Hey! I started on the data modeling language Link, which doesn't do much by itself. I am going to use BaseLink for the compiler, at first just compiling to JavaScript.

I agree that it feels like multiple projects are converging on something that is ripe (or close).
I have done some deep-digging for markup languages and came across more than one project in this space. (I've added Jevko to my list; https://twitter.com/abathur/status/1582492437984837632)
You may have already seen it as well, but you might also find https://github.com/teamtreesurf/link interesting.

These datatype implementations are currently stored in the wolf repo (the "stdlib"). In addition, a high-level Rails-like framework is planned to be in the crow repo. This separation is here so on the one-hand the "stdlib" is minimal, while the framework is robust and all-inclusive. For an example of some code, check out for instance this first pass at a dynamic array, here is a small snippet.
