16:18:52 <manu> We say the following in the JSON-LD specification: Even though JSON-LD serializes RDF datasets, it can also be used as a RDF graph source. In that case, a consumer must only use the default graph and ignore all named graphs. This allows servers to expose data in, e.g., both Turtle and JSON-LD using content negotiation.
