[kepler-users] Kepler, adding composite actors?

[Matt Jones]

Lots of us would like to have this working, and it is right on the top
of the list for some of the SEEK developers.  But it is complicated and
we are rearchitecting the system to support archive file formats that
should make it far easier for us to add in new actors or workflows that
are both locally and remotely stored to the system.  Both the KSW file
archive work and the Kepler Object Manager work will be involved in the
final system.  These are described here:

http://kepler-project.org/Wiki.jsp?page=HotTopics

If you really want this work to go faster, we would welcome help on the
development work.  Let me know if you have cycles to contribute.  Thanks!
