My homepage at http://danbri.org/ is XHTML / RDFa and has data in RDFa 
attributes. I'd like to do this in HTML5 +RDFa instead, so I can take 
advantage of the other new features in HTML5. However the data is very 
much not private to the page, but designed to be used by a broad range 
of consumers. For example, Yahoo's SearchMonkey, or Google's Social 
Graph API. The use of RDF namespaces in that data indicates that we're 
using shared public schemas, rather than private islands of 
application-specific data.

Perhaps if the Web itself is considered an application, then this is 
"application-specific data".

cheers,

Dan
