Error parsing linkedart context definition

[michielhildebrand]

Describe the bug We use Jena to parse RDF files, including jsonld. When loading the latest version of the linked art context definition in jsonld (https://linked.art/ns/v1/linked-art.json) Jena reports an error. According to the maintainers of the linked art context definition the jsonld is correct and is parsed by pyld, see https://github.com/linked-art/linked.art/issues/235#issuecomment-2184074817. The specific section of the jsonld document that triggers the error is.

"@context": {
   "@id": "crm:P177_assigned_property_of_type",
   "@type": "@vocab",
   "@context": {
       "part_of": {
           "@id": "crm:P46i_forms_part_of"
       }
   }
}

To Reproduce

curl -o linkart.json 'https://linked.art/ns/v1/linked-art.json'
cat linkart.json | ./ld-cli expand --ordered --pretty

Expected behavior JSONLD document should be parsed.

[michielhildebrand]

The problem was in the linked art context https://github.com/linked-art/linked.art/issues/235. The error message this library provided was correct. It appears to me that pyld is actually the one missing the error of KEYWORD_REDEFINITION within nested contexts.

@michielhildebrand great, thank you for sharing that.
