Description Galen Charlton 2024-04-01 20:03:34 UTC 
The Z39.50 responder currently has a hard-coded expectation that the element set / composition provided by the client is either blank or "F".

It would be handy if it also supported "B" (brief) for backwards compatibility, since the default Zebra configuration also supports "B" (as effective a synonym for "F" (full)). 

Doing this would avoid a compatibility issue when switching from zebrasrv as the Z39.50 server to the Z39.50 responder for clients that happen to set the element set to "B".  In particular, we've seen at least one case where the EBSCO/EDS item availability checker was configured to request "B".

The error message associated with this is

returning error 239: Unsupported syntax/composition 1.2.840.10003.5.10/B Koha::Z3950Responder::Session::log_error /usr/share/koha/lib/Koha/Z3950Responder/Session.pm (341)
