Subject RE: Legal question about (re)licensing
Date Sun, 29 Apr 2012 15:48:55 GMT
To be precise, the practice is for new contributions to be dual licensed as LGPL and MPL by
the contributor.  It remains the case that the main code body is under LGPL3 with the usual
variations for third-party material incorporated in the release.

PS: Personally, I don't see any advantage to the MPL provision, since LGPL is not convertible
to MPL.  I think there is or was some TDF misunderstanding about the possibility of "relicensing."
 As far as I know, only the owner of copyright has a choice about licensing.  E.g., Oracle
licensed the code base that was under its copyright to Apache in a different
way than it had licensed to others.  That's separate from the general but narrow availability
of that code under the LGPL from both Sun and Oracle.  
    The license that code arrives into someone's hands under is the license that must be honored,
even for public-domain works (which require no license and will remain public-domain forever).
If a work is specifically multi-licensed, one can choose which one(s) to honor.

When LO says they are under MPL, I think they mean that only for new
contributions, where the contributor agreed to place their
contribution under MPL (or whatever).  The remainder of the code, the
original OOo code, is under LGPL.
