Thank you for your comments Allen.
In that case I vote for Dave Berry's definition:
"A service that provides interfaces to the capabilities and data of one or more data resources within a service-oriented architecture."
There is a separate question as to whether the data *is* a capability; I suspect it is, at least in some abstract sense. On the other hand, you might wish to distinguish the data as a special kind of capability that needs non-generic handling.
and the Data Resource is .....
A data resource is an abstraction of a file, so I'd imagine that you'd want to describe it as a resource that is an ordered collection of organized information. (The idea is that it doesn't have to be in a file, but it does have many file-like characteristics.) It's strongly beneficial to the overall OGSA if you can have data resources being a subclass of resources (by referencing the OGSA glossary). Donal.
