Re: Linked Data Aspects of R2RML

Juan,

Good question, but one thing after the other :)

In the same vein as for the relational aspects of R2RML (as discussed during
our last telco), we are starting out with a quite abstract view on the
Linked Data aspects, trying to pin down what the charter really means (well,
actually how we understand/interpret it).

IMHO it's way to early to discuss implementation details, hence, please, all
WG members, refrain from diving into this for now, if you can ;)

Two things are important ATM: looking at [1] and see if one agrees with the
MUSTs/SHOULDs that are there, and add requirements or detail out in case I
missed out something.

Cheers,
      Michael
