Hi, > apart from Basic Graph Patterns and FILTER, as it is shown in > https://github.com/dkuppitz/sparql-gremlin > <https://github.com/dkuppitz/sparql-gremlin> This was primarily a proof-of-concept. I believe Kuppitz would be more than happy to have someone extend the work and make it “full-fledged.”
