If it helps, here's a spreadsheet where we're attempting to track all of the graph database vendors https://derwen.ai/s/52hztjkknx6n Please ping me if there are others to add?
MarkLogic? TIBCO?
Here's some about RDF work in MarkLogic https://docs.marklogic.com/guide/semantics/intro
Hi. The site db-engines keeps list of DBs, also RDF stores. It may help collecting info. https://db-engines.com/en/ranking/rdf+store
DB-Engines has been really helpful for comparisons. Another site that provides similar kinds of comparisons is https://www.capterra.com/
What about Crux? Seems on the mysterious border lands of graph: https://github.com/juxt/crux Few more to add to the OSS list: TerminusDB link is here: https://github.com/terminusdb/terminusdb Arango: https://github.com/arangodb/arangodb DGraph: https://github.com/dgraph-io/dgraph Fluree: https://github.com/fluree/db Janus: https://github.com/JanusGraph/janusgraph Orient: https://github.com/orientechnologies/orientdb TypeDB: https://github.com/vaticle/typedb I thought Virtuoso was open source, but I can't see a license file in the repo? (https://github.com/openlink/virtuoso-opensource) Finally - cannot believe how many are built on RocksDB -> you can add TypeDB to that list as I just discovered. Facebook obviously giving something good to the world 😁
Virtuoso has a GPL license (although someone on their team committed a symlink to it, which breaks in GH)
