I think its more accurate to describe it as a particular
configuration of OpenACS, standard packages like forums
and file-storage plus some things which are
more suited to collaboration in a work environment.
In reality though it has not matured anywhere near as
much as dotLRN. We are getting there though. Jade Rubick
just committed a release version of project manager, logger
is a useful app, I am working on knowledge management, and
there are a host of other things which have come along
since dotWRK was proposed.
The piece we need is the thing that pulls it all together --
a portalized install of these packages and some tools to
better admin an intranet type portal. dotLRN could be adapted to do that although it's not clear to me at least
if that would be the best approach.
