[Content-in-RDF] Content Class

Dear ERT WG,

Please find below a description of the "Content Class issue" [1]. Feel 
free to comment in advance of the meeting.

Original comment by Robert Sanderson:

Initial response by Johannes Koch:
  - <http://lists.w3.org/Archives/Public/public-wai-ert/2010Jun/0001.html>


Essence of the comment:
  - use "dct:isFormatOf" and "dc:hasFormat" rather than "rdf:about" and 
"dct:source" to express relationships between content representations 
and between the original source


Following that suggestion, RDF code that currently looks like this:

[[
<cnt:ContentAsBase64 rdf:about="http://www.w3.org/Icons/w3c_home.png">
   <cnt:bytes>77+9UE5HDQoaCgAAAA1JSERSAAAASAAAADAIAwAAAO+{...}</cnt:bytes>
</cnt:ContentAsBase64>
]]

Would then look like this:

[[
<cnt:ContentAsBase64 rdf:ID="optinallyGeneratedID">
   <cnt:bytes>77+9UE5HDQoaCgAAAA1JSERSAAAASAAAADAIAwAAAO+{...}</cnt:bytes>
   <dct:isFormatOf rdf:resource="http://www.w3.org/Icons/w3c_home.png"/>
</cnt:ContentAsBase64>
]]


Proposed resolution:
  - accept these changes


Thoughts?


Regards,
   Shadi
