Support JSON-LD Framing

[rob-metalinkage]

JSON-LD serialisation can be done in many ways. The JSON-LD framing spec provides a basis for some control.

https://www.w3.org/TR/json-ld11-framing/

JSON-schema specifications could interact with specific JSON-LD frames, but probably not with arbitrary graph structures containing the same information.

Frames to create schemas and compatible serialisations can be generated from class models, and used to create instance documents that could conform to generic JSON APIs. A first cut attempt at building json-schemas from OWL models is at https://github.com/RDFLib/profilewiz/blob/master/profilewiz/Frame.py. Ideally something like this could be used to generate frames to feed into serialisation strategies.

• These are the tests for JSON-LD 1.1 Framing:
  • https://w3c.github.io/json-ld-framing/tests/
  • PyLD runs them:
    • https://github.com/digitalbazaar/pyld/blob/316fbc2c9e25b3cf718b4ee189012a64b91f17e7/tests/runtests.py#L737-L755
  • jsonld.js runs them:
    • https://github.com/digitalbazaar/jsonld.js#frame
    • https://github.com/digitalbazaar/jsonld.js/tree/master/tests
      • https://w3c.github.io/json-ld-framing/tests/
  • rdflib does not yet run any of these tests?
    • rdflib-jsonld: build a test runner
    • rdfib-jsonld: run the json-ld test suite including the framing tests
