I’d sent you a separate note on your metadata problem, but while I’m thinking about the broader issues, one interesting person who does immediately come to mind (thought not a specialist in microformats) is Kris Shaffer, who is a digital humanist, data scientist, and a digital media specialist. Recently he was a scholar with the Division of Teaching and Learning Technologies at University of Mary Washington before heading into the private sector. I suspect he may have some interest as well as relevant experience for problems like this and could point you in some interesting directions.
Congratulations on the new website! Glad to see you’ve got a bigger presence for longer form thoughts that I can follow.
