SV: InitResponse Options Bit 9

Mr. Warnock,

Have you taken 3.2.2.1.2 point 1 in Z39.50-1995 into consideration?

In many cases it may be highly contextually dependant which databases may be
searched at the same time. I think this is the correct approach:
1) You should just try to search the various databases by the same search
request.
2) If the server doesn't support that, it should send a non-surrogate
response record for the diagnostic with code 23 back to the client. This
diagnostic is defined on page 86 and has this meaning: "Specified
combination of databases not supported".
3) If the client receives such a diagnostic it must search each database
individually.

In this way you just use common features for your specific request.

What do you think of this kind of approach?


Best regards,

Henrik Dahl

Emne: InitResponse Options Bit 9



Hi all,

I'm wondering if any of you might be aware of anyone using Options bit 9
in the InitResponse?  It is currently (as far as I can tell) listed as
unused in all of the documentation.  The group working on updating
current CIP profile is interested in using it locally (ie, only for CIP
servers) to indicate support for multiple database names in the
SearchRequest.

Alternative suggestions gratefully considered, as well.

Thanks!
