Greetings David:

This is an official RDF working group response to your message
http://lists.w3.org/Archives/Public/public-rdf-comments/2013Oct/0010.html
on Section 5.2, Intuitive Summary, of the RDF 1.1 Semantics document.
The Working Group thanks you for your concerns on this aspect of the RDF
recommendations, which have been tracked as ISSUE-149.

Section 5.2 is an informative section and was only put in as an short,
easier-to-understand gloss of some of the the preceeding more-formal
section.  Both your comment and the ensuing discussion have made it clear
that the section is not achieving its purpose.  As there appears to be no
consensus on what changes, if any, should be made to the section, it is the
intent of the working group to just remove the entire section.

Could you please respond to public-rdf-comments@w3.org as to whether
removing this non-normative, non-formal section would satisfactorily address
your concern?  If you are satisfied, then the section will be removed from
the document.

Peter F. Patel-Schneider
for the W3C RDF WG
