[pax-logging] Is it OK to integrate BSD licensed bwaldvogel/log4j-systemd-journal-appender into pax logging?

[Michael Vorburger]

Hello Paxifians,

For https://issues.apache.org/jira/browse/KARAF-5275 for https://bugzilla.redhat.com/show_bug.cgi?id=1475951, a question:

Would it be OK to bundle the BSD licensed https://github.com/bwaldvogel/log4j-systemd-journal-appender into OPS4j Pax Logging?

I'm willing to put together a pull request proposing this, but wanted to first double check before with you guys if anyone here had any reservations on the license side... is embedding a BSD licensed library into a ASL licensed project cool?

Tx,

M.

Hi

BSD is a cat B but not cat X so yes it's possible. No worries.

Michael,

(Re-sending from my subscribed address.)

The canonical source of information regarding licence categories (A, B, and
X) from the ASF’s point of view is https://www.apache.org/legal/resolved.html
— that will answer similar questions for you in future. Note that licence
categorisation can evolve, see e.g. the JSON licence.

Regards,

Stephen

One of the Flume appenders in Log4j2 requires BerkeleyDB which has a similar annoying license.

Now I don't know of any licensing guidelines for ops4j specifically, but following the ASF's guidelines seems to make a lot of sense.

As most of Pax * projects are used in Apache project (like Apache Karaf), I would follow the ASF guidelines, yes.
