The Library of Congress' Network Development and MARC Standards Office, with interested experts, has developed the Metadata Authority Description Schema (MADS), an XML schema for an authority element set that may be used to provide metadata about agents (people, organizations), events, and terms (topics, geographics, genres, etc.). MADS was created to serve as a companion to the Metadata Object Description Schema (MODS). As such, MADS has a relationship to the MARC 21 Authority format, as MODS has to MARC 21 Bibliographic -- both carry selected data from MARC 21. MADS is expressed using the XML schema language of the World Wide Web Consortium. The standard will be developed and maintained by the Network Development and MARC Standards Office of the Library of Congress with input from users. |
