[kepler-dev] Kepler user interface + relation to Recito

[Matthew Jones]

Hi Tim,

We have met the Recito developers at last year's miniconference, but we 
were not involved in what they did.  Our plans under Kepler/CORE for a 
new UI are more centered around a clean messaging API separating the 
user interface from the execution engine.  We are motivated by some use 
cases having to do with long-running workflows: the need for workflows 
to be able to be executed on various machines, the need to be able to 
launch the GUI to start a job, quit the UI but keep the workflows 
running in the background (we call it "detached execution") and then 
reconnect the UI later to monitor progress, and the desire to support 
multiple different UI clients (e.g., Vergil, eclipse-based, and web-based).

As Kepler/CORE is just starting, we have not yet collected requirements 
nor designed the API.  This would be done in conjunction with the 
community to try to determine what architecture would serve us best. 
Many people have spoken of an Eclipse UI, and so I think that would be 
high on the list of client environments that we would want to support, 
although it would be a lot of work to develop a new UI from scratch, so 
I'm not sure whether that would happen in the first pass -- more likely 
a refactoring of the current engine/vergil to make it so that they are 
better separated, allowing groups like the Recito team the ability to 
utilize the new messaging API in their eclipse client.
