Most of the interfaces in the javax.xml.registry.infomodel package represent data that is held within the registry itself and is of a type that the registry understands. This is not the case for an ExtrinsicObject . The ExtrinsicObject interface represents information that does not have any meaning to and is not interpreted by the registry, which treats it simply as data and stores it in an associated repository from which it can be retrieved on demand. To add an ExtrinsicObject to the registry, use the LifeCycleManager createExtrinsicObject( ) method, which requires a DataHandler that can be used to retrieve the data to be written to the repository as a byte stream. Once a ExtrinsicObject is created, you can use the getRepositoryItem( ) method to get a DataHandler that retrieves its content from the repository and the getMimeType( ) method to get the MIME type of the data. The setOpaque( ) method can be used to mark the data as opaque , so that the registry should not attempt to interpret it in any way. This might be done if the data is encrypted before being submitted to the registry.

Since ExtrinsicObject s require storage outside the registry, they represent a level 1 feature.
