Make credential-context resolvable

[arnoweiss]

Description

As Operator or Enablement Service Provider for a CX-0018 compliant service,
I want to read the expanded JSON-LD of VCs,
so that I can reliably process and understand their content.

Acceptance Criteria

• https://w3id.org/catenax/credentials/v1.0.0 is resolvable to a JSON-LD context.
• The versioning between the context and the namespace is aligned.

Additional Information

Currently, the samples' @context in the credentials-folder rely on the https://w3id.org/catenax/credentials/v1.0.0 context. It currently resolves to the default path specified in the redirects. The credential-context included in this repository is already in v1.1 so I'm unsure whether it's an appropriate target. Its content would be affected if issue #25 is accepted with further implications for versioning.

I'd be willing to contribute if there's an aligned concept.

@jimmarino - is this on your roadmap? If no, I could pick this up. EDC doesn't need it but I think there's value in it.

Note: The original issue mentions https://w3id.org/catenax/... while there's consensus now that the contexts should reside in the https://w3id.org/tractusx/... namespace.

@arnoweiss If you could pick this up it would be much appreciated.

Created a PR in the https://w3id.org/catenax/ namespace for the credentials [1] and one to register https://w3id.org/tractusx and populate it with a redirect to the policy-jsonld-context [2].

Hey @arnoweiss thanks!

Just a small comment for the links. I would use the published on in GH pages,
since they will be updated automatically in when changed and also GH pages preserve the content type, some libraries complain about the raw.* of GH since the content type i think it's plain/text

You can find the published one here:

Policy Context
https://eclipse-tractusx.github.io/tractusx-profiles/cx/context/policy.context.json

Credentials Context
https://eclipse-tractusx.github.io/tractusx-profiles/cx/context/credentials.context.json

Thanks, I wasn't aware that exists.

As the documents you linked mirror main, it may become an issue that they are mutable. Fetching the context from remote may yield varying results. I think it's good enough for now but this may become an issue further down the road. I'll adjust the linked PRs.

The respective PRs are merged and resolve correctly AFAICT. Please check and close if confirmed.

Thanks @arnoweiss

LGTM!
