Hi all,
I'm reading about the Jena support to RDF* and SPARQL*
(https://jena.apache.org/documentation/rdfstar/).
I guess this requires a TDB endpoint, or is there any kind of SPARQL*
support for HTTP endpoints?
HTTP endpoint = Fuseki?
There is RDF-star and SPARQL-star support.
(note renaming - the community has decide that RDF*/SPARQL* refers to
Olaf's original work ... and is search engine unfriendly. The community
work is called RDF-star/SPARQL-star.)
The current SPARQL-star details need to change; the direction is now
clear (specifically SA mode, not PG mode) but for many cases, it's details.
I'm thinking of both the case where the remote endpoint has star
support, and the idea of translating SPARQL* constructs into patterns
based on the rdf: vocabulary (rdf:Statement, rdf:subject, etc).
No need - send a SPARQL-star query.
(I have code that does RDF-star<->reification. There's an open JIRA
somewhere.)

If that isn't available (as it seems), would it make sense? For
star-supporting triple stores, is there any specification about the
corresponding HTTP(*) API for the SPARQL endpoint? For plain SPARQL
endpoints, would the idea above be feasible (with ARQ extensions)?
Thanks in advance,
Marco.
