The MODS (Metadata Object Description Schema) was developed in 2002 by the Library of Congress as an XML schema for describing various types of library resources. It includes elements for core bibliographic information such as title, name, subject, and classification. As of 2009, the schema was in its third version. The standard is maintained by the MODS Editorial Committee of the Library of Congress. MODS has been implemented by several universities and digital libraries for describing digital collections.
