Re: [geclipse-dev] Gria Information Gathered

[Harald Kornmayer <harald.kornmayer@xxxxxxxxxxxx>]

Hi Nick, hi all 

What you find out is useful and can be used, but anyhow, that are just
the services of "local" GRIA services. So the user can find the data and
the application services if he/she knows the computer where the services
are running. But a Grid should consist of many distributed site with
services. 

So from my point it would be nice anyhow to have a list of the
distributed services called a registry? Such a service registry can just
be viewed as a "bookmark" to the services as the bookmarks in browsers. 

My questions: 
How do you plan to sort the distributed services in the InfoView? 
How do you get the "complete" list of available services at different
locations?

In my opinion, the statement "we do not need a registry service" is a
little bit to strong!

Cheers
Harald
