Question: @profile keyword to specify the profile of a JSON-LD file in its content

[ioggstream]

Question

I have to parse different kinds of JSON-LD content:
some are frame, others are framed, others are plain data files.

I see that I can use ; profile=... at content-negotiation time,
but I found no specific keyword I can use to distinguish files
by their content.

Is there a keyword for that?

If not, does it make sense to define a @profile keyword to
espress the specific jsonld profile inside the file?

Ex.1

"@profile": http://www.w3.org/ns/json-ld#frame
"@context": ...
"@explicit": true
name: {}

Ex.2

"@profile": http://www.w3.org/ns/json-ld#framed
"@context": ...
"@graph":
- name: Homer
- name: Marge

Have a nice day, R.

@ioggstream I converted this to a discussion since it's not a json-ld.org issue, per se. That said, it may be best to propose this on https://github.com/w3c/json-ld-syntax/ instead, so we can be sure it gets JSON-LD WG-level call time at some point.

The proposal is interesting and the problem space is real--especially when frames can be confused with data and not even the file extension provides differentiation.

Happy to continue discussing it here, but feel free to open this as an issue on the JSON-LD Syntax repo, and we'll get the group to discuss it.

Cheers!
