My project is InfoML (http://infoml.org/), a proposed standard for storing "chunks" of (human-readable) text and annotating it with various useful metadata, including tags and bibliographic information. I hope there will eventually be a community of developers who will find InfoML useful and will build a variety of software tools for manipulating data stored in this format.

I think a microformat schema or schemas would be more beneficial for this kind of data.
