Putting the collection in context, you might have something like the following: { “@id”: “/alice”, “@type”: “Person”, “name”: “Alice”, “image”: "https://photos.example.me/saying-tofuuuu.png”, “hasCollection”: [{ “@id”: “/alice/friends”, “@type”: “Collection”, “manages”: {“property”: “knows”, “subject”: “/alice”} }] } As RDF, the two representations are semantically equivalent, and just from JSON-LD, if you flatten you’ll also coalesce the properties from both the outer- and inner- versions of alice to something like the following: [ { “@id”: “/alice”, “@type”: “Person”, “name”: “Alice”, “image”: "https://photos.example.me/saying-tofuuuu.png”, “hasCollection”: “/alice/friends” }, { “@id”: “/alice/friends”, “@type”: “Collection”, “manages”: “_:a” }, { “@id”: “_:a”, “property”: “knows”, “subject”: “/alice” } ] Gregg
