In the first figure there seems to be
a slight inconsistency in terminology. The key says that blue ovals
are services. But the two middle blue boxes are labeled as being
resources. Now as I understand how things are modeled, a resource
is not a service so this is confusing. Based on what this is trying
to say, I fear that you are going to need to expand these two ovals and
label them as services. But, at the same time, add a data resource
box inside of each so that the data transfer arrow is connected in a way
that is consistent with the text.
I also realize that I must be confused
about data transfer. I thought that we were pushing the view that
transfer occurs between data services in a logical sense. But that
the optimized implementation of data transfer would inevitably connect
directly to the resources inside of a data service.

[ogsa-d-wg] The big picture,
version 2
All,
Here is a revised version of the "big picture" architecture diagrams.
I've taken account of the feedback I received by e-mail and at last
week's meeting.
Please take a look and send comments.
Dave.
