Grant,

I'm originator of this thread and PostgreSQL is also a big user of the
Snowball project, so we also are very interested in the vital 
activity of the project. However, I see issue with license, which is
currently BSD and this allows us to use snowball in PostgreSQL (which
is also BSD licensed). Is't possible to preserve BSD license under
Apache Software Foundation ?

Another question is not about snowball compiler, but about specific
stemmers, which contributed by people. Are you willing also to
support this activity ?

I'm crossposting also to the -hackers discussion list of the PostgreSQL
project.

As I understand it, ASL 2 is incompatible with GPL 2, at least according to
the FSF.  This would be a showstopper problem for me.

Er, what does Postgres have that is covered by GPL2?

Where does GPL come into it?  (I hadn't seen that mentioned before for
either product.)

No, it would have to be ASL 2, but that is pretty similar to BSD, no?  
(caveat: IANAL)  i.e non-viral, free to use however you want, just  
don't take credit for it.  Everything I've read says the two are

ASF is all about community, so the community would be responsible for  
supporting the activity of the project.  Obviously, Dr. Porter and  
Richard would need to be involved, but one goal of the ASF is that any  
healthy project should be able to survive the loss of a committer.

The way the ASF works, people who contribute a lot would become  
committers, etc., so yeah, I think the answer is yes.  It is a fairly  
well defined process for doing this.  i.e. if you contribute a lot,  
the other committers would nominate you to become a committer.  You  
can read more about how the ASF works at www.apache.org/

HTH,
Grant

Richard is one of the developers of Snowball so he might want to keep
its license compatible with GPL2.

Moreover, Snowball is used by a lot of projects, and probably some of
them are GPL2.

Note that ASL2 is however compatible with GPL3.

Keep in mind that you're seeing some fraction of the discussion on
snowball-discuss (whatever is from people also subscribed to
pgsql-hackers; everything else is stuck in the moderation queue).
I would imagine the GPL complaint is from someone who's using the
snowball code in a GPL project.

However, from a Postgres point of view, I'm not sure that we'd be
totally happy with ASL either.  We'd certainly have to stop bundling
the snowball code in the Postgres distribution, as we do now.  Or more
likely, freeze it at the last BSD-licensed release.

I think cross posting has confused this thread - I was talking about
snowball not postgres.  I don't use postgres at all; in fact, I'm not sure
why this thread was copied to pgsql-hackers at all - sorry for the noise if
there wasn't a good reason.

What I mean is that I use snowball in a project which is GPL-2, and cannot
be relicensed, and snowball changing to ASL 2 would be a showstopper
problem for me for that reason.
