That would be a great project to get Oyranos' core in better shape.

Currently Oyranos is rather complex. The configuration parts are
exposed by a limited stable API and the object oriented stuff as used in 
kolor-manager and ICC Examin. The CMM related graph handling is interwoven 
with configuration constraints and the UI exposition through XFORMS[1]. So 
often enough APIs can not be exposed separately, say the CMM part for 
colour conversion or the named colour API, which have otherwise not 
changed much in recent months.


Oyranos has a small C code generator[2] for object oriented structures and 
belonging functions. I started to support spliting object code into 
public generic structures and a internal full blown object part. This 
could be used to generate most objects structures from scratch and port 
the actual functionality by copy and past. Adding missed tests for the 
ported APIs would be of good help through the process.
This would be a large part of the project and allow the profile, device 
configuration and possibly named colour APIs to become supportable in a 
stable API.
