As far as graph-based languages and languages with arbitrary metadata and relationships between objects are concerned, I've been mulling over a language where expressions are represented as RDF graphs and that has built-in support for manipulating RDF graphs. I've use the concepts as an intermediate representation for [mostly numeric] functional expressions in a few different systems (including Factorio's map generator), but haven't yet had the motivation to really flesh it out into a full-blown language. https://github.com/TOGoS/TOGVM-Spec https://github.com/TOGoS/TOGVM-Spec
