Re: [wsrf] Some Thoughts on WSRF61: WS-RF Primer/App Note/Usage Notes

[Ian Robinson <ian_robinson@uk.ibm.com>]

Alan, I think you have a pretty good initial set of items for
consideration. My comments:


Rather than "Definitions of various terms: WS Resource, Implied Resource
Pattern, Factory Pattern, etc (we can extract information from the two
whitepapers (The WS-Resource Framework and Modelling Stateful Resources
with Web Services)" we should use the material from the new normative spec
(that we kicked off at the last F2F). These definitions need to be part of
the normative specs.


For use cases, the WS-RP use-cases that Rich talked about are also valuable
(ie modelling portlets as WS-Resources)>

Following our f2f meeting of July 27-28, we decided it would be a good idea
to write a non normative document on how to use the WS-RF family of specs.
We were not sure what to call it: Primer/App Note/Usage Notes/ Best
Practices document. For now, I will refer to it as "App Note." Brian was
good enough to add this to the issues list as WSRF61 and I am responsible
for this issue.


While I volunteered to work on the document and believe it is quite
important, I am not funded for this activity.  Hence, the time I can spend
on it is somewhat limited.   The purpose of this mail is to stimulate
interest in the document and solicit others to work on it with me.


In my opinion we need to provide the following content in the App Note
document:


-Overview of the WS-RF specs: WS-RP, WS-RL, WS-BF, WS-SG, WS-Renewable
References


(suggest one or two paragraphs for each spec description)


-Potential applications, e.g. examples of web services that contain
stateful resources (behind the WS interface), Grid Infrastructure layer
(along with WS-DM and WS-Notification specs), other WS specs (e.g. WSDM,
WS-Notification) that might make use of WSRF specs


-Definitions of various terms: WS Resource, Implied Resource Pattern,
Factory Pattern, etc (we can extract information from the two whitepapers (
The WS-Resource Framework and Modelling Stateful Resources with Web
Services)


-How the WS RF specs compose, i.e. are used together (including any
dependencies and interactions).


-Best Practices: clarification of nillable properties* and other items,
interpretation of fault messages and potential recovery options, policy
issues


-Any issues from the WSRF issues list that we feel is implementation
dependent (and therefore non normative/ not subject to standardization)


-How WS-RF specs could be used with WS-Notification specs (as per Peter
Niblett's presentation to both TCs at f2f meeting)


-How WS-DM specs (MUWS and MOWS) make use of WS-RF specs (input from WSDM
TC would be appreciated).


-How WS-RF specs could make use of WS-Security and WS-Reliable Messaging/
WS Reliability


----------------------------------------------------------------------------------------------------------------------------------------------------------------------------


*  We specifically stated that Issue WSRF48: Specify behavior of nillable
properties was a candidate for the App Note/Primer. "This should be
clarified or described as a best practice in the Primer, should we decide
to write a Primer."



Any comments, suggestions, ideas?
