How different is it from the semantic Web (schema, RDF, OWL…)? Instead of reinventing something, why not using a well established technology that can also be beneficial for other usages?
Using URIs as identifiers and RDF as interchange format, makes it possible for LLM's and computers to understand well what something really means. It makes it well suited for making sure LLM's and computers understand scientific data and are able to aggregate it.
