The glossary in the OGSA Data Architecture document currently defines "data set" as: "An encoding of data in a syntax suitable for externalisation outside of a data service, for example communication to/from a data service. Examples include a WebRowSet encoding of an SQL query result set, a JPEG encoded byte array, and a ZIP encoded byte array of a set of files." Is this correct? I'm not convinced that we use the term consistently to mean this - sometimes we just seem to mean a defined set of data items on a resource. We may need to check each occurrence of the term (there aren't too many).

Hi,
The glossary in the OGSA Data Architecture document currently defines "data set" as:
"An encoding of data in a syntax suitable for externalisation outside of a data service, for example communication to/from a data service.
Examples include a WebRowSet encoding of an SQL query result set, a JPEG encoded byte array, and a ZIP encoded byte array of a set of files."
Is this correct?
I think this definition may have come from DAIS. Have to be slightly careful as the term is used in various other places (hence the term is slightly over-loaded), for instance: http://www.devarticles.com/c/a/ADO.NET/Datasets-in-Microsoft.Net/ and this is only one other reference to it ...

Dave,
The definition looks reasonable as it pertains to the data "exported" from
a data service.
But it seems that we use the term to refer to the data contained within a
data service (i.e., unarchiected data if you will). Could we replace
these usages with a different phrase, perhaps something like "the data
resource's data"? or "the data held by the data resource"? A bit awkward
in phrasing but it avoids the need to have a two headed definition or
trying to invent a new term.
