputConfig. The ATG-Endeca integration includes two components of this class.
/atg/commerce/search/ProductCataputConfig /atg/commerce/endeca/index/CategoryToDimensionOutputConfig
Each EndecaIndexingOutputConfig component has a number of properties, as well as an XML definition file, for configuring how repository data should be transformed to create Endeca records. ProductCataputConfig Component The ProductCataputConfig component specifies how to create Endeca data records that represent items in the ATG product catalog. Each record represents either one product or one SKU (depending on whether you use product-based or SKU-based indexing), and contains the values of the ATG properties to be included in the index. In addition, each record includes properties of parent and child items. For example, a record that represents a product includes information about its parent category’s properties, as well as information about the properties of its child SKUs. This makes it possible to search category and SKU properties as well as product properties when searching for products in the catalog. Multi-value properties are given names without array subscripts. For example, a product repository item might have multiple child sku items, each with a different value for the color property. In the output record there will be multiple entries for sku.color. The following is an XML representation of a portion of a Commerce Reference Store record. Note that the actual records submitted to the CAS data record store are in a binary object format, not XML.
Page 15
Oracle ATG – Endeca Integration
CategoryToDimensionOutputConfig Component The CategoryToDimensionOutputConfig component specifies how to create Endeca dimension value records that represent categories from the ATG product catalog. This category dimension makes it possible to use Oracle Endeca Commerce to navigate the categories of a catalog. CategoryToDimensionOutputConfig creates dimension values using a special representation of the category hierarchy that is generated by the/atg/commerce/endeca/index component. The following example shows an XML representation of a portion of a category dimension value record generated by CategoryToDimensionOutputConfig.
Page 16
Oracle ATG – Endeca Integration
CategoryTreeService Class The ATG-Endeca integration uses the category hierarchy in the ATG product catalog to construct a category dimension in Oracle Endeca Commerce. In some cases, the hierarchy cannot be translated directly, because ATG’s catalog hierarchy s categories with multiple parent categories, while Endeca requires each dimension value to have a single parent. For example, suppose you have the following category structure in your product catalog.
Page 17
Oracle ATG – Endeca Integration
To deal with this structure, the ATG-Endeca integration creates two different records for the Men’s Shoes dimension value, one for each path to this category in the catalog hierarchy. These paths are computed by the atg.commerce.endeca.index.dimension.CategoryTreeService class. The ATG-Endeca integration includes a component of this class, /atg/commerce/endeca/index/CategoryTreeService. This component, which is run in the first phase of the indexing process, creates data structures in memory that represent all possible paths to each category in the product catalog. A category can have multiple parents, and those parents and their ancestors can each have multiple parents, so there can be any number of unique paths to an individual category. The CategoryToDimensionOutputConfig component then uses the /atg/commerce/endeca/index/CategoryPathVariantProducer component to create multiple records for each category, one for each path computed by CategoryTreeService. For each path, the corresponding record uses the pathname as the value of its dimval.spec property; this makes it possible to differentiate records that represent different paths to the same category. In the example above, two records are created for the Men’s Shoes category. The dimval.spec entry in one of the records might be.
The dimval.spec entry in the other record for the category might be.
Page 18
Oracle ATG – Endeca Integration RepositoryTypeHierarchyExporter Class The atg.endeca.index.dimension.RepositoryTypeHierarchyExporter class creates Endeca dimension value records from the hierarchy of repository item types in the product catalog, and submits those records to the CAS dimension values record store. This dimension is not typically displayed on a site, but can be used in determining which other dimensions to display. For example, Commerce Reference Store has a furniture-sku subtype that includes a woodFinish property that can be used as an Endeca dimension. A site can include logic to detect whether the items returned from a search are of type furniture-sku, and display the woodFinish dimension if they are. The ATG-Endeca integration includes a component of class RepositoryTypeHierarchyExporter, /atg/commerce/endeca/index/RepositoryTypeDimensionExporter, that is configured to work with the ProductCataputConfig component. The RepositoryTypeDimensionExporter component outputs dimension value records for the entire repository item types referred to in the ProductCataputConfig definition file, as well as the ancestors and descendants of those item types. RepositoryTypeDimensionExporter does not create records for any item types that are not part of the hierarchy mentioned in the definition file. The following example shows a record produced by the RepositoryTypeDimensionExporter component for the product item type.
