Fix incorrect context reference in error-0042

[rubensworks]

As far as I understand the goal of this test, I think this test may be incorrectly defined. Currently, jsonld.js seems to accept this input, and this fails the test. I assume this is because the list context entry is not used in the JSON-LD document.

This is now https://w3c.github.io/json-ld-api/tests/compact-manifest.jsonld#te001 and is labeled as a 1.0-only test, as compaction to lists of lists is supported in 1.1, which may be why you're seeing jsonld.js pass this test.

The input is in expanded form, thus http://example/list is correct; simply list would fail, as it is not an IRI. The associated context will compact http://example/list to just list, and fail in 1.0, but succeed in 1.1. You can see the manifest entry in the WG test suite is marked as specVersion: json-ld-1.0:

{
  "@id": "#te001",
  "@type": [ "jld:NegativeEvaluationTest", "jld:CompactTest" ],
  "name": "Compaction to list of lists",
  "purpose": "Verifies that an exception is raised in Compaction when attempting to compact a list of lists",
  "option": {"specVersion": "json-ld-1.0"},
  "input": "compact/e001-in.jsonld",
  "context": "compact/e001-context.jsonld",
  "expect": "compaction to list of lists"
}

There should be another test for 1.1, which is expected to succeed.

If I'm correct, test error-0042 currently defines a set of lists, which is allowed in JSON-LD 1.0 as far as I can see (as opposed to a list of lists):

{
  "http://example/list": [{"@list": ["foo"]}, {"@list": ["bar"]}]
}

That is because even though the context defines "@container": "@list", it has no relation to the JSON-LD document:

{
  "@context": {
    "list": {"@id": "http://example/list", "@container": "@list"}
  }
}

Could this be an incorrect expansion of the document, which instead should be the following?

{
  "http://example/list": {"@list": [{"@list": ["foo"]}, {"@list": ["bar"]}]}
}

Yes, you're correct. I fixed it in the WG version of the test suite. If you like, you can update this, but I'm going to work on redirecting the tests to w3c.github.io/json-ld-api/tests.

Great, thanks!

In that case I don't see the need anymore to update the test here.
