Thad, These mappings can end up in their own special named graph, in a quad store. Net effect, massaging and improvements can occur forever without turning anything on its head. For instance, I can use the mappings named graph as the basis for an inference rule that's only invoked conditionally (in the case of Virtuoso that would via a pragma). I will update or make a new blog post with live examples. Anyway, we should be set :) Kingsley > > > On Mon, Oct 17, 2016 at 1:26 PM Kingsley Idehen > <kide...@openlinksw.com <mailto:kide...@openlinksw.com>> wrote: > > On 10/11/16 2:48 PM, Thad Guidry wrote: >> Kingsley, >> >> You might ask others on the list who could help more with >> providing the WD - Schema.org mappings or get them into a format >> that you want...or an RDF dump file. >> >> I just don't have the knowledge to assist you with that via >> SPARQL.
