The '''Metadata Object Description Schema''' (MODS) is an [[Extensible Markup Language|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 standards|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<ref>{{cite web|url=http://presentations.ala.org/images/1/1f/Riley.pdf |title= MODS and MADS: Current implementations and future directions |accessdate=2011-08-01}}</ref>.

Line 19 ⟶ 14:

=== Relationship to MARC ===

The MODS record has been designed to carry key data elements from the [[MARC standards|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

==MARC Mapping to MODS ==

Line 801 ⟶ 794:

* 880$6=040,005,001,003 (with subfields as above) Repeat <recordInformation>, transform field as above with altRepGrp=""[1 digit character incrementing each pair]; Add also matching altRepGrp to equivalent element

== Advantages ==

The use of MODS provides several advantages compared to other metadata schemas<ref>{{cite web|url=http://presentations.ala.org/images/e/e3/Mccallum_guenther.pdf |title= Using MODS for discovery of LC’s rich collections |accessdate=2011-08-02}}</ref>:
