Hi Joel, I changed these so they are now in this form. It is still wrong in the rdf_dump but that will replaced in the next day or two. <owl:Class rdf:about="http://lod.taxonconcept.org/ses/dwAmr#Species"> <foaf:page rdf:resource="http://en.wikipedia.org/wiki/Vanessa_cardui"/> <foaf:page rdf:resource="http://species.wikimedia.org/wiki/Vanessa_cardui "/> <foaf:page rdf:resource="http://www.eol.org/pages/2682820"/> <foaf:page rdf:resource="http://eunis.eea.europa.eu/species/90992"/> Thanks Again, :-) - Pete On Fri, Jun 4, 2010 at 9:00 PM, joel sachs <jsachs@csee.umbc.edu> wrote: > Pete, > > I notice that you use skos:closeMatch (instead of owl:sameAs) to assert > near equivalence amongst species concepts.
