Re: [soa-blueprints] Primer

Can be begin a thread with the subject "Definition of an SOA Blueprint". I think the similar one for SOA-RM on "definition of service" proved very useful in surfacing a host of ideas that eventually found their way into the successive drafts. The Petstore sounds like the perfect example to bounce off the definition to test its scope and the anti-patterns should clearly be shown to be wanting because they somehow fail the definition.

For the Generico case, the name "blueprints" was derived from the J2EE
"Petstore" blueprints. The Middleware Company had worked extensively
with the petstore, frequently performing productivity studies for
vendors. I guess you can say the usage of blueprint in the petstore
case was to provide a sample application that best illustrated the use
of J2EE (i.e. exercising all the features). I would suspect we want to
define it with more scope for this TC.

I have not been following the email carefully enough, so forgive me if this
has already been established but

1. Exactly what is a blueprint?
2. What purpose does it serve?
3. Why should I think one will be generally applicable?
4. Why do I care?

Do we expect that a blueprint will be a sort of turnkey formula? How do we
determine the limits of applicability for a given blueprint? Are there
underlying assumptions that all blueprints have in common, or is each
blueprint fundamentally different (a very possible construction), or are
there fundamental groupings with multiple non-redundant examples in each
group?

I think agreeing on a clear strawman definition of blueprint is essential.
It can be modified as we learn more but we need a clear starting point.

One question to pose to the group is maybe the case study actually becomes a
type of primer for the blueprints once the blueprints are defined.

Thoughts?