SchemaExporter Class The atg.endeca.index.schema.SchemaExporter class is responsible for generating schema records and submitting them to the Endeca schema record store. The /atg/commerce/endeca/index/SchemaExporter component of this class examines the ProductCataputConfig definition file and generates a schema record for each ATG property that is output. The schema record indicates whether the ATG property should be treated as a property or a dimension by Oracle Endeca Commerce, whether it should be searchable, and the data type of the property or dimension.
Page 19
Oracle ATG – Endeca Integration
For example, the following is an XML representation of a schema record for the product.description property, which identifies it as a searchable Endeca property whose data type is string.
Page 20
Oracle ATG – Endeca Integration
Submitting the Records Once the records have been generated, they are submitted to the appropriate CAS record stores by components of classatg.endeca.index.RecordStoreDocumentSubmitter. The ATG platform includes three components of this class, each of which is configured to submit to a different record store.
/atg/endeca/index/DataDocumentSubmitter -- Submits records to the data record store (for example, ATGen_en_data). /atg/endeca/index/DimensionDocumentSubmitter -- Submits records to the dimension values record store (for example, ATGen_en_dimvals). /atg/endeca/index/SchemaDocumentSubmitter -- Submits records to the schema record store (for example, ATGen_en_schema).
The EndecaIndexingOutputConfig, RepositoryTypeHierarchyExporter, and SchemaExporter classes each have a documentSubmitter property that is used to specify a document submitter component to use to submit records to the appropriate CAS record store. The following table shows default values of the documentSubmitter property of each component of these classes.
Page 21
Oracle ATG – Endeca Integration
Managing the Process The atg.endeca.index..SimpleIndexing class provides a mechanism for managing the process of generating records, submitting them to Endeca, and invoking indexing. The ATG-Endeca integration includes a component of this class /atg/commerce/endeca/index/ProductCatalogSimpleIndexing. The page for this component in the Component Browser of the ATG Dynamo Server presents a simple interface for controlling and monitoring the process.
After the records are generated and submitted to Oracle Endeca Commerce, ProductCatalogSimpleIndexing calls the /atg/commerce/endeca/index/EndecaScriptService component (of class atg.endeca.eacclient.ScriptIndexable). This component is responsible for invoking Endeca Application Controller (EAC) scripts that trigger indexing. The UI provides buttons for initiating an Endeca baseline index or a partial update. Note that even if you click Partial Index, a baseline update may be invoked if the changes since the last baseline update necessitate it.
Page 22
Oracle ATG – Endeca Integration
Configuring the Indexing Components Here we discuss about the indexing-related Nucleus components in the ATG-Endeca integration, what they do, how they are configured, and how you can modify them to alter various aspects of indexing.
Page 23
Oracle ATG – Endeca Integration
IndexingApplicationConfiguration Component The atg.endeca.index.configuration.IndexingApplicationConfiguration class provides a central place for configuring various indexing settings. The ATG-Endeca integration includes a component of this class, /atg/endeca/index/IndexingApplicationConfiguration. This component is configured by default with typical settings, but you can override these defaults when you use CIM to configure your ATG environment.
