Add SPARQL-star built-in functions
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.
