Description copied from interface: URIGenerator

Generate a URI that can be used to identify the specified DSpaceObject in RDF data. Please note that URIs can be generated for DSpaceObjects of the type SITE, COMMUNITY, COLLECTION or ITEM only. Currently dspace-rdf doesn't support Bundles or Bitstreams as independent entity. This method should work even if the DSpaceObject does not exist anymore.

Specified by:

generateIdentifier in interface URIGenerator

Parameters:

context - DSpace Context.

type - Type of the DSpaceObject you want to generate a URI for (e.g. Constants.ITEM.

id - UUID of the DSpaceObject you want to generate a URI for.

handle - Handle of the DSpaceObject you want to generate a URI for.

identifiers - list of identifiers

Returns:

May return null, if no URI could be generated.

Throws:

SQLException - An exception that provides information on a database access error or other errors.
