[Opensim-dev] LL Viewer code license change

Tue Aug 17 13:43:59 UTC 2010

If I heard Oz and Esbee  correctly, the whole of the viewer, with the
exception of the proprietary libs they use (which I htink is the KDU
jpeg2000 stuff and one or two media codecs at this point) go to LGPL. You
can't mix LGPL and GPL deeply, as Adam's pointed out. I'm not enough of a
LGPL wonk to know exactly where that takes things. I'd think the question
is "does it change the dynamic on "derivative work" I know being LGPL means
that one could link bits direclty into OpenSim legally. That's
straightforward. What's less obvious is whether reading the LGPL code
causes the same issues that
reading GPL code causes. They did point out that they still insist on the
contribution agreement, and that the contribution agreement was why they
could shift licenses.

It’ll have to be all LGPL if parts of it are – since the GPL wont accept
redistribution of a mix of LGPL and GPL – only pure GPL.

Check the post on sldev about it – it looks to me from that one that the
intention is for it all to be LGPL.

 As regards to OpenSim contributions, I doubt that the viewer license
 change to LGPL will make any difference.  LGPL just
 makes it possible to link non-GPL code to the viewer code.  The viewer co
de itself is still virally licensed.
Justin, where did you get this information?  Its not the way it was
presented at SLCC (I watched the entire announcement and read the postings
afterwards by LL).  So, its not the way I read it, but we need to check.
They even amended the licence from GPL to LGPL for a lot of the top level
parts of the viewer source code as I examined some of the key commitdiffs.

"for a lot of the top level parts"? Not the entire code base? I'm curious
which parts are now LGPL and which are not, and if not, what license they
are under?
