Hi
It's a difference between inclusion, usage, and reference.
For instance, GPL license is a intrusive license. It means that any
software that use a code under GPL has to be itself under the GPL
license. That's why you can't use GPL in a Apache project. It's the case
for usage, inclusion or reference.
LGPL is a bit permissive in the cave of reference. LGPL is a Category X
for inclusion and usage. It means that it's not possible to use LGPL if
the project embeds some jar under LGPL, or ship some code (like
copy/paste) under LGPL. However, if you just reference the project
without embedding it, and it's an user action to actually download and
add the LGPL jar, it's fine.
Regarding your question:
1/ category A
2/ category A
3/ category A and B
4/ category A and B (and we have to "publish" the changes)
5/ all
6/ category A and B

Hi
I have some licensing questions.
I have found following page http://www.apache.org/legal/3party.html
which defines 3 categories of third party licenses. According to this
page LGPL v2.1 is category X, but further remark says, the
LGPL-v2.1-licensed work can be listed as system requirements but can not
be included by Apache products. I'm not good in licensing but I try to
understand it. Is the category of LGPL really B (and the page should be
corrected) or is the LGP category X. In the second case, can we still
list Hibernate in Karaf features (e.g. using the remark about listing of
system requirements)?
Assume following use cases of third-party work usage:
1. reference 3rd-party library as (maven) dependency and use the classes
in ASF code
2. reference 3rd-party library as (maven) dependency and use the classes
only in ASF configuration files (e.g. blueprint.xml)
3. include/copy some unmodified 3rd-party code (e.g. some classes) in
ASF project
4. include/copy some 3rd-party code (e.g. some classes) in ASF project
and modify it
5. list some 3rd-party libraries in Karaf features, but not include them
as binaries in one of the Karaf distributions
6. list some 3rd-party libraries in Karaf features, and include them as
binaries in one of the Karaf distributions in system repository
Could anybody please answer which of above points are allowed for
following 3rd-party works
a. category A as the whole category - I assume, all above use cases are
allowed in this category, is it ok?
b. category B as the whole category
c. category X as the whole category
d. LGPL
e. GPL
f. EPL
I have chosen Karaf as sample ASF project, but it could be any other ASF
project, e.g. ServiceMix or Aries
Do the rules from the page mentioned above apply only for ASF projects
or for any project licensed under Apache License?
Best regards
Krzysztof

LGPL is category B (not X), so we can reference it but not "include"
it: it's what we do.
FYI, in Karaf 3.0.0, I've already added a hibernate feature.

Though it's a very useful feature, I'm not sure if we can add it in
Karaf, as Hibernate is under LGPL license, can we?
