[ogsa-wg] Definition of "data service"

We invite comments on the definition of "data service" for the OGSA Data
Architecture (and hence the OGSA Glossary).
Currently we're looking at something like the following:
A service that exposes the capabilities or data of one or more
data resources within a service-oriented architecture.
A service that exposes the capabilities of one or more data
resources within a service-oriented architecture. These capabilities
might include data access, data transfer or data management.
We think either of these would be a significant improvement on our
previous definition. The emphasis in these new proposals is on linking
data resources into an SOA, which fits nicely with the OGSA definition
of a service:
A software component participating in a service-oriented
architecture that provides functionality and/or participates in
realizing one or more capabilities.
Our previous definition mentioned specific types of interfaces, which we
think is too specific and not resistant to change:
A service that is primarily intended to provide access to data
stored in one or more data resources. A data service will provide one or
more of the data access, data source or data sink interfaces defined in
the OGSA Data Architecture.
Comments welcome, especially before Monday's OGSA-WG call.
