I wish there was a defacto/canonical site that housed free papers that people could go search before embarking on these types of efforts. Perhaps there is but when I attempt these types of searches I get directed to pay walled ACM type links or Github "Papers We Love" type links.

You might enjoy https://pldb.io/, which is a paywall free, open source, public domain, database you can browse completely locally, with information on all of these kinds of prior languages.

Funny, someone linked me here. I just posted a project that got a bit of traction related to this: papertalk.xyz

It would certainly be fair to add RDF/triples/semantic web, to prior work. I spent many years exploring that stuff.

We are aiming at roughly the same problem. Our implementation has solved some important details.

Might be worth highlighting some of the problems solved (particularly those that earlier ideas haven't).
