Hubert Figuiere has a name in unix photo world
http://www.teaser.fr/~hfiguiere/linux/digicam.html
so this can be a good approach. OTOH this group has to be somehow 
better than Dave Coffin. A lib that supports file decoding, 
demosaicing and metatag decoding as an open project would be cool 
but in a sense creating and supporting such a lib is a little bit 
out of digiKams scope, or? digiKam wants to use such a lib.

Browsing through
http://cvs.freedesktop.org/libopenraw/libopenraw
this seems to be a one person project and there is no usable code. 
The problem is, when Dave Coffin does not support such a lib you 
have to adjust/recreate the lib again and again with every 
release of a new dcraw.c. 

Maybe a better alternative can be a KDE wrapper for raw handling.
That way we can collect all the stuff out there now, can use our 
own data types, can integrate I18n and if there is a better lib 
someday we only have to adjust the wrapper(?)

I dont think this project has usable code now - maybe in months.
