Hi Kingsley,The main reason we use new URIs is because we want to assert new triples (based on the DBpedia ontology) and make this knowledge dereferencable in the future.
There's no need for minting new URIs for the following reasons:1. An owl:sameAs relation is simply about asserting coreference between two URIs -- so when you merge (smush) to end up with a richer description that applies to either URI
2. An owl:sameAs relation is symmetrical -- i.e., the subject or object role in the relationship (facilitated by the owl:sameAs relation) doesn't change anything.
Maybe we are doing something wrong (and this is why we do an early release) but imo, it's the same reason we didn't use the Wikipedia URIs in DBpedia in the first place.
There's a difference here, Wikidata is publishing RDF model based Linked Data. Wikipedia doesn't publish RDF model based Linked Data.
Re., Wikipedia, also note, that we forward-chained relations in the version we host such that each Wikipedia document URI/URL is the subject of a foaf:primaryTopic relation that has a DBpedia Entity URI as its object -- which enables easy discovery of DBpedia URIs associated with Wikipedia Document URI/URLs using follow-your-nose patterns via a browser or SPARQL query etc..
I was also thinking of a little shorter name like data.dbpedia.org <http://data.dbpedia.org>, or db ;)
Best you stick with the Wikidata Linked Data URIs. All other options are problematic cost-generating vectors.
Although using just dbpedia.org <http://dbpedia.org> and moving existing English DBpedia to en.dbpedia.org <http://en.dbpedia.org> would be the best approach (that ain't gonna happen soon)
Correct :-) Kingsley
