Re: [Bigdata-developers] SPARQL queries in Blazegraph Blueprints

[Bryan T. <br...@sy...>]

Jack,

Per an email thread with MikeP:

addVertex(id) creates the triples:

<id> rdf:type <Vertex> .

addEdge(eid, from, to, type) creates the triples:

<eid> rdf:type <Edge> .
<eid> rdf:type <type> .
<from> <eid> <to> .
<from> <type> <to> .

Thanks,
Bryan
