I notice they adopt the idea of  "global attributes" -- attributes that can appear on any element. HTML5 and Atom also do this, so I think we're in good company doing the same. I'm working on some examples tonight...

Ok, I should have been clearer. So Schema.org (which I'm now working
on btw) defines a vocabulary in terms of classes and properties, and
then expresses those in HTML5's Microdata syntax. It can also be
expressed in RDFa. So the distinction here is between the 'domain
modelling' aspect, versus the work of figuring out how to carry this
data in an HTML-based notation.

So I guess I'm suggesting two things:

 - consider the same division of labour: define classes and
properties, without the same spec saying exactly how those are encoded
in HTML. You can rely on other specs for that, increasingly. (RDFa,
Microdata, ...).

 - consider the specific vocabulary of the Schema.org project, which
has currently got a lot of coverage for e.g. describing local
businesses and services, and perhaps we can identify mappings or
alignments there.
