Add SPARQL-star built-in functions #2920

Open abrokenjester opened 3 years ago

abrokenjester commented 3 years ago

See RDF-star editor's draft for upcoming addition to spec: https://w3c.github.io/rdf-star/cg-spec/editors_draft.html#builtin-functions

These are built-in "standardized" variants of several functions RDF4J already supports for working with RDF-star triples: rdf:isTriple, rdf: Statement, rdf:subject, rdf:predicate, and rdf:object.

This will require a re-compilation of the JavaCC grammar, something we should approach with care, and not as a last-minute task, so rescheduling this for 4.0.
