Show HN: TerminusDB – An open source in-memory graph database

I checked the origin of the project and it seems to be an European grant to a few universities working on Semantic Web. Given the track record of this technology I’ll pass my turn. Neither the home page nor the doc provide any compelling arguments or killer feature for it’s use over existing solutions.

I’m not convinced either that a strong schema is really important for a graph database. In fact, even in OOP long chain of inheritance have proven bad practice. I also found myself that working with flat-type (no inheritance) nodes and edges simplify the code a lot.

Is this database used on any deployed project?

You checked the origin as in you read my comment on this thread? Pretty clear when I said it started in Trinity College Dublin working with linked data. Semantic web certainly suffers from true believers that refuse any break with orthodoxy, but there is a core of wisdom & imho if you can do something practical the best ideas can emerge.

Without schemata, you end up with spaghetti pretty quickly and no way to ensure data-quality. It's also impossible to treat segments of the graph as documents. With a strong schema you can move seemlessly between objects and graph view.

It is currently deployed in several industrial settings.
