[Pgi-wg] PGI draft v0.40

[Balazs Konya]

Dear All,

As i promised on the last meeting, i started to go through the "PGI Execution 
Service Specification" draft and made numerous editorial changes. I 
accepted/rejected tracked changes, removed obsoleted sentences, inserted notes, 
fixed text here and there. I managed to complete only the Introduction, 
CreateValidatedActvity, CreateActivity operation sections. The modifications of 
the State model section made by Etienne were also processed. From now, i'll be 
doing editorial cleanup regularly.

Please find the new version here (v0.40):

As part of this work, i also started to collect "open questions" based on the 
yellow texts and notes in the draft (copied below). These issues have to be 
resolved during the calls.


bye,
Balazs





PGI open questions:
-------------------

1) SERVICE VECTOR LIMITS: work out the details of how vector limits of 
operations are published, decide upon the granularity of these limits (per 
portType, per operations, etc..). Define FAULT mechanism.

2) Which of the Execution portType operations are mandatory?
What about the CreateValidatedActivity?

3) Activity ID: any special requirement? Currently the specs only states
"service creates an instance of each activity that is identified by a global
unique ID assigned by the service"

How about UNICORE Gateway issue, Find out why that is required? maybe the 
address has to be there or the extension mechanism?

4) Finalize the holdpoint specification within job description

5) Decide how/if state changes are tightly coupled to operations, is it allowed
that an operation aggregates multiple state changes?

6) Elaborate on how data staging can be monitored via the state model.

7) Decide whether some kind of "LEASE" feature is to be introduced within 
Execution portType.
