RE: [soa-blueprints] Suggestion

[<marchadr@wellsfargo.com>]

One thing I would also like to get out of this is what seems to be the goal in the Executive Summary that was sent out for the group.

"The SOA Blueprint validates the SOA specification and blueprint through a real-world reference implementation and
provides a concrete implementation of the SOA model through various vendors' technologies. Thus, SOA
Blueprints give enterprises real-world implementations that can be used as a departure point for their own
implementations, which can also benefit from the body of SOA best practices that the blueprints provide."

Essentially if you look at the W3C and Oasis committee groups there are a variety of standards that are being defined around services. I would like to see in what situations do people think specific standards/implementations should be used.

For instance, 
  - When would I use SAML within a service context, if at all?
  - When would I use Web Services Notifications?
  - How would I incorporate Web Services Composite Application Frameworks?
  - When would BPEL be appropriately used? Would it be integrated within a service bus to managed orchestration of services?
  - Would I use Asynchronous Service Access Protocol standard?
  - Can the Web Services Distributed Management standard be the basis of a service bus?

These are just some questions to kind of get a feel for what I was thinking of as far as what the blueprints could provide.

Robert,

To clarify what I meant by deliverables:
- A product of this group and not a product of an actual service implementation 
  (service implementation - instance of a blueprint pattern I would imagine)

To see if I understood your points here is a list based on your comments:

1. Define a best practice approach of turning business process/use cases, etc. into real project based deliverables that align with the SOA blueprints
2. Establish a set of business use cases to drive the definitions of SOA blueprints
3. Best practices on how to identify a blueprint to use for a given real world application (assuming we flush out the blueprints)
4. Patterns to follow in implementing an SOA

The question is which ones to address within this group.

" I couldn't quite get a handle on whether our group
is focused more on what is delivered vs. defining some best practices on
how to create the deliverables."

This is a good question and one that I imagine we need to answer before proceeding to far along.
I would imagine we are defining best practices on how to create specific domain deliverables as well as patterns to follow within SOA implementations.

Daniel,

Here is my take on trying to continue this thread.  As I was trying to
frame the problem - I couldn't quite get a handle on whether our group
is focused more on what is delivered vs. defining some best practices on
how to create the deliverables.

If we look at the process perspective, can we start at what are the
prerequisites for beginning to build the SOA blueprint? As an example,
it might be that a domain model and some business use cases are required
to start building the blueprints.  Part of our task could be showing how
to take these prerequisite artifacts and translate them into the set of
deliverables that comprise the SOA blueprints.

Miko - I am anxious to see the information that Steve contributed - you
did a great job of selling it last night :-)

Miko,

I would like to suggest that maybe we have people establish what they
want to see come out of the group.
If we can get people to send it through email we can help to establish
an end target goal of the blueprints.

Also with that in mind I will contribute my thoughts to this based on
some experience I have defining internal SOA blueprints.

I see the blueprints can be established in a few different ways.

First, an SOA blueprint can be how the services interact and are managed
within the context of your service oriented environment.
Second, an SOA blueprint can be an expression of how common business
process can be evolved into an SOA.
Third, an SOA blueprint is specific to a domain since the domain
establishes business processes and the SOA realizes those processes.

The first can be leverage by the other ones. The last one is a difficult
exercise to achieve and is very similar to having a unified business
language (see the oasis standard).
Maybe in some ways the SOA blueprints can leverage some of the work that
is done by the unified business language standard.

These are some ideas to trigger more definition on the end state of this
technical committee.
Thoughts?

Obviously the body of work that was done as part of the middleware group
seems to straddle the First and Second points.

Thanks,
