Ontofelia is a self-hosted agent gateway with long-term memory built on OWL ontologies instead of a property graph, an early experiment worth watching.

An early experiment of something I mentioned a few times: it seems all agentic memory systems are based on property graphs. Well, not anymore.

It’s a self-hosted agent gateway that gives your AI a persistent identity, structured long-term memory powered by OWL ontologies, and secure multi-channel communication.

Have not tested it out, only reporting this. I wait until the dust has settled a bit. If you try it out, let us/me know.