a. CASHostName = the hostname of the machine running CAS. The default setting is. CASHostName=localhost b. CASPort= the port number of the machine running CAS. The default setting is. CASPort=8500 c. eacHostName = the hostname of the EAC server. The default setting is. eacHost=localhost d. eaort = the port used by the EAC server. The default setting is. eaort=8888 e. applicationConfiguration = the component of class atg.endeca.configuration.ApplicationConfiguration used to configure global settings for the integration. The default setting is. applicationConfiguration=/atg/endeca/ApplicationConfiguration
Page 24
Oracle ATG – Endeca Integration
EndecaIndexingOutputConfig Components The atg.endeca.index.EndecaIndexingOutputConfig class has a number of properties that configure various aspects of the record creation and submission process. a. definitionFile = The full Nucleus pathname of the XML indexing definition file that specifies the repository item types and properties to include in the Endeca records. For the /atg/commerce/search/ProductCataputConfig component, this property is set as follows. definitionFile=/atg/commerce/endeca/index/product-sku-output-config.xml For /atg/commerce/endeca/index/CategoryToDimensionOutputConfig, this property is set as follows. definitionFile=/atg/commerce/endeca/index/category-dim-output-config.xml b. repository = The full Nucleus pathname of the repository that the definition file applies to. For both the ProductCataputConfig and CategoryToDimensionOutputConfig, this property is set to the product catalog repository. repository=/atg/commerce/catalog/ProductCatalog
Note that in an ATG Content istration environment, the repository should not be set to a versioned repository. Instead, it should be set to the corresponding un-versioned target repository. For example, an EndecaIndexingOutputConfig component for a product cata an ATG Content istration environment could be set to. repository=/atg/commerce/catalog/ProductCatalog_production c. repositoryItemGroup = A component of a class that implements the atg.repository.RepositoryItemGroup interface. This interface defines a logical grouping of repository items. Items that are not included in this logical grouping are excluded from the index. For the CategoryToDimensionOutputConfig component, this property is set by default to null (so no items are excluded). For the ProductCataputConfig component, repositoryItemGroup property is set by default to. repositoryItemGroup=/atg/commerce/search/IndexedItemsGroup The IndexedItemsGroup component uses this targeting rule set to select only products that have an ancestor catalog:
Page 25
Oracle ATG – Endeca Integration
For the CategoryToDimensionOutputConfig component: documentSubmitter=/atg/endeca/index/DimensionDocumentSubmitter e. bulkLoader = A Nucleus component of class atg.endeca.index.RecordStoreBulkLoaderImpl. This is typically set to /atg/search/repository/BulkLoader. Any number of EndecaIndexingOutputConfig components can use the same bulk loader.

Oracle ATG – Endeca Integration
ProductCatalogSimpleIndexing The /atg/commerce/endeca/index/ProductCatalogSimpleIndexing component (of class atg.endeca.index..SimpleIndexing) manages the process of generating records, submitting them to Oracle Endeca Commerce, and invoking indexing. The page for this component in the Component Browser of the ATG Dynamo Server presents a simple interface for controlling and monitoring the process. The SimpleIndexing class defines indexing in of an indexing job, which is made of up indexing phases, which in turn contain indexing tasks. Each indexing task is responsible for executing an individual Indexable component. Tasks within a phase may run in sequence or in parallel, but in either case all tasks in a phase must complete before the next phase can begin. By default, the ProductCatalogSimpleIndexing defines three phases. 1. PreIndexing -- Runs /atg/commerce/endeca/index/CategoryTreeService.
2. RepositoryExport -- Runs these components in parallel: /atg/commerce/endeca/index/SchemaExporter /atg/commerce/endeca/index/CategoryToDimensionOutputConfig /atg/commerce/endeca/index/RepositoryTypeDimensionExporter /atg/commerce/search/ProductCataputConfig 3. EndecaIndexing -- Runs /atg/commerce/endeca/index/EndecaScriptService, which invokes Endeca indexing scripts. You can invoke indexing jobs manually through the ProductCatalogSimpleIndexing interface. In addition, the SimpleIndexing class implements the atg.service.scheduler.Schedulable interface, so it is also possible to configure the ProductCatalogSimpleIndexing component to invoke indexing jobs automatically on a specified schedule. Note: to know about more properties then refer this link

Oracle ATG – Endeca Integration
Specifying Properties for Indexing This section describes how to specify various properties of catalog items for inclusion in the Endeca MDEX, and options for how these properties should be handled. Specifying Multi-Value Properties In most cases, you specify a multi-value property, such as an array or Collection, using the property element, just as you specify a single-value property. In the following example, the features property stores an array of Strings.
