Re: Is this valid JSON-LD?

Ah! I did not realize this.

Here is how I hit this. I do an RDFa->JSON-LD conversion (via RDFLib as an intermediate RDF toolkit), and I would like the beautify the output. If the user in RDFa does


<span rel="http://www.ex.org/prop" resource="http://a.b.c"/>
<span rel="http://www.ex.org/prop" resource="http://p.q.r"/>

and there are no prefixes (or vocab) defined in the original source.

A simple json-ld is of course

{
  "http://www.ex.org/prop" { "@id" : "http://a.b.c" } ,
  "http://www.ex.org/prop" { "@id" : "http://p.q.r" } 
}

but, to make it cleaner, it would be nice if I could say

{
  "@context" {
     "http://www.ex.org/prop" : { "@type" : "@id" }
  }
  "http://www.ex.org/prop"  : "http://a.b.c" ,
  "http://www.ex.org/prop"  : "http://p.q.r"
}
 
Which would require to have the URI as a key. 

Bottom line: I am very much in favour allowing this.
