Subject RE: Question related derivative code based on our Apache licensed code
Date Tue, 17 Jan 2012 01:46:08 GMT
I see no effort to weaken affiliation with LibreOffice.  I see prominent affiliation by participants
on Apache OpenOffice with LibreOffice (and consequently vice versa).  That there are individuals
on each project that find cooperation unappealing has not hindered cross-contribution.
Perhaps one source of misunderstanding at AOO is the notion that a contribution to Apache
OpenOffice is transitively available to LibreOffice by virtue of ALv2.  As Michael Meeks remarks,
it is not quite that easy (but not impossible, as is the case for the reverse direction).
 It does require a level of attribution and preservation of provenance that tends to be disdained
among some open-source communities.  ("Relicensing" is an unfortunate myth.  But combination
into an other-licensed work is not and it is completely possible with ALv2-licensed material.)

In the case of modest patches, I think it is a matter of where the contributor who has the
rights to do so actually contributes the patch.  It is strange to affirm any license other
than that used by the project the contribution is made to.  It is also awkward to submit a
patch in more than one place. 

Contributing to a shared place with it being clear there are no additional strings attached
gets around all of this.  That could happen when a patch is submitted without additional ceremony
to a commonly-subscribed security list, for example.  And, in that case, a multi-license declaration
might work more easily too.

No, Joe, I spotted that, but thanks for your concern.  

This meme only arises in Rob's communications in connection with LibreOffice contributors
being encouraged to join Apache. Licensing is as much a community choice as it is a mechanical
matter, and as a member of both communities I have observed that the apparent encouragement
to weaken affiliation with LibreOffice diminishes Apache's credibility among many LibreOffice
community members. 

My comment to Rob was by way of a reminder that it would be better to stop acting divisively
like this. My apologies if this brevity was confusing.