Notice that features is specified in the same way as creationDate, brand, and displayName, which are all single-value properties. The output will include a separate entry for each value in the features array. If a property is an array or Collection of repository items, you specify it using the item element, and set the is-multi attribute to true. For example, in a product catalog, a product item will typically have a multi-valued childSKUs property whose values are the various SKUs for the product. You might specify the property like this.
Specifying Map Properties To specify a Map property, you use the item element, set the is-multi attribute to true, and use the mapiteration-type attribute to specify how to output the Map entries. If the Map values are primitives or Strings, set map-iteration-type to wildcard, as in this example.
In the output, the Map keys are treated as subproperties of the Map property, and the Map values are treated as the values of these subproperties. All of the Map entries are included in the output. So, for example, the output from the definition file entry shown above might look like this.
Page 28
Oracle ATG – Endeca Integration
If you want to output only a subset of the Map entries, explicitly specify the keys to include, rather than using the wildcard character (*). For example.
Maps of Repository Items If the Map values are repository items, set map-iteration-type to values, and specify the properties of the repository item that you want to output. For example, suppose you want to index a productInfos Map property whose keys are product IDs and whose values are productInfo items.
The output will include displayName and size tags for each productInfo item in the Map. In this case, the Map keys are ignored, the properties of the repository items are treated as subproperties of the Map property, and the values of the items are treated as the values of the subproperties. The output looks like this.
Page 29
Oracle ATG – Endeca Integration Specifying Properties of Item Subtypes A repository item type can have subtypes that include additional properties that are not part of the base item type. This feature is commonly used in the Oracle ATG Web Commerce catalog for the SKU item type. A SKU subtype might add properties that are specific to certain SKUs but which are not relevant for other SKUs. When you list properties to index, you can use the subtype attribute of the property element to specify properties that are unique to a specific item subtype. For example, suppose you have a furniture-sku subtype that adds properties specific to furniture SKUs. You might specify your SKU properties like this.
This specifies that the description and color properties should be included in the output for all SKUs, but for SKUs whose subtype is furniture-sku, the woodFinish property should also be included. The item element also has a subtype attribute for specifying a subtype-specific property whose value is a repository item. If woodFinish is a repository item, the example above would look something like this.
Specifying a Default Property Value You may find it useful to specify a default value for certain indexed properties. For example, suppose you are indexing address data, and for some addresses no value appears in the repository for the city property. In these cases, you could set the property value in the index to be “city unknown.” A could then search for this phrase and return the addresses whose city property is null. To set a default value, you use the default-value attribute of the property element. For example.
Page 30
Oracle ATG – Endeca Integration Specifying Non-Repository Properties When you index a repository, you can include in the index additional properties that are not part of the repository itself. For example, you might want to include a creationDate property to record the current time when a record is created. The value for this property could be generated by a custom property accessor that invokes the Java Date class. To specify a property like this, use the is-non-repository-property attribute of the property element. This attribute indicates that the property is not actually stored in the repository, and prevents warnings from being thrown when the IndexingOutputConfig component starts up. Note that you must also specify a custom property accessor that is responsible for obtaining the property values.
If no actual property accessor is needed, set the property-accessor attribute to null. For example, you might do this if you have a default value that you always want to use for the property.
Suppressing Properties The output record automatically includes certain standard JavaBean properties of the RepositoryItem object. These properties provide information that identifies the repository items represented in the record, and they are indicated in the definition file by a dollar-sign ($) prefix: $repositoryId, $repository.repositoryName, and $itemDescriptor.itemDescriptorName. (The dollar-signs are removed by default in the output records, because Endeca property names cannot include them.) You may want to return these properties in search results, to enable accessing the indexed repository and repository items in page code. Typically you would do this for the document-level item type. For other item types, you may not need these properties. If you do not need these properties, it is a good idea to exclude them from the index, as they may significantly increase the size of the index. To suppress one of these properties, specify the property in the indexing definition file with the suppress attribute. For example.
Renaming an Output Property By default, the name of a property in an output record is based on its name in the repository, with modifications applied based on the values of the replaceWithTypePrefixes, prefixReplacementMap, and suffixReplacementMap properties of the EndecaIndexingOutputConfig component.
