Re: is linked data about RDF or EAV or just structured data?

Arnaud -

Yes. My concern is the requirement of an implementation to support 
RDF\XML as opposed to leaving serialization optional for the implementer 
so long as the data model is fully supported.  So, I guess I see that as 
a problem with submission if submission includes that a requirement for 
compliant implementation of the standard (which is not clear to me: I 
don't see the requirement of RDF/XML in the link you sent - but, if this 
is explicitly mentioned somewhere, I would appreciate a pointer and your 
patience along with it).

I have read the link you sent below as well as the three embedded links 
within it:

 1. /Linked Data Basic Profile 1.0
    <http://www.w3.org/Submission/2012/SUBM-ldbp-20120326/>/
 2. /Linked Data Basic Profile Use Cases and Requirements
    <http://www.w3.org/Submission/2012/SUBM-ldbpucr-20120326/>/
 3. /Linked Data Basic Profile 1.0 RDF Schema/
    <http://www.w3.org/Submission/2012/SUBM-ldbp-20120326/ldbp.rdf>

So, are you saying that the "submission" is set in stone in technical 
terms at this point?  If so, what is left to do for the WG?

Thanks.
