Re-post: Request JSON-LD with embedded or referenced context

Re-post as didn't seem to work the first time

> Greetings,

> Following on from a Twitter exchange with Manu, Markus and Gregg where I asked about best practices regarding embedding or referencing to a context in a JSON-LD document.
> I wondered if there is any way for a client to indicate a preference for embedded or referenced context when making a request?
>  
> Having read the IANA Considerations chapter of the JSON-LD recommendation [1] I'm none the wiser.

> Would it be useful to add more values for the profile parameter that would allow the client to indicate a preference:
> -    http://www.w3.org/ns/json-ld#embedded
> -    http://www.w3.org/ns/json-ld#referenced
>  
> These could either be used in combination with the URI http://www.w3.org/ns/json-ld#compacted, but just specifying either of these should be enough to infer that compacted form is preferred.   
>  
> Also when requesting compacted document form, how does a client indicate the context which should be used to compact the JSON-LD response?
>  
> I could imagine the URI of the context might be included in the list of URIs for the profile parameter, or perhaps supplied in a HTTP Link Header using the http://www.w3.org/ns/json-ld#context link relation.
> The latter is probably less ambiguous.
