[kepler-dev] Kepler Web UI?

Paul --

There are some efforts that I know of working on this.

1) GEON: created a system for selecting, paramaterizing, and running 
Kepler workflows or LIDAR data processing inside a portlet.  As far as I 
know the code is not checked into the Kepler cvs.  The developer on 
this, Efrat Frank, has moved on, but her colleague Ilkay Altintas 
(altintas at sdsc.edu) at SDSC may be able to help locate the work.

2) SanParks: this project at NCEAS is focused on making workflows that 
scientists create available to managers who need to run the workflows 
and inspect the results.  The project has not yet begun development on 
this task, but we intend to build a general framework that can be 
deployed with kepler and that is broadly usable by many projects for 
browsing and executing workflows and inspecting the results via the web. 
We will likely build upon the work already done in archiving workflows 
and searching for them on the web in the Kepler Component Library.
Contact me for more information.

3) Chip-chip: this project at UC Davis is creating a web-based 
environment for scientists to use to run experiments using Kepler 
workflows.  They have described their architecture as one in which 
developers and domain programmers create workflows and workflow 
components that can be used by scientists to compose and execute 
workflows on the web.  I am unsure of the status of this project. 
Contact Shawn Bowers (bowers at ucdavis.edu) for more details.

4) Trivial cgi: Attached, I wrote a trivial CGI script in perl that 
demonstrates the ability to run a workflow (in this case, one that 
generates html output) and display the results on the web.  Proof of 
concept only -- we're not intending for this development to go anywhere 
(it was a 4 hour project).  I believe Josh Madin extended this to make 
the script a bit more general.

5) Others: this is a common question, so I'm sure there are other 
efforts along these lines.

Hope this helps,
