Note: This step is required only if you import file assets with the Repository Loader.

As described later in Import Initial File Assets, you use the ATG platform’s Repository Loader to import file assets into the ATG Content Administration system. The Repository Loader uses a set of TypeMapping components to convert files of different types into content repository items, and it uses a TypeMapper component to determine which TypeMapping component to use for a given file.

ATG Content Administration provides a set of TypeMapping components for the default content item descriptors in the PublishingFileRepository, as well as a PublishingTypeMapper component that defines this array of TypeMapping components. These components are located in:

<ATG10dir>/Publishing/base/config/atg/epub/file/typemappers

However, if you intend to import file assets of the custom item types with the Repository Loader, you need to configure additional TypeMapping components to support the custom content item descriptors:

For more information on these tasks, see the Repository Loader chapter in the ATG Repository Guide.

In the FTPFileSystem example, the TypeMapping component for the ftpTextFileAsset item descriptor is named FTPTextFileAssetTypeMapping.properties and looks like this:

$class=atg.repository.loader.TypeMappingImpl

itemDescriptorName=ftpTextFileAsset
repository=/atg/epub/file/PublishingFileRepository
contentHandler=/atg/dynamo/service/loader/typemapping/Xml2RepositoryConten
tHandler
contentIsXML=false
parseContent=false
updatePropertyConfiguration=CONTENT_ITEM_DESCRIPTOR_ID_AND_PATH_PROP
applicationLogging=/atg/epub/file/VersionedLoaderEventListener
contentRootPathProvider=/atg/epub/file/VersionedLoaderEventListener

Similarly, the TypeMapping component for the ftpBinaryFileAsset item descriptor can be named FTPTBinaryFileAssetTypeMapping.properties:

$class=atg.repository.loader.TypeMappingImpl

itemDescriptorName=ftpBinaryFileAsset
repository=/atg/epub/file/PublishingFileRepository
contentHandler=/atg/dynamo/service/loader/typemapping/Xml2RepositoryConten
tHandler
contentIsXML=false
parseContent=false
updatePropertyConfiguration=CONTENT_ITEM_DESCRIPTOR_ID_AND_PATH_PROP
applicationLogging=/atg/epub/file/VersionedLoaderEventListener
contentRootPathProvider=/atg/epub/file/VersionedLoaderEventListener

Finally, the new configuration file to layer on for the PublishingTypeMapper looks like this:

$class=atg.epub.loader.PublishingTypeMapper

typeMappings+=\
  FTPTextFileAssetTypeMapping,\
  FTPBinaryFileAssetTypeMapping

For a description of properties you can configure for TypeMapping and TypeMapper components, see the Repository Loader chapter in the ATG Repository Guide. For more information on the /atg/epub/file/VersionedLoaderEventListener component (referenced in the configuration file examples above), see the ATG Repository Guide.
