The diagram is the same, but you should be looking at the document that includes it (IVOarch2.htm), not just the diagram in isolation.

These are the different kinds of message that go back and forth between services. The exact nature of these messages includes VOTable and FITS and simple requests, but also includes the richer messages that contain serialized data models, for example VOResource.

That section of the diaram is addressed in the last section, Data Engineering, that Reagan has written.

I must admit that I am not sure how the semantic web queries fit in to the diagram. Suggestions? Please also read the UCD section of the document.

We could put it in -- or we could think of it as a throwaway toy -- what do people think?

Query requests and response that are a bit richer. Maybe I should just make them regular arrows.

Because we have a strong connection to it.We should use their literature ID system as part of the links from our registry. You think we should dump that box?

Because registries talk to other egistries. The global registry (Distributed Virtual Registry) talks to itself with OAI.

This would be a rewrite of the Grid/Web services section, and/or the Applications section. Should we have an Applications section in an Architecture document?
