MARC 21 Authority Format Mapping to MADS
Schema version 2.0

Revised June 2011

This mapping is for use with MADS Schema version 2.0 . The previous version of this mapping for use with the MADS Schema version 1.0 is located online at: www.loc.gov/standards/mads/mads-mapping-1-0.html.

Introduction

Mapping

1. Introduction

This mapping gives equivalencies between the MARC 21 Authority Format and MADS, but is not intended to be a crosswalk that allows for bi-directional conversions without some loss of data. Where there is no equivalent MARC 21 element, this mapping says "no MARC 21 equivalent".

Setting authority attribute

The authority attribute is available for all descriptors (i.e. subelements) under <authority>, <variant>, and <related>. In converting MARC 21 records to MADS, this mapping provides for setting values under <authority> and <related> only when type="equivalent". This is because MARC 21 authority records do not generally mix headings from different thesauri/authority files in the 5XX reference fields, but only when linking to an equivalent form in another thesaurus/authority file in the 7XX fields (Established Heading Linking Entry). If other practices/policies are used in systems wishing to convert records from MARC 21 authorities to MADS, the authority attribute may be included in <related> and <variant> as appropriate, but it is not reflected in this mapping.

When there is more than one descriptor under <authority> the authority attribute should be used only with the first (primary) entry element to eliminate needless redundancy. In the above mappings, the primary entry element is indicated first and if there are additional descriptors the instruction is to "Add <tag>".

Addition of authority attribute Use mapping above and add authority attribute as follows:
