Jeni,

Hmmm, I'm a bit unsure if you're referring to the examples/ section of  
Schema.RDFS.org [1] or to the gateway [2] which is based on Ed  
Summers' rdflib parser plug-in for microdata [3] or, maybe, to the set  
of scraper scripts [4] we use to generate all kinds of structured data  
(RDF, CSV, JSON) from the Schema.org HTML pages?

IIRC, we have a Schema.org-specific mapping in place, but I feel  
Richard is more competent to answer this one - Richard?
Related (because of organisational proximity) is the any23 issue 173  
[5] - note that any23 is used in Sindice and has hence also some  
potential effect on the ecosystem.

HTH ... ?

Cheers,
