[OPEN-ILS-GENERAL] using Evergreen and Summon

[Duimovich, George]

Hello Gordana,
 
There are 'hooks' to do this - so you can adjust your method of dumping MARC for Summons to *exclude* records where deleted = 'true'  - this flag is set in the biblio.record_entry table.  
 
How is Summons consuming your MARC records? I assume that Summons is using the more common approach of indexing time based dumps (daily, weekly, etc.) from the database, correct? Or are they crawling the catalogue using unapi?
 
If if they're just indexing regular dumps, then you can set up (or customize) your script to generate a file with record id's from the database that excludes those bib id's where deleted = 'true'. This this file in turn can can be passed to the "marc_export" script for generating the dump that Summons will index.  You can also extend this approach to pass Summons records that have recently been deleted and / or modified if you want to avoid Summons having to re-index the entire database every night.
 
So it looks as if you'll have to do a minor adjustment to your process for extracting MARC records to use those flags (plus any others you'd like to add) to ensure Summons is just indexing what you want it to index.  
 
Hope that helps.

Happy New Year!
 
Niagara College has been using Evergreen and Summon quite successfully since September 2010. However, we've experienced a bit of a problem with deleted records. I've been in touch with Andrew Nagy of Serials Solutions and he provided the following info:
 
"The reason why your deleted records are getting indexed is that the MARC mapping that we have defined for your collection does not delinitate between a good record and a deleted record.  We need some way of knowing whether a record is real or deleted.  Do you know if evergreen can do this?"
 
Can anyone tell me if Evergreen can do this?
 
Thanks!
Gordana
