[Missing Practical Stuff]

[Tony Linde]

There's a lot more work to be done in this area. The Format item is
insufficient to describe  the input or output of a service - it might
suffice to describe the generic form of output of a data collection (except
that a data collection cannot output anything, only a data service can do
that) but it doesn't cater for versions (ie, if VOTable is produced, then
which version).

The registry sessions touched on this when Paul described the AstroGrid
application extensions to the schema and we'll need to do a lot more in this
respect up to and during the next interop meeting.

Cheers,
Tony.
