For anyone who is interested in developing their own relations, here's a link to our in-house RDF schema, which we store as an XML datastream in our repository:
http://digital.library.wisc.edu/1711.dl/rdf/1.0/relations Our namespace is http://digital.library.wisc.edu/1711.dl/rdf/1.0/relations And here's a sample rdf triple we include in an RELS-EXT datastreams: <info:fedora/1711.dl:26AACRSQN53TV85> <http://digital.library.wisc.edu/1711.dl/rdf/1.0/relations#isMemberOfProject> <hdl:1711.dl/AerialWisconsin> The schema is purely for documentation right now; we're not using it in any validation or workflow steps yet, and Fedora neither knows nor cares if it exists. We could just as easily make up relations not in any schema and put them in our RELS_EXT datastreams with no side effects (they would still be indexed and queryable in the resource index). At some point, we'll probably want to turn this into a real ontology, and then use some RDF validation tools to validate our relations. Note that the namespace and the URL for the schema are NOT the same thing, though they may overlap (as in our case). A namespace simply should be unique, and follow namespace URI standards. -- Scott Steve Bayliss wrote: > Hi Ilse > > You don't have to create custom rdfs for custom relationships that you want > to use between your Fedora objects.
