RDF

The Resource Description Framework: facts expressed as subject, predicate, object statements (triples) with resolvable identifiers. JSON-LD is one serialisation of it, so every schema.org block on a page is already a small RDF graph, and it can be checked as one - whether its identifiers resolve, whether references point at nodes that exist, whether it parses at all.
