Arthur's statement regarding the importance of discovery in the Grid
applications we are looking at.
A single "type" of a service, as manifested by an explicit association
between a wsdl:interface and a wsdl:service would make searching within
registries (UDDI or otherwise) easier.

As it stands now, some of the service interfaces we have been building have
to return a list of interfaces supported.  Reducing this to a singleton, ie
THE interface implemented by the service, simplifies a couple of aspects of
the OGSI programming  model.

Some amendments to the minutes:

1. I wasn't the one who said this:

... IBM\Arthur notes that some aspects of Schema are not well understood
and thus not implemented.

It's probably true but I don't recall who said that.

2. I mentioned a third benefit to the proposal for a service to implement a
single interface:

Searching for a service that implements a given interface, e.g. in UDDI,
becomes simpler if the service has an interface explicitly associated with
it. I believe this is important for GRID.
