This is excellent news.

Thanks!  That really clarifies things and will assist in getting a validator integrated.

In addition I've recently published LRMI content for Khan Academy into Learning Registry using a Schema.org translated to JSON using the transformation described in HTML Microdata (http://www.w3.org/html/wg/drafts/microdata/master/#json) as a purely portable and machine readable version of schema.org.

Some of that published content can be seen here:
http://node01.public.learningregistry.net/harvest/listrecords?from=2013-03-18T21:02:25Z&until=2013-03-18T21:14:59Z

For those not familiar with Learning Registry, the metadata content that is encoded in application/microdata+json is located in:

	response_object.listrecords[index].resource_data.resource_data
