Hello Kai-Uwe and Richard,
Thanks for your efforts for making ICC-technology and sets of standard 
ICC-profiles part of LINUX distributions.
I agree with Kai-Uwe, that it is necessary for the user to get an 
information vaild information, where the profiles have been originated.

I will start at the openICC wiki a page about profile packages, standard 
characterization-data for CMYK-profiles and licence issues. Please feel 
free to correct me, as i´m not a developer nor and open source licence 
specialist.

One question;
Is there any technical issue which have to be solved to synchronize the 
activitities of Oyranos and "share/color/profiles" ?

best regards
Jan-Peter
