XML-based bibliographic description schema developed by the United States Library of Congress' Network Development and Standards Office. MODS was designed as a compromise between the complexity of the MARC format used by libraries and the extreme simplicity of Dublin Core metadata.

About MODS

History and development

MODS was first announced for trial use in June, 2002. As of June 2010 it is at version 3.4[1].

The number of users of MODS is unknown. Implementers are encouraged to register their uses of MODS in the implementation registry on the official MODS website. To date there are about 35 projects listed in the registry, although it is assumed that many others are making use of the standard. Users are primarily operating in the area of digital libraries, and some of the registered uses are in digital library projects at the Library of Congress.

Relationship to MARC

The MODS record has been designed to carry key data elements from the MARC record but does not define all of the MARC fields and does not use the field and subfield tagging from the MARC standard. There are data elements in MODS that are not compatible with the MARC record so there is some loss translating from MARC to MODS and from MODS to MARC. There is no commitment on the part of the Library of Congress to maintain compatibility between the two metadata formats beyond what is convenient to the community of MODS users.

Advantages

The use of MODS provides several advantages compared to other metadata schemas[2]:

  • High compatibility with existing resource descriptions
  • Less detail than MARC so various internal record element sets can be mapped to MODS
  • Item descriptions from outside in DC and other simpler formats can be mapped and enhanced

Maintenance board

Revisions to the schema are suggested and discussed on the MODS listserv, and approved by the MODS Editorial Committee. The MODS/MADS Editorial Committee is an international group of volunteers responsible for maintaining editorial control over MODS and MADS and their accompanying documentation as well as for the MODS and MADS XML schemas[3]. The Library of Congress carries out the application of approved changes to the schema and maintains the official web site for the standard. There is no formal standards body involved in the MODS schema at this time.
