Idea of #propertygraph on top of #rdf is interesting. It is marry 2 big camps and give more tools and power . #terminusdb go even forward and add more user friendly document based interface for #linkeddata on top of #jsonld that could be translated to #rdf. Unfortunately we still has no tools for #edge and on user device . I see that terminus #hdt store and effective #datalog engine improvemented in #rust give a hope
