[Joelib-help] Differences/similarities between CDK, JOElib, Octet, Jmol, Jchempaint, Structure

[Ola S. <ola...@lc...>]

Hello,

I am a little confused and don't know how these projects overlap and
their licenses.

CDK		LGPL
JOElib		GPL
Octet		LGPL
Jmol		LGPL
Jchempaint	GPL
Structure	LGPL

1) Have I understood the licenses above correctly? On some SF pages
(joelib & jchempaint) it says GPL or LGPL. What does that mean? May I
choose?

2) How much do CDK and JOElib overlap? I know you can use them together,
what are the benefits of this? Descriptors? Will descriptors not be
implemented in CDK?

3) What does Octet add to this mix (except that it's LGPL and JOElib is
not)? Can it be used with CDK? Overlap? Are the projects competing
against each other?

4) What does the Structure project add to all this (except that it's
built on Octet and LGPL)? The homepage says they are working on SDG,
isn't that already present in CDK? Doesn't JchemPaint do the same thing
as Structure?

I am posting this question in the CDK, Octet and JOElib mailinglists in
order to get more extensive information.

Best regards,

   .../Ola Spjuth
