There is nothing to wordsmith, you poll even verifies my point.

Here's my point:

If the W3C's RDF group is to endorseJSON-LD as a recommended concrete 
syntax for RDF, then it is natural (and basic common sense) for said 
workgroup to define Linked Data using the bullet points outlined in 
TimBL's revised meme. Why would the RDF workgroup of the W3C do anything 


My point (above) doesn't mean that RDF and Linked Data are the same 
thing. It simply acknowledges the fact (the basis of your poll) that in 
the context of a W3C recommendation, from a W3C workgroup dedicated to 
RDF, the Linked Data aspects of the JSON-LD spec should be constructed 
in line with TimBL's revised meme.

My point *will never mean or imply* that you cannot produce Linked Data 
without RDF.

It makes absolutely no sense for the RDF workgroup of the W3C to endorse 
*any* standard that's inconsistent with its definition of RDF.

I desperately hope this sheds clarity on my position.

If anything, I should have brought attention to the fact that JSON-LD 
becoming an RDF workgroup recommendation isn't something (I for one) 
immediately honed into during my conversations about Linked Data in the 
context of JSON-LD's spec evolution.

If JSON-LD seeks official recommendation from the W3C's RDF working 
group, then it has to adhere to the minimum requirements sought by that 
group. Again, that's common sense.

What's outstanding at this point in time? Determination by the W3C's RDF 
working group as to what it deems to be normative re. Linked Data based 
on (or maybe not) TimBL's informative memes.
