MARC Export Script for FOLIO

This code is a work in progress. It does produces a .json file that successfully imports into VuFind.

Feedback/modifications are welcome!

export-new.py - uses database queries to:

• In batches of 300K
• Gets a list of IDs for instances that are not blocked from discovery and state of the MARC record is 'ACTUAL'
• Using those IDs it retreives the MARC records
• Attempts to lookup holdings and items for the instance and adds 998 and 097 fields to the record
• Writes the records to a file (the python version writes MARC JSON)
• Attempts to filter out problem records (and logs them)

Notes: For the daily VuFind incremental update we were using the FOLIO OAI/PMH (marc21) module and the scripts built into VuFind.
