[kepler-dev] Got web UI?

[Timothy McPhillips]

Hi Paul,

This sounds really promising, and I like being able to read a summary  
of this kind when evaluating a system.

We have started putting together a Kepler Web User Interface Interest  
Group on the new Kepler developers' site. We plan to put our more  
detailed discussions about web interfaces for Kepler in the interest  
group forum, post descriptions of our various needs and designs to  
the interest group pages, etc.

At the Santa Barbara meeting in July, four of us drafted a document  
outlining our understanding of the needs for web-based UIs for  
Kepler, highlighting the diversity of the requirements in different  
projects, and proposing we collectively focus on developing a common  
"job manager" that sounds very much like the one you describe.

What would you think of using the interest group pages and forum as  
the venue for sharing more details about your work, and for chatting  
about the requirements in other project?

Cheers,

Tim

P.S.  The user account and password for editing the Plone site is the  
same as for svn repository write access.  Please let us know if you  
do not have an account.  Thank you!
