[DISCUSS] OK to start the process of bringing UIMA JMS to the UIMA project via a new software grant?

[Marshall Schor <ms...@schor.com>]

Some time ago, we started a thread on some UIMA extensions that made use
of JMS to support an alternative scale-out approach that moved much of
the middleware code out of UIMA itself and into other standard
middleware, such as Apache's ActiveMQ.  We posted some initial
documentation on what this was on the UIMA wiki at
http://cwiki.apache.org/UIMA/uimaasdoc.html

Is there any further discussion we need to do before starting the work
to bring this into the UIMA project under a specific software grant?

in that case I'm in favor of putting this code
in the sandbox and work out the kinks there.

Good points. 

I agree that it would be good to not burden users with things they don't
want/need.  The current packaging does add 2 jars, some docs, and some
scripts, but not the dependencies (like ActiveMQ or Spring).  We have a
special "run-this-to-download-other-needed-dependencies" script that
users run that gets these - it depends on "Ant", though, and because of
this, we do bundle Ant (in the current packaging). 

I think the packaging(s) of this are up for re-do, as part of the move
to Apache.  We could consider *additional* packagings that bundled these
dependencies, as well.  We could consider packagings that strip out
other things users don't want.  So, over time, our download site could
have a set of packages and users could download just what they wanted,
or maybe some other approach based on other Apache tooling could be used
to help us build a variety of packagings.

Re: JMS APIs and licensing:  I see in the mail archives that questions
around JMS licensing have come up before.  ActiveMQ, in particular, an
Apache project, makes use of JMS, and in fact, our imports of things
like the API type "javax.jms.Connection" come from the jar:
apache-activemq-4.1.1.jar.

These kinds of issues are important, and are usually worked out by the
community in the incubator, after receiving the software, prior to the
first "release".

My only concern is that I don't want to burden the core
distribution with a) code that most people don't need
and b) dependencies this code has.  What dependencies are
there?  Are you thinking of creating a separate
distribution with a bundled ActiveMQ?  What about the
JMS APIs, what license are they under?  Any other licensing
issues?
