Venkata, I agree with your comments. David's diagrams are a good view of a
single runtime. We can use that view to describe what is happening in Java
and C++ code bases. I'm not convinced that tweakes to this diagram format
are easily going to be able to convey SCA motivation and values. SCA seems
to do two things implicitly.

1) describe the composition of finer grained components into coarser grained
components/services
2) describe an IT system in terms of the components/services from which it
is built.

SCA may do both of these things well but I don't think we are very good at
describing this. Some people come to us wanting to know how to build
services. Some people want to know how to build systems from services. So
the diagram we need is more like one of the context diagrams from the spec
that shows a system being built out of components and other non-SCA services
and, in turn, some of those components being composed from lower level
components.  The real value is then that you can do all of this with the
flexibility provided by the various containers and bindings, and in the
future policies etc.

Regards

Simon

David, this looks a really very nice arial view :-)

I agree that the DAS, SDO and Tools blocks should not overlay the core and
hosting platform blocks.

Now, if you look the diagram, it gives an impression of one huge
middleware
that encapsulates all sorts of containers.  The aspect of being able to
'integrate' distributed systems is not so evident.  We need to probably
think about positioning the 'extensions' differently to bring this point
out.  The intention is, when a person sees the picture he must get an idea
of where he is going to be able to use this.  Makes sense?

Thanks.
