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 linked-art/linked.art#235 (comment). 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.
