This is a summary chart of the default MARC Bib-to-Inventory Instance mappings supplied with FOLIO. It is current as of Orchid.

The most recent JSON rules can be found here: MARC Bibliographic Default JSON Rules

The definitive decisions and documentation for the mappings can be found in the FOLIJET Instance from MARC and FOLIJET MARC 880 fields tabs of this spreadsheet. This spreadsheet references the relevant Jiras when mappings have been changed after the initial mappings and also shows mappings that have not yet been implemented.

If libraries opt to customize the default mappings, please see Notes on Customizing Default MARC-Inventory Maps and Release Updates

Instance field	Type (when applicable)	MARC mapping	Notes
Instance UUID		999 ff $i
Suppress from discovery		[not mapped]
Staff suppress		[not mapped]
Previously held		[not mapped]
HRID		001	If the FOLIO HRID is not in the 001 field of an imported MARC Bib record, the existing 001 is moved to an 035 field, preceded by any 003 data in parentheses, e.g. 001 1234567 and 003 OCoLC would become 035 (OCoLC)1234567. Once that is done, the Instance HRID is placed in the 001 field.

MARC 880 (Alternate Graphical Representation) fields

Until FOLIO can support multiple graphical representations of the same main entry fields (primary contributor, title), MARC 880 fields that correspond to 1xx fields will be mapped as if they are 7xx fields.

MARC 880 field	Map to Instance field
Obtain the actual MARC field from the first 3 digits in $6
For all fields except 100, 110, 111, 245: Map the data from the subfields following the $6 to the same Instance fields as the actual MARC fields
For field 100, map the data from the subfields following the $6 to the same Instance field as the 700 MARC field	Contributor-Personal name
For field 110, map the data from the subfields following the $6 to the same Instance field as the 710 MARC field	Contributor-Corporate name
For field 111, map the data from the subfields following the $6 to the same Instance field as the 711 MARC field	Contributor-Meeting name
For field 245, map the data from the subfields following the $6 to the same Instance field as the 246 MARC field	Alternative title
