As an ILS vendor that is providing Z39.50 services to our customers, we have
heard - and responded to - the need for Z39.50 Updating.  We now offer it to
our customers who want it; they can update databases under our control, as
well as other databases that permit it (e.g., OCLC).

For us to move to ZNG - whenever that may be and whatever that might entail
-  we would have to offer at least as many services to our customers as
Z39.50 does.  Which means that the ability to Update through ZNG is
essential.  What we call it is less important than ensuring its
availability.

I think we need to distinguish here between ZING and SRW.

There was a fairly long debate but the upshot is that we aren't adding
Update to SRW. There are some nomenclature issues to be ironed out, but I
hope we don't call it SRW Update (or Update for SRW) etc.

What we are edging towards is having a family of WebService (lets call that
ZING, but again nomenclature hasn't been resolved), which include SRW and
Update (and possibly others). Each of these could stand alone, but could
also be used together (and combined may eventually provide the same
functionality of Z39.50 over WebService).

There is a question of whether an Update service is really needed (given
that there are other approaches) - I've drafted an initial summary of other
approaches and how they could relate to the Update service discussions at
http://www.ceridwen.com/srw/record-update/crud.html
