Koha Z39.50 client process isn't easy to understand from a end-user perspective. Current process: ◊ In cataloguing, a search to multiple z3950 target is sent. ◊ Result is displayed. 20 first results are displayed for each target. ◊ Each record is stored in import_* tables for further usage via 'reservoir'. ◊ By clicking on Import, one record is copied in data entry page. ◊ Cataloger can modify biblio record, localized it, etc. ◊ In next cataloguing operation, a search will be done both in catalog and reservoir (import_biblios table), and will retrieve eventually biblio records from previous z3950 searches. Some design choices are disputable: ◊ Why just 20 records per host are displayed? ◊ Why all retrieved records are stored in reservoir? People generally don't understand that. Why 20 and not 5 or 100 records? When a search is done by author, it is to catalog a specific book from this author. But with the current design, the library will fill its reservoir with biblio records describing books which will generally never enter into its catalog. ◊ Search in reservoir is done with BreedingSearch function only on 'title' and 'isbn' fields. So it's impossible to retrieve a biblio record by author. ◊ There is no user interface allowing to see what's going on with biblio records stored in reservoir and coming from z3950 searches. There is such an interface for staged records: those imported explicitly into reservoir from files (in Tools). ◊ So if a library uses to do search in 4 z3950 hosts, each search may add 4 x 20 = 60 records in import_biblios and import_records tables. The number of records added this way will grow indefinitely without any mean to clean reservoir. Some ideas of improvement: ◊ Add a syspref 'ReservoirZ3950' which when at false disable biblio records adding from z3950 searches. ◊ Add an UI in Tools to see the number of biblio records in reservoir added from z3950 searches. ◊ Add a 'clear' option in Tool to delete all records in reservoir coming from z3950, and eventually also coming from file imports.
