Dan,

Your work is included and I just pasted an new version.
I keep using etherpad because it is easier for everyone to participate.
http://etherpad.com/ogp-rdfa

The idea behind this new version is that we don't make direct mappings as :
  - most mappings demand some tricky alignment like creating bnodes for 
Adresses or Objects
  - the RDFa code must remain very very simple

The idea is to just capture the voc they use with their semantics and 
then have the mapping and translation done through rules (N3 rules, 
SPARQL Construct, RIF etc.)
e.g. have a rule to transfrom the ogp "keyword types"  into URIs
e.g. have a rule to create a resource for the page and another one for 
the object
etc.

Feedback is more than welcome.

Cheers,

For the archives the current version is :
