A few major milestones have been achieved in the past week. Our best practices guide, weighing in at 33 pages in it’s v.5 version, is now available on the Resources page. If you have a question on markup methods for the accessibility metadata, this is the definitive resource. Questions or requests for clarification should go to our Google Group list, available on the Discuss page. I’ll note that the document is quite complete and extensive, but is in draft mode primarily because the specification to schema.org is still in draft.
As we get closer to our first real implementations and available data, we do have some live examples coming online. The first example, from Bookshare, can be seen on the live examples page.
