Move holdings and/or items - when the change is triggered by external source

Goal: Transfer holdings from one instance to another when the change is triggered outside of FOLIO. This use case can be relevant with non-SRS implementation, e.g. like Chalmers and GBV.

Task:

1. gather use cases for:
   • Which external sources can trigger a change of holdings and/or item
   • When are changes of holdings and/or items being trigged by an external source
   • How do FOLIO/Inventory receive input on changes triggered by an external source
   • How do FOLIO\/Inventory implement the changes (which automatic processes and/or manual processes? Which apps are involved in this chain: Data Import, Orders etc.

Uses case development for OCLC CBS union catalogues (e.g. GBV, hebis, SWB)

1. In an external system, a holdings and/or item record is moved from one bib record to another.

• The process has to be mirrored in Inventory, so that the new relationships are established (Item -> Holdings -> Instance).

mod-inventory-update module (NEW FOLIO module)

• Definition of Update: update & insert (includes deletion and move)
• FOLIO/Inventory would receive input on changes triggered by an external source via this new module
• There are no changes to Folio Inventory required and nothing has to be implemented. The new module could be considered part of Inventory.
