[ogsa-d-wg] The big picture

Dear All, I've been asked to provide a diagram that shows the "big picture" of the OGSA Data Architecture. This would be used in the OGSA 1.5 document and in the overview section of our document(s), and perhaps also in powerpoint presentations. I've come up with the pair of diagrams and associated text in the attachment. Please take a look.
