Re: [Bigdata-developers] Org Ontology Inferencing

[Kaushik C. <kay...@gm...>]

Pardon my naïveté but how do one load an ontology in a kb while Blazegraph
is being deployed as NanoSparqlServer ?

The actual Org Ontology is at this URL  - http://www.w3.org/ns/org.n3 and
it has the required inverseOf relationship that you mentioned.

What's the best way to tell Blazegraph to go and fetch the same from this
URL and use it for inferencing as I'm adding my document in Update panel.

Much thanks in advance.
