Jim,
Thanks for the comments. I took a look at the links and your comments. How
about this write-up?


Welcome to the Apache Tuscany free open source project that is licensed
under version 2 of the Apache
License<http://www.apache.org/licenses/LICENSE-2.0_>.
This project is currently in incubation within the Apache incubator.

The aim of the Apache Tuscany is to create, as a community, a robust
framework that simplifies the development of SOA-based systems through
seamless handling of many infrastructure and data handling complexities
which exist in heterogeneous Service Oriented Architecture (SOA)
environment.
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.

Tuscany reduces development effort and cost by enabling the
application developer to focus on addressing the business problem.
Tuscanyconsists of the following technologies:


· Tuscany runtime is based on Service Component Architecture (SCA) specification and provides the infrastructure for hosting and assembling services. This runtime can easily be extended to support new communication
transports, qualities of service and programming models.
I'd make sure we mention C++ and Java, keeping thins simple as in:

- SCA-based Java and C++ runtimes for hosting and assembling services
which can be extended to support new communications transports,
qualities of service, and programming models


Tuscany runtime
The Tuscany SCA runtime
can be used independently or in conjunction with other technologies such as Spring, Axis, and Celtix to create and assemble composite applications.

· Tuscany offers an implementation for Service Data Object (SDO)
specification which enables the application developer with a uniform
interface for handling and tracking disparate data as it flows across
service assemblies.
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

·         Tuscany also provides a data access service (DAS) as an
intermediary between SDO and different types of persistent data.

The specifications that Tuscany is based on are located at
www.osoa.org .   Please
join us to build this first class infrastructure that simplifies development
of SOA-based systems.
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.

A high level view of the Tuscany offerings is shown below. You can click on the diagram to learn more about specific technologies. Tuscany is supported
in Java and C++.

I think this is an improvement over what we have but have a couple of
additional suggestions. Specifically, I don't think the statement
"with little or no programming" is something we want to claim. It is
not really accurate and the primary audience coming to the website I
imagine to be developers who by nature don't believe those kind of
statements. I would prefer the page to be oriented to developers,
with the particular purpose of recruiting those interested in writing
systems-level software, i.e. working on Tuscany. I find these types
to be generally skeptical by nature and focused on "cool technologies."

Some good examples to use for comparison would be Microsoft (who I
think has generally excellent developer marketing), Spring (Rod is
also a really good marketer too) and ServiceMix:

http://msdn.microsoft.com/winfx/technologies/communication/ default.aspx

http://www.springframework.org/

http://www.servicemix.org/site/home.html


Based on these, I would rephrase and highlight the message that
developers can leverage Tuscany technologies to build out SOA-based
systems (as opposed to "business solutions"):

The aim of the Apache Tuscany is to create infrastructure that
simplifies the development of SOA-based systems. Tuscany technologies
may be used independently or in conjunction with other technologies
such as Spring, Axis, and Celtix to create and assemble composite
applications, or "service assemblies". Specifically, Tuscany provides:

- SCA-based Java and C++ runtimes for hosting and assembling services
which can be extended to support new communications transports,
qualities of service, and programming models
- An SDO implementation for representing and tracking data as it
flows across service assemblies
- A Data Access Service for declaratively accessing persistent data
in a service-oriented manner
