Dear Felix, all,
   sorry for late reply and I'd like to draw your attention to the  
MPEG Extensible Middleware (MXM) which aims to define APIs enabling  
applications to access standard multimedia technologies (including  
metadata). Note that within this standard we will also produce  
reference software which will be available under an open source  
license. Requirements, working drafts, and a proposal for the MXM  
public license is publicly available under [1].

You may find some parts thereof interesting, especially the APIs  
related to metadata for image, audio, video, and content in general.  
We may also collaborate (e.g., via liaisons) in order to stay  
compatible the one way or the other.

Thank you.
Best regards,
  -Christian
