Hi Dan,
Thanks for summarizing this. Two suggestions:

1. Instead of samePropertyAs: rdf:type, use owl:equivalentProperty if you want to express how the additional type information can be mapped into an RDF world.

2. Add a link to the thread in the W3C archive so that the full details of the discussions are easy to reach:

By the way, the original proposal now being favored was already described in my post

    http://lists.w3.org/Archives/Public/public-html-data-tf/2011Oct/0088.html

and presented at the schema.org Workshop back in September 2011 (slide 16):

Best

Martin
