Congratulations on the new website! Glad to see you’ve got a bigger presence for longer form thoughts that I can follow.
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.
