Interface URIGenerator

All Known Implementing Classes:

DOIHandleURIGenerator, DOIURIGenerator, HandleURIGenerator, LocalURIGenerator

public interface URIGenerator

Please use RDFUtil.generateIdentifier(Context, DSpaceObject) and org.dspace.rdf.RDFUtil#generateGraphURI(Context, DSpaceObject) to get URIs for 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. RDFizer.RDFizer() uses a URIGenerator to generate URIs to Identify DSpaceObjects in RDF. You can configure which URIGenerator should be used. See DSpace documentation on how to configure RDFizer.

Method Summary

Modifier and Type	Method and Description
String	generateIdentifier(Context context, DSpaceObject dso) Shortcut for generateIdentifier(context, dso.getType(), dso.getID(), dso.getHandle()).
String	generateIdentifier(Context context, int type, UUID id, String handle, List<String> identifiers) Generate a URI that can be used to identify the specified DSpaceObject in RDF data.

Method Detail

generateIdentifier

String generateIdentifier(Context context,
                          int type,
                          UUID id,
                          String handle,
                          List<String> identifiers)
                   throws SQLException

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.

Parameters:

context -

type -

id -

handle -

identifiers -

Returns:

May return null, if no URI could be generated.

Throws:

SQLException
