ISO GQL just landed in Virtuoso Open Source.
Most GQL stops at labeled property graphs. This one runs over RDF — hyperlinks as IDs, ontology use, platform-agnostic knowledge graphs. Same idea as SPASQL for SQL.

What you can do: pattern matching, path modes (WALK/TRAIL/SIMPLE/ACYCLIC), INSERT/DELETE/SET, virtual + physical property graphs, plus Virtuoso extensions — inference, owl:sameAs, geospatial, RDF 1.2.
Why GQL on Virtuoso: property-graph syntax over RDF, translated to SPARQL — so you keep the SPARQL engine (optimizer, paths, geospatial) while writing MATCH.

does GQL over RDF follow owl:sameAs when it matches a pattern, or are hyperlinks as IDs just treated as opaque keys? the sameAs joins across graphs are where my entity counts stop being reproducible, and labeled property graphs never had to deal with that
