This chapter provides an overview of AssetType API and describes the use cases using this API.
This chapter contains the following sections:
Types (Asset Types and Compliance Templates) define the structure of assets. Types consist of two main parts:
Editor
Defines the metadata that is stored for the assets and determines how metadata elements are organized in the Asset Editor.
Viewer
Defines how the metadata elements will be displayed in the asset detail in Oracle Enterprise Repository.
When creating or editing a Type, acceptable value lists and categorization types are used as metadata elements. These metadata elements are referenced by ID in the Editor and Viewer XML for the Type.When creating or editing assets, Types define the metadata elements that are used in the custom data for the asset (Asset.GetCustomData()).
Note:
While the code examples in this section refer to Asset Types, please be aware that the processes described in the use cases can be used to create both Asset Types and Compliance Templates. For more information about Compliance Templates, see Oracle Fusion Middleware Configuration Guide for Oracle Enterprise Repository.
Editor and viewer metadata is represented as CDATA escaped XML. Consequently, if a large number of AssetTypes are returned via a call to assetTypeQuery, it is possible that some XML parsers may exceed their entity expansion limit. On some popular parsers, the default entity expansion limit is set to 64,000. If this limit is exceeded, it can be increased on JAXP compliant processors by passing a command-line parameter called entityExpanionLimit. For example, passing the following parameter to the JVM will increase the entity expansion limit to 5 MB:
java -DentityExpansionLimit=5242880 com.example.MyApp
This section describes the use cases using the Asset Type API. It contains the following topics:
