It seems that in what you have "demo:category_mindmapping" is a string (an RDF Literal), not an RDF Resource. The < and > in your query mean that you ask for a resource (and the URI suggests it is a Fedora Object). If there is a Fedora object with PID "demo:category_mindmapping", you can point to that in the RELS-EXT datastream like this: <rdf:Description rdf:about="info:fedora/demo:_3e7189f7a42f4ed7be2969642e469480"> <isInCategory xmlns="http://test/ontologies/ltk/relationships#" rdf:resource="info:fedora/demo:category_mindmapping"></isInCategory> </rdf:Description> I think the query should work then. > > thanks, > > Alistair > Regards, Ben > -------------- > mov eax,1 > mov ebx,0 > int 80 > > On 8 Oct 2011, at 11:40, Alistair Young wrote: > >> can't seem to nail this down.
