Hi,
I still think it would be good to factor it out.. there aren't enought good
java based spamfilter libraries out there...
I think many developers would us our work if it would be possible and
visible to them.
Cheers,
Norman

on balance, it's important to choose the right granularity. probably
better to pick a cohesive topic. i'm very interested in using machine
learning with mail. if anyone starts to be become interested in
developing any more machine learning mailets, we can factor it out at
that stage.

the code has very little visibility within James. a mini-site would
have more visibility.
i agree with norman's point that the bayesian code is potentially
reusable if it were in a separate library

i like micro-libraries :-)
they've also proved very successful over the years

there are some interesting stuff which could be done using machine
learning and mail. i can think of a few cool SoC projects based around
this.
but i agree that the effect is only worthwhile if there are people
interested in this area of james

IIRC the avalon code is used for data access. it would be easy to
replace this with JPA (say) or JCR.

Unless there is someone willing to work on that code I think it is bad
to move it out.
Otherwise we'll end up with a microlibrary for the ClamAVScanner, for
the SpamAssassinInvoker, for the NetworkMatcher and so on.
You proved that you take care of releasing what you proposed to extract,
so I believe in you if you want to follow this path.
We have
org.apache.james.util.BayesianAnalyzer
org.apache.james.util.JDBCBayesianAnalyzer
org.apache.james.transport.mailets.BayesianAnalysis
org.apache.james.transport.mailets.BayesianAnalysisFeeder
Only 4 classes, and they are bound to
excalibur/cornerstone/avalon-framework...
If you're willing to refactor them to remove the avalon/excalibur
dependencies then maybe they can live alone, otherwise I hardly see any
advantage in moving it out.
