3D data model

[Igor Chilingarian]

Dear Francois,

For me the main idea is not to organize a group or sub-group, but just to know
the people interested in the topic and try to hear their opinions. I'm ready
to make a review of Characterization DM from the 3D point of view. We may
discuss on Thursday what should be the result (some document, some
corrections, or something else). See you soon.

With best regards,
						Igor
