Re: YASGUI: Web-based SPARQL client with bells ‘n wistles

Hi Bernard,
And if you are going to change things…
I went looking for equivalences (:-)), and found a lot (but not all) of owl:sameAs dbpedia objects that seem to have crept in as strings, e.g. 
<http://rdf.muninn-project.org/ontologies/military#Battalion> owl:sameAs "dbpedia:Battalion"

http://lov.okfn.org/endpoint/lov_aggregator?query=PREFIX+owl%3A+++%3Chttp%3A%2F%2Fwww.w3.org%2F2002%2F07%2Fowl%23%3E%0D%0ASELECT+DISTINCT+*+WHERE+%7B+%3Fs+owl%3AsameAs+%3Fo+%7D%0D%0ALIMIT+100&format=HTML

Best
Hugh
