[ogsa-wg] OGSA WSRF BP 1.0 Editor submission final call

[Djaoui, A (Abdeslem)]

Thanks for that Dave, it might be useful if we put a template together and ask different projects to fill it in.
I will circulate a draft ASAP.

Abdeslem,

To get you started:

Registry services in Production Unicore are integrated (the Grid fabric  
populates it rather than allowing registration). The registry of  
available resources, software, system load, and other services (such as  
brokers) are may available to clients on request. Most of this  
information is static and clients may choose to cache it. Most clients  
today cache it for the time they run and then refresh it when the start  
up. The Intel client allows manual refresh. Each registry is maintained  
by the sites, i.e. there is no central regisrty. However, the  
University of Manchester's Resource Broker I believe caches information  
from several sites to facilitate "Candidate Set Generation". Access to  
all this information is subject to authorization, e.g. non-public  
registry.

There has been some concern that the registry is an "all or nothing"  
implementation without a search facility causes an excessive load on  
server to client communication, but we have never had feedback from  
this issue.

There is a separate mechanism for registering jobs. By default, users  
see their own root jobs at the site where they were consigned. Sub-jobs  
at each site are only visible optionally - not supported by most  
clients today. There is a admin role that allows administrators to see  
jobs at a remote site.

In the prototype Unicore/GS, built on WSRF, the registry is still in  
the planning stages. It is expected that all the above information,  
which is already available as Resource Properties of the "Atomic  
Services" (the Unicore dual to GRAM, RFT, etc.) will be available also  
through a Service Group based registry in the near term.

We have not studied the possibility of a UDDI registry since the OGSI  
days. There may be fresh possibilities there.
