Open Annotation Data Model and TEI

Philipp (Trier): During our telephone conference I get to know Open Annotation Data Model because our guest from the University of Cologne, who is working on a tool for the semantic annotation of images, asked us about it. For our metadata about medieval books we use a mySQL database and XML according to the TEI. Lots of these information refer to the codex and not to single pages or parts of pages. But the software that we develop in our project should recognize defined layout features on digital images and it might be interesting to store these results as annotations on the image as well as in the metadata in our XML files. The question arises whether it is possible to map these two approaches without loss.
