I am not sure I understand the problem. In RDF any non-literal can be represented as a URI or a local id and can therefore be the subject of an assertion (triplet). How can there not be a place to hang something? You can hang anything anywhere!
Are we talking here about XML Schema validated XML representation of RDF?

In our GBIF/EOL/Plazi SPM project, Terry Catapano and I have formed the conclusion (I hope wrong...) that there is not any place on several lsidvoc objects to hang an lsid (or any other GUID) asserted to identify that object. For example, we don't see any place to put one on a TaxonConcept or on a PublicationCitation. In the October 1 example at http://wiki.tdwg.org/twiki/bin/view/SPM/PlaziEOLProject we have a placeholder hack using
<tc:TaxonConcept rdf:ID="_tc2"> <tc:nameString xml:lang="en">Dodous bispinosus</tc:nameString> tc:hasInformation rdf:resource="urn:lsid:biosci.ohio-state.edu:osuc_concepts:143647"/ ... </tc:TaxonConcept>
but this is not valid in the tdwg ontology because hasInformation requires an InfoItem as its object.
We use other objects that face this problem, e.g. TaxonName, and I guess it is quite a broad issue (or not an issue at all if we are wrong).
Can someone recommend a valid way to address this, either for these three objects, or preferably, in general? If so, thanks in advance. If we are right, how about adding an InfoItem class named GUID, that includes an enumeration of the usual suspects, suitably typed.
