Missing context extension in downloaded RO-Crate

[simleo]

Describe the bug

When a workflow that was uploaded as an RO-Crate is subsequently downloaded as an RO-Crate, the metadata file is missing any context extensions from the original one.

To Reproduce

Upload this crate to WorkflowHub (tested on https://dev.workflowhub.eu), then download it as an RO-Crate.

Details

The above example is a Workflow Testing RO-Crate, which uses context extensions defined in the ro-terms test namespace.

The crate's original context was:

    "@context": [
        "https://w3id.org/ro/crate/1.1/context",
        {
            "GithubService": "https://w3id.org/ro/terms/test#GithubService",
            "JenkinsService": "https://w3id.org/ro/terms/test#JenkinsService",
            "PlanemoEngine": "https://w3id.org/ro/terms/test#PlanemoEngine",
            "TestDefinition": "https://w3id.org/ro/terms/test#TestDefinition",
            "TestInstance": "https://w3id.org/ro/terms/test#TestInstance",
            "TestService": "https://w3id.org/ro/terms/test#TestService",
            "TestSuite": "https://w3id.org/ro/terms/test#TestSuite",
            "TravisService": "https://w3id.org/ro/terms/test#TravisService",
            "definition": "https://w3id.org/ro/terms/test#definition",
            "engineVersion": "https://w3id.org/ro/terms/test#engineVersion",
            "instance": "https://w3id.org/ro/terms/test#instance",
            "resource": "https://w3id.org/ro/terms/test#resource",
            "runsOn": "https://w3id.org/ro/terms/test#runsOn"
        }
    ]

While the context in the downloaded crate is:

    "@context": "https://w3id.org/ro/crate/1.1/context"

This is a current limitation of the library, so I've raised an issue in that repository.

Does the python library handle this case?

Thanks!

There is some initial support, but it's not finished yet. I just opened ResearchObject/ro-crate-py#61 to keep track of what's missing.
