[tdwg-content] dwc:associatedOccurrences

[Bob Morris]

I'm on John's side on this, but it is not necessarily an easy path
forward if you want the CVs to work with multiple technologies and
tools. That remains a research problem that is addressed in more than
one pending proposal to the U.S. NSF's SI2 program
http://www.nsf.gov/pubs/2010/nsf10551/nsf10551.htm

 As an example, while http://rs.tdwg.org/dwc/rdf/dwcterms.rdf will
load on its own into Protege 4.1beta,  and attempt to import it into
an otherwise valid OWL ontology throws a NullPointerException. (This
is probably a simple programming error, but in general, Protege4 has
design propensities favoring actual OWL ontologies. The result is that
even where dwc.rdf loads, the perfectly reasonable minimalist style of
dwc.rdf causes all terms to appear as individuals instead of
properties. That shouldn't impede their use in an OWL ontology, but
the UI of Protege makes it unpleasant, if not impossible).
