Ah, I see, though I think it would be handy if you could add a single dc property instead of reading the whole DC datastream, inserting the new property into it and resubmittting the modified datastream. I understand this is not the primary use case for the addRelationship method, but it could be a secondary one.
Anyway, thanks for clearing this up.

Hi Egbert That is by design - the relationships methods are for manipulating relationships expressed in RELS-EXT and RELS-INT. The other triples generated (which include object-datastream relationships, object and datastream properties, and of course DC) cannot be manipulated with the relationships methods.
