+1.  Ok, so it seems we're all pretty much in agreement that metadata extraction and indexing should happen on the server side and not on the client.  As I said before, this is good. Simple clients, support for re-indexing, support for changes in indexing characteristics, and the ability to save the world from AIDS.

This puts a requirement on an efficient and portable serialisation format.  Again, +1 to starting with defining what we need.  Good start below, Sanne.

I'd add:

* Support for fast and easy translation to/from object model in high level language of choice (i.e., not manual parsing!  Maybe some form of tooling, like a Maven plugin, to generate "IDL"-esque format)
* Serialisation efficiency (size and speed) should be considered

And in addition, I'd also list out existing technologies that fulfil some or all of these requirements that we can consider, look at extending, etc.
