I would suggest the following for SRU :

1. Records should have persistent URIs.

2. Updates should be performed by using an http PUT method to the persistent
URIs.

3. Security should be covered by the facilities in http.

4. If it is necessary to deal with multiple updates look at the manner in
which W3C has handled this in the Amaya web browser.

This is a note sent to me, which would be posted
to this list except the list is private, for
implementors only. So two questions:

1. any opinions on how our "new generation" Z39.50
might treat update, if at all?
2. how should we treat questions like this, open
up the list? start a new, public list, for
discussion?

To whom it may concern,

I have a question: In SRU there is currently no
operation comparable to the
"Database Update Extended Service Facility" of
Z39.50 (EXT1.5 in the Z39.50
Document). Will an related operation be introduced
in the future?
With kind regards

Jürgen Kett
