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 mapping demand some tricky alignment like creating bnodes for 
Adresses
  - the RDFa code must remain simple

The idea is to just capture the voc they use with their semantics and 
then have the mapping and translation done through rules.
e.g. have an N3 rule transfrom the ogp "keyword types"  into URIs
e.g. have a rule 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 :
