[ogsa-bes-wg] Create a revised BES spec draft that reflects the decisions of the July F2F mtg

[Ian Foster]

Marvin:

I've claimed the pen on the document, but have been finding it hard to find 
time to make a lot of progress. I will try to do some work on it tomorrow 
morning.

That said, I want to mention an important development that Dave Snelling 
may or may not have mentioned on calls. Dave argues that we can avoid the 
need for distinct renderings by defining our interfaces carefully. The 
basic idea, as I understand it, is that:

a) the "core interface" has the basic operations for creating jobs, 
modifying their status, etc., and an operation for grabbing all of the 
factory state;

b) then, if desired, a WSRF service (for example) can also implement the 
WS-ResourceProperties, WS-ResourceLifetime, WS-BaseNotification, operations;

c) while a WS-Resource service would implement the WS-Resource equivalents 
of those.

So we exploit the power of interface composition to avoid the need for 
separate bindings.

The only problematic issue, as I understand it, is that of faults. The 
question is how we render faults. The WSRF binding must (by the spec) use 
WS-BaseFaults. If we can all agree to use that, then we are ok. If not, 
then we still have problems.

Ian.
