===History and development===

The Library of Congress' Network Development and MARC Standards Office, with interested experts, developed the Metadata Object Description Schema (MODS) in 2002 for a bibliographic element set that may be used for a variety of purposes, and particularly for library applications. As an XML schema it is intended to be able to carry selected data from existing MARC 21 records as well as to enable the creation of original resource description records. It includes a subset of MARC fields and uses language-based tags rather than numeric ones, in some cases regrouping elements from the MARC 21 bibliographic format. MODS was first announced for trial use in June 2002. As of May 5, 2015 it is at version 3.6.<ref>{{cite web |url=httphttps://www.loc.gov/standards/mods/mods-3-6-announcement.html |title= MODS 3.6 released |accessdate=2016-06-20}}</ref>

The number of users of MODS is unknown. Implementers are encouraged to register their uses of MODS in the [httphttps://www.loc.gov/standards/mods/registry.php 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 library|digital libraries]], and some of the registered uses are in digital library projects at the [[Library of Congress]].

Revisions to the schema are suggested and discussed on the [http://listserv.loc.gov/listarch/mods.html 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.<ref>{{cite web |url=httphttps://www.loc.gov/standards/mods/editorial-committee.html |title= MODS/MADS Editorial Committee |accessdate=2011-08-02}}</ref> 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.
