Protocols JDBC/ODBC, HTTP/REST, SPARQL Protocol

PGX JDBC driver and SQL/PGQ-over-JDBC cover JDBC/ODBC; the PGX Graph Server REST API and ORDS network/model-management endpoints are a genuine non-SPARQL REST API; the ORDS RDF Graph sparql/1.1 endpoints explicitly implement SPARQL 1.1 Protocol (linked to the W3C spec), so pass_A's inclusion of SPARQL Protocol is correct and pass_B's omission of it is wrong.

License Proprietary

Confirms the current value. Graph features ship inside Oracle Database under Oracle's commercial database license (no extra-cost option since Dec 2019, but still requires a licensed Oracle Database edition).

  • Property Graph and RDF Graph Technologies (RDF/OWL) no longer requires an extra cost license. See Oracle Database Insider blog post for more information.

Released 2005

Confirms the current value. Oracle's own team traces "Oracle Graph" to the RDF Knowledge Graph feature first shipped in Oracle Database 10g Release 2.

Language Java

Confirms the current value with a caveat: Oracle Graph is split. The RDF/property-graph storage lives inside the C-based Oracle Database kernel, but the headline graph analytics engine (PGX, Parallel Graph AnalytiX) that Oracle Graph leads with is written in Java, with a C++ distributed runtime variant.

  • PGX was an official Database add-on, and because the database is officially released for Windows they had to release PGX for Windows as well. PGX is written in Java
