Re: Call for comments on MAWG Terminology

Just one comment.
I think your distinction between resource and representation is not
the way in which the Web uses the word "resource". The term "resource"
is already defined in "URI" (unified resource identifier), so you
should not need to re-define it.

There is however always the possibility to open your own naming space
- in which case there is no need to be in sync with MF, since we are
in sync with URI.

Cheers,
Silvia.
