RE: Next meeting

Dear all,

In relation to Z39.50/XER/SOAP/WSDL etc. I've been working on a service
description for Z39.50 using WSDL (using an xsd derived from the ASN.1 by
Eliot Christian using XER). A draft of this is at
http://www.lib.ox.ac.uk/jafer/ez3950/z3950-wsdl.html (at this stage all
namespace URI's are provisional/temporary)

In essence (although there is stil some outstanding work in the fine
details) the WSDL describes all the Z39.50 services (Port Types in WSDL
terminology) in Z39.50 version 3.0.

The beauty of WSDL is that having given the service description (Port Types)
you can then give (possibly multiple) bindings. A binding in WSDL terms
describes how the messages are encoded and passed over the wire. It should
be possible to give a WSDL binding for BER over TCP/IP (i.e. the WSDL
description should be able to cover the status quo). I have included a
binding for Z39.50 over XER/SOAP (plus a slightly fuller explanation of the
details at http://www.lib.ox.ac.uk/jafer/ez3950/ez3950.html )

Since when constructing a binding you can specify which services are bound
to the encoding/transport layer, and even which parts of messages get bound,
it is possible to specify a profile as a WSDL binding (e.g. this profile
supports Init, Search, Present, Close, but within Search does not support
the piggy back components of the searchRequest and searchResponse could be
specified in a WSDL binding). This may be relevant to Bath. However other
aspects of Bath such as use attribute support and server behaviour on
performing searches may be beyond the scope of WSDL.

Would the Bath meeting be one or two days?  It looks like an ambitious
agenda
(though I realize these are tentative topics). some of these might be agenda
items for the ZIG at large. Could we consider aligning the two agendas?
People
going to both the Bath and ZIG meetings could end-up spending five days,
potentially with considerable overlap. Let's try to avoid this if possible.
