This is a very nice initial set of use cases for web services
(12.1 thru 12.9). 

12.7 will need to be fleshed out in context of web services
in some cases. Wherever, we can cross reference relevant 
use cases already identified in other related specifications
or initiatives would obviously be useful. 

If we are going to include in 12.7 OMG, we should consider 
including J2EE and .NET since these are commonly used
deployment environments although I believe deployment 
environment can be discussed in context of platform 
independence and interoperability requirements. 

How different web services features manifest themselves in 
some of these use cases will obviously need to be
discussed as part of validating requirements...

Subject: DAG0012 Use Cases


<RemovesChairHat>

I haven't seen anything on the list for DAG0012, so I'll take
a stab.

The current goal draft reads:

DAG0012 - identify or create the use cases that validate the 
requirements and the web services architecture and illustrate the 
benefits of web services

Aside from some gramatical nits, it seems pretty straight-forward
and quite reasonable and uncontroversial (IMHO).

Suggested tweaks:

DAG0012 - identify and/or create a comprehensive set of use cases that:
- validate the WG's requirements and the web services reference
   architecture, and
- illustrate the benefits of web services

As for CSF's for this goal:

DAG0012.1 must include for 'simple' web service use case such as the
infamous 'stockQuote' web service

DAG0012.2 must include e-commerce use case(s) such as purchase of
books through an e-tail portal such as Amazon.com or bn.com

DAG0012.3 must include b2b use case(s) such as supply-chain automation
between business partners. This should include some provision for
collaborative, choreographed flow of messages between partners

DAG0012.4 must include EAI use case(s) such as in the case of ERP
integration

DAG0012.5 must include portal content aggregation use case

DAG0012.6 must include REST-compatible use case(s)

DAG0012.7 should involve harvesting of use cases from external
(to WSAWG) initiatives including, but not restricted to:
	- other W3C WGs, esp the WS Activity WGs
	- OASIS TCs such as ebXML MS, RegRep, CPP/A, Provision, WSRP,
	SAML and others
	- Grid Forum
	- DAML-Services
	- OMG
	- WS-I.org

DAG0012.8 should include dynamic service discovery use case

DAG0012.9 must include service composition use case(s)

DAG0012.10 must include versioning use case(s)

I'm sure there's more:)

Okay, flame away!

Cheers,

Chris
