Metadata Export will export Bibliographic, Holdings, and Item data from SRS (source record storage) and Inventory Instance, Holdings, and Item records. If there is underlying source data (e.g., a MARC record), that will be exported. If there is no underlying source data, a simplified MARC record will be generated on the fly (not yet developed).
Data Export currently works with a list of instance IDs, which can be saved from a query in Inventory.
The UUIDs are saved in a .csv file which can be accessed under "Jobs" in Data export.
This generates a .mrc file that can be saved or opened directly from FOLIO.
