Yes, this is the place to propose extensions, new types, or feedback from deployment experience with the existing vocabulary. We don't yet have a super-polished process for this, and the general model is certainly closer to 'discussion forum' than 'formal standardisation'; but however it works, this is the place. As a bit more context: I recently started a contract with Google, working solely in support of the Schema.org initiative. There are others from the Schema.org partners on this list, however unlike me they also are busy with responsibilities for products and services. My role in part is to help bridge between this discussion and feedback group, and the teams from the Schema.org sponsors. The charter, wiki and issue tracker http://www.w3.org/2001/sw/interest/webschema.html http://www.w3.org/wiki/WebSchemas http://www.w3.org/2011/webschema/track/ recently set up here are tools towards that end. This forum is also designed as a meeting place for participants from other initiatives - e.g. Dublin Core, Good Relations and so on. So one route towards getting Schema.org extended in some area is to identify possible collaborations and opportunities for vocabulary re-use. The integration of rNews vocabulary into Schema.org (see http://www.iptc.org/site/Home/Media_Releases/schema.org_adopts_IPTC's_rNews_for_news_markup ) is a good example of that. I will do doing my best to keep the Wiki and issue tracker in a healthy state, with summaries of proposals, use cases and examples for extension areas. The Wiki itself is open to public participation (though you'll need to sign up for a W3C account). Anyone proposing vocabulary for Schema.org specifically should be prepared for their contributions to be published there under Schema.org's terms (see http://schema.org/docs/terms.html ); larger integration projects like the rNews example will need a simple written agreement on file. There's a lot to be learnt here from the habits of the microformats community, and you'll find links to their approach and more from a draft 'process' sketch I've posted at http://www.w3.org/wiki/SchemaDotOrgProcess ... though note that the process there is not for the W3C group in its entirety, but more about the specific relationship between Schema.org and discussions here on the W3C list. I hope that helps. I realise there's more that could be said, but as a high-level sketch to get things moving. As I've pointed out a few times in specific threads, the central thing here is to remember that we are scoped to practical markup for real public-facing Web sites. As with all such data modeling, there is no single objective 'right way to do it', so it is worth stating design biases. An important one here is for markup simplicity, and for markup that fits the structure and content of a good number of existing useful Web sites. So rather than asking ourselves, "what is the 'best' ontology for cars/documents/TV/music/people/...", instead think in terms of sites, or categories of site, that describe such things... cheers, Dan
