Purpose: Establish linking between an Instance record in Inventory to a source record in the Generic bib storage.
The blob record in the Generic bib storage can be e.g.
a) imported into the system and stored in the Generic bib Storage and converted to FOLIO format and stored as a instance record in Inventory, or
b) coming as an external source record from e.g. a Knowledge Base (e.g. EBSCO KB), and stored in the Generic Bib Storage and converted to FOLIO Inventory format.
In the instance record the element Metadata source is implemented (in alpha). This element is auto-populated with source of the Generic bib storage record and its format, if applicable (e.g. "Local: MARC" or "EPKB")
Define the linking between the source record, which is the original (rich) native metadata format stored in the Generic Bib Storage and the instance record in Inventory.
