MARC FAST-TRACK PROPOSAL
DATE: May 4, 2023
REVISED:
NAME: Adding Subfields $0 and $1 to Field 658 of the MARC 21 Bibliographic Format
SOURCE: Den norske katalogkomité (The Norwegian Cataloguing Committee)
SUMMARY: This paper proposes adding subfields $0 (Authority record control number or standard number) and $1 (Real World Object URI) to field 658 (Index Term-Curriculum Objective) in the MARC 21 Bibliographic Format.
KEYWORDS: Field 658 (BD); Index Term-Curriculum Objective (BD); Subfield $0, in field 658 (BD); Authority record control number or standard number (BD); Subfield $1, in field 658 (BD); Real World Object URI (BD)
RELATED: 2023-DP02; 2017-8; 2019-03; 2020-FT02; 2020-FT03; 2021-04
STATUS/COMMENTS:
02/01/23 – Discussion Paper 2023-DP02 was converted to a MARC Fast-Track proposal at MAC Midwinter meeting.
05/05/23 – Submitted to the MARC Steering Group for consideration as a MARC Fast-Track proposal.
05/15/23 – Results of MARC Steering Group review - Approved.
06/21/23 – Changes made to the MARC documentation as part of MARC Update No. 36 (June 2023).
Much work has been done already to aid in capturing URIs in MARC authority and bibliographic records. Subfields $0 (Authority record control number or standard number) and $1 (Real World Object URI) have been added to numerous fields (see for example Marc Proposals No. 2017-08, 2019-03, 2020-FT02, 2020-FT03, 2021-04).
Unlike most other 6XX subject access fields, to which subfields $0 and $1 were added following the approval of MARC Proposal 2017-08, field 658 (Index Term - Curriculum Objective) does not yet support subfields $0 and $1, and it is therefore not possible to link curriculum objective subject entries to an RWO URI. In order to increase compatibility with linked data design principles, MARC records should be able to hold URIs where they are available.
The previous paper, 2023-DP02, was generally supported by the MARC Advisory Committee at the 2023 Midwinter meeting, and a motion was approved to convert the paper into a fast-track proposal.
The Norwegian Ministry of Education (UDIR) has established URIs for their national curriculum codes, and other educational bodies may soon follow suit. Adding subfield $1 to field 658 would allow MARC records to support the identifier and IRI recording methods for the subject element in the RDA Toolkit. This linkage would be of value especially in countries where more than one official language is used across catalogs, and it would also allow information valuable for selecting material such as subjects being superseded by other subjects or removed from the national curriculum.
We would also suggest that subfield $0 be defined, as other educational bodies may opt for non-URI identifiers for their standardized curriculums.
In field 658 (Index Term-Curriculum Objective) of the MARC 21 Bibliographic Format, define the following subfields:
$0 - Authority record control number or standard number (R)
See description of this subfield in Appendix A: Control Subfields.$1 - Real World Object URI (R)
See description of this subfield in Appendix A: Control Subfields.

658 ## $a Matematikk 10. årstrinn $c MAT0015 $1 http://psi.udir.no/kl06/MAT0015 $2 udir
Example 6
500 ## $a Subject removed from national curriculum as of 2021-12-31, no direct replacement course
658 ## $a Technical Services $c TIP1002 $1 http://psi.udir.no/kl06/TIP1002 $2 udir
Adding $0 and $1 to 658 could reduce the data loss in BIBFRAME to MARC conversion.
In field 658 (Index Term-Curriculum Objective) of the MARC 21 Bibliographic Format, define the following subfields:
$0 - Authority record control number or standard number (R)
$1 - Real World Object URI (R)
