Jim,
Thanks for trying. It's probably a question for jsonld-java
directly. Jena is using jsonld-java and maybe the writer is being
too simplistic. If there improvements, then I'm very willing to
add them but when I tried various options, I didn't get nicer
output at the time. Maybe I was missing something as well.
I think it's all a little more complex than I initially realized, but
I know a bit more about JSON-LD now. :-) It seems like the way to
manipulate the structure of the produced JSON-LD is via framing:
http://json-ld.org/spec/latest/json-ld-framing/
It might be nice for Jena to allow the user to provide a frame when
writing JSON-LD.
Agreed.
The way to get information from the application is in Jena's "Context"
object (unrelated to JSON-LD's "@context"). The application is going to
have to be aware of JSON-LD details and maybe jsonld-java details but I
don't see that as avoidable.
Proposal:
Additional context keys:
jsonldContext
- value: the object expected for JsonLdProcessor.compact
jsonldFraming -
- value: the object expected for JsonLdProcessor.frame
if jsonldFraming is set
Then
JsonLdProcessor.frame
else
JsonLdProcessor.compact with jsonldContext.
Do you have an example (data, @context, frame) to use a development use
case?

However in my case I wanted some triples to be
serialized in the reverse direction, using the "@reverse" keyword (I
have lots of triples with different subjects but the same object).
But I don't think @reverse is handled yet in the framing algorithm:

Best regards, Jim
Thanks
Andy
