Hi,
Anyone else implemented HTML5 Microdata [1] and/or Schema.org [2]?

I'm looking for examples of libraries, museums, archives, and
educational organizations that have implemented HTML5 Microdata and/or
Schema.org in any way. Even if you have just used it in a very limited
way on a site, I'd be interested in seeing it.

I have a short list right now that I've gleaned from various email
lists, and I have looked around Sindice and blekko's "grep the web"
[3] and found a few more. Anyone know of a way (other than doing my
own map-reduce job on the common crawl data [4]) to search for
embedded markup like this?

I'd like to see if there are more examples I could draw on for my
code4lib conference talk.

Thank you,

Jason
