Thad, Not getting the point you are trying to articulate i.e., the solution isn't comprised strictly of <https://www.wikidata.org/wiki/Property:P1709> <https://www.wikidata.org/wiki/Property:P1709> relations. I am assuming <https://www.wikidata.org/wiki/Property:P1709> <https://www.wikidata.org/wiki/Property:P1709> identifies equivalentClass relations i.e., <https://www.wikidata.org/wiki/Property:P1709> <https://www.wikidata.org/wiki/Property:P1709> owl:equivalentProperty owl:equivalentClass . You should be able to articulate the equivalent of the following, using SPARQL against Wikidata: SELECT DISTINCT ?s ?relation ?o WHERE { ?s owl:equivalentClass ?o. BIND (owl:equivalentClass AS ?relation) FILTER (isIRI(?s)) FILTER (isIRI(?o)) } LIMIT 100 Live Solution Link: http://lod.openlinksw.com/sparql?default-graph-uri=&query=SELECT+DISTINCT+%3Fs+%3Frelation+%3Fo%0D%0AWHERE+%7B+%3Fs+owl%3AequivalentClass+%3Fo.%0D%0A++++++++BIND+%28owl%3AequivalentClass+AS+%3Frelation%29%0D%0A++++++++FILTER+%28isIRI%28%3Fs%29%29+%0D%0A++++++++FILTER+%28isIRI%28%3Fo%29%29%0D%0A++++++%7D%0D%0ALIMIT+100&format=text%2Fx-html%2Btr&CXML_redir_for_subjs=121&CXML_redir_for_hrefs=&timeout=30000&debug=on Kingsley > > On Mon, Oct 10, 2016 at 1:50 PM Kingsley Idehen > <kide...@openlinksw.com <mailto:kide...@openlinksw.com>> wrote: > > On 10/9/16 1:34 PM, Thad Guidry wrote: >> Kingsley, >> >> The mappings are already in Wikidata (we still have a few >> properties left to map, but the classes are done, except for a >> few in pending.schema.org <http://pending.schema.org>.
