Does Blazegraph support the Graph Store Protocol #236

Closed mikebrules closed 1 year ago

mikebrules commented 1 year ago

Hello - I'm trying to configure Jena to connect to Blazegraph using the Graph Store protocol

https://www.w3.org/TR/sparql11-http-rdf-update/

..but I can't seem to be able to find out what the Graph Store Endpoint would be for a Blazegraph namespace. Does Blazegraph support this function please?

String url = "http://192.168.0.7:9999/blazegraph/namespace/products/sparql"; RDFConnection conn = RDFConnectionRemote.newBuilder() .destination(url) .gspEndpoint("/gsp")

...doesn't seem to work - I can't find any reference to what the path needs to be.

Thanks in advance,

The REST APIs supported by blazegraph are documented here: https://github.com/blazegraph/database/wiki/REST_API

Blazegraph does not support the graph store protocol. There was a conflict with one of the pre-existing REST VERBS for blazegraph. Delete if I recall already had been assigned different semantics for Blazegraph.

Thanks, Bryan
