IMO the first statement needs to be really direct and as free of
buzzwords as possible since it is the first thing people are
going to
judge us on. I'd try and limit the use of SOA as much as possible
since the term is abused these days. I'd also try and not talk about
"business problems" since we are targeting primarily systems
developers (to join the project) and secondarily end-user
applications developers. With that in mind, I would say Tuscany is
"infrastructure" (as opposed to a "framework" like Rails, RIFE,
parts
of Spring, etc.) that simplifies the development of SOA-based
systems. It does so by providing technology for composing service
networks ("service assemblies") based on SCA and technologies for
managing data in that environment based on SDO.
At some point I also think we need to make it clear that SCA, SDO
and
DAS are independent technologies.
If I had to characterize the message I would want to send the two
constituencies it would be:
- system developers: the stuff we're working on involves solving
really hard problems and you should be part of building out the next
generation infrastructure and doing innovative things.
- application developers: our technologies are cool, work with stuff
you already know, and will enable you to build really interesting
applications.

I'd make sure we mention C++ and Java, keeping thins simple as in:

services

I'd maybe reword slightly as:
An SDO implementation which provides a uniform interface for
handling
and tracking disparate data as it flows across service assemblies

I'd maybe not highlight the specifications as much. I think it is
important that we convey the message Tuscany is not limited to SCA
and SDO and we're not just following what a group of vendors write
up. It may also be good to say that Tuscany is a way to feed back
into those specifications.
