Per our meeting (1/22/2019) on Implications of migrating MARC Bibs from Inventory to SRS:
Linking from Instance records will need in near future to support linking to multiple source records, e.g. MARC, DC, BIBFRAME.
The mod-inventory-storage need to be enhanced so it supports
- link should be an array of objects to allow for 1-to-many relation and
- introducing the "type" and "primary=yes|no"
