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.
