Hi there!
Through our activities at NeuroLex (
neurolex.org) we are looking at exporting our vocabularies dynamically (check out the RDF feed links on each of the pages there). Additionally, we distribute the NIF Standard ontology from our webpage, which is encoded in OWL, a derivative of RDF. We don't yet conform to all of the Linked Data standards at the moment, but we are looking into it.
What kind of thing would you like to see? What would be most useful to you?
Regards,
--Stephen
