Validation rules
- MARC BIB : Tenant cannot change the validation rules for Leader (LDR), 001, 005, 245, 999 ff, and control fields 006/007/008
- MARC AUTHORITY: Tenant cannot change the validation rules for Leader (LDR), 001, 005, 1XX, 999 ff, and control field 008.
- MARC Field
- Required means the field is required to save the record.
- Non-repeatable (NR)/Repeatable (R) = Cannot save a record if the MARC field is set to NR and the MARC tag has been entered multiple times
- Indicator 1
- If user enters an invalid value then system will log it as a Warn but proceed with saving the record
- Indicator 2
- If user enters an invalid value then system will log it as a Warn but proceed with saving the record
- Subfield
- If user enters an invalid value then system will log it as a Warn but proceed with saving the record
- Non-repeatable (NR)/Repeatable (R) = Cannot save a record if the subfield is set to NR and the subfield has been entered multiple times
- If subfield is required then cannot save the record
- If the library enters a MARC field that is not on the validation list then system will log it as a Warn but proceed with saving the record
- ECS
- Local record will validate against the member library's validation list
- Shared record will validate against the central tenant's validation list
Validation Rules Logic Overview
WARN: Warn message, but allow user to bypass and save
PREVENT SAVE : Present error toast and do not allow user to save
Required/ Optional | Field Repeatable (R) / Not Repeatable (NR) | Ind 1 code | Ind 2 code | Subfield code | Subfield code required / optional | Subfield code Repeatable (R) / Not Repeatable (NR) |
|---|---|---|---|---|---|---|
PREVENT SAVE (if Required) | PREVENT SAVE (if NR and user enters duplicate) | WARN (if invalid value) | WARN (if invalid value) | WARN (if invalid value) | PREVENT SAVE (if Required) | PREVENT SAVE (if NR and user enters duplicate) |
Types of MARC fields
System-level: Tenant cannot change validation rules for the following fields
MARC BIB : LDR, 001, 005, 245, 999 ff, and control fields 006/007/008.
MARC AUTHORITY: LDR, 001, 005, 1XX, 999 ff, and control field 008.
Non-local: Some validation rules can be configured at the tenant level. Non-local fields are documented by LOC as not local. (ex. 130)
Local: all validation rules can be configured by the tenant. Local fields are:
Not documented by LOC as a valid tag (ex. 192)
- Documented as a MARC local tag by LOC > 9xx, x9x, or xx9 (except 999 and 490)

- Tenant cannot change subfield code and subfield code names specified by MARC
- But Tenant can add/append more valid subfield codes and subfield code names NOT specified by MARC (if invalid value) (IOW tenant can define local subfield codes and subfield code names)
- Non-repeatable (NR) / Repeatable (R) - (Tenant can set/modify for local subfield codes but not MARC specified exceptions $9 and possibly $0)
- Subfield is required/optional (Tenant can set required/optional for any subfield code exceptions $9 and possibly $0)
- Exceptions might be $9 and $0 for a field that can be controlled by an authority heading
