How come there is no SQLite of Datalog? You can find plenty of implementations of embedded datalog database in a specific language, where the query API is tied to the language. I want to write text datalog queries and access my database from multiple languages. Why doesn’t this exist?
Mozilla was working on the opposite, a Datalog of SQLite, with Mentat, now abandoned: https://github.com/mozilla/mentat
Strikes me as a basically sound idea and it would be lovely if someone picked up the ball.
