JSON-LD cannot validate, only JSON Schema can

[VladimirAlexiev]

JSON-LD is completely orthogonal to JSON Schema:

• JSON-LD cannot validate, JSON Schema can
• JSON-LD explicates JSON terms to URLs, and can add conveniences like datatype info, name graph, container (set/list), etc. JSON Schema doesn't

In addition, while the use of credentialSchema (in particular JSON Schema) is optional in VC, JSON-LD is necessary.

So I'm puzzled by these statements:

• https://w3c-ccg.github.io/vc-json-schemas/v2/index.html#drawbacks

A new version could be introduced that supports [JSON-LD] and removes support for [JSON_SCHEMA].

• https://w3c-ccg.github.io/vc-json-schemas/v2/index.html#alternatives

[JSON-LD] is the most prominent alternative, though it does not provide the same functionality in regards to strict data validation

In particular, the latter should be changed to refer to the RDF Shape languages (SHACL and SHEX), which provide data validation features comparable to JSON Schema

Closely related to #16

My intention, which I can see is less-than-clear, was to state that an LD schema could be embedded into a JSON schema so there's a 1 - 1 mapping between the two.

Yeah I wasn't really aware of these. They could be OK to add but seem quite complex and (potentially) unnecessary compared to JSON Schema which is quite widely adopted.

What is LD Schema?

If you don't like RDF Shapes then delete section Alternatives

[decentralgabe]

What is LD Schema?

Any schema that uses JSON LD, like those here https://schema.org/docs/schemas.html

If you don't like RDF Shapes then delete section Alternatives

My personal preferences have little to do with the specification. It would be dishonest to not share alternatives. If you believe there's an error, please make a contribution.

Closing and will be handled in #122
