Subject Re: Cocoon Sparql Transformer ? - Peruser 2.1.1 released to Sourceforge
Date Sat, 15 Mar 2008 18:30:53 GMT

My group has finally released Peruser 2.1.1, which includes features for

our work in this area can be complementary to other work in the Cocoon
community.  Does the idea
of a "peruser block" in the Cocoon distro make sense?  (Perhaps that's more
a topic for cocoon-dev).

A few months ago, we started this google group for general discussion of how
Cocoon fits with semantic
technology.   We thought this was wise, to avoid possibly drowning the
cocoon-users list in what
might become a busy topic with a limited constituency.   All are welcome to
join in there, but continuing
the discussion here on cocoon-users is also fine with me if it's OK with our
list moderators.
