Hi Scott, One way to do that would be to get the language code label list from WDQS with this: http://tinyurl.com/y9p7q9l2 SELECT ?label WHERE {?s wdt:P424 ?code; rdfs:label ?label filter (lang(?label) = "en").}
and then stream the list to LDF client [1] requests https://tinyurl.com/ycc3dyce ldf-client https://query.wikidata.org/bigdata/ldf http://fragments.dbpedia.org/2015-10/en "SELECT * WHERE {?s rdfs:label "+ language + "@en . ?s owl:sameAs ?link }" The results would be in JSON from the client. It should give a relatively complete list of WIkidata language code entity corresponding resources in DBpedia Also, an simple way to get a dbpedia resource with TPF is with the entity label which is one of the properties that is the same for both datasets. So, SELECT * WHERE { ?s rdfs:label "German"@en . } will return the matching dbpedia and wikidata resources for that label. This could also perhaps be done with a federated query in WDQS.(untested).
