You could find at http://mods-fr.sourceforge.net the MODS UNofficial Web
Site in french.
It contain the UNIMARC2MODS stylesheet and french forum about MODS.
It could contain in the future more french translations of the MODS
I hope that a lot french speaking people and UNIMARC users will use MODS.
This site contain an CVS tree.
So it could be the "open-source-like environment where everyone can
contribute "code" to the
structure" as Karen suggest.
I didn't already made an announce to the french librarian/xml community.
Maybe you (Network Development and MARC Standards Office staff ?) could have
some comments about this initiative.
