[kepler-dev] Weka actors - experimental release

[Matt Jones]

Peter,

That's very exciting that you've done all of that with Weka.  It seems like
a tool that could be very useful across a number of disciplines.

One thing we've been working on is a new framework for creating a more
modular system for designing and packaging Kepler extensions.  One of our
goals is explicitly this use case -- to ship a set of actors and their jar
dependencies that can be loaded at runtime into Kepler and not have any
namespace or jar versioning conflicts.  We're currently experimenting with
this system and I was wondering if you'd be willing to let us (and help us)
package your Weka actors as an extension that could be used in this new
Kepler framework as it evolves.  We'd also welcome your commentary on what
would make for a good system for developing actors and packaging them
separately from the Kepler kernel. What do you think?  If you like this
idea, we could create a new extension area for the weka actors in the Kepler
SVN tree and then work on the packaging needed to make this into a
standalone extension.

Regards,
Matt
