The MODS/MADS Editorial Committee and the Library of Congress are pleased to announce that a new incremental version of the MODS Schema, 3.6, is now available at:

Some changes of particular note in MODS 3.6 are:

  1. New attributes added to the <hierarchicalGeographic> subelement of <subject>.  Further information and examples can be found at:  http://www.loc.gov/standards/mods/changes-3-6-hierarchicalGeographic.html
  2. Four new attributes (that refer to other attributes) added to <relatedItem>
  3. Addition of under
  4. The subelement of has been made extensible
  5. Addition of subelement of with type attributes

A complete list of changes can be found at: http://www.loc.gov/standards/mods/changes-3-6.html. Revised versions of the MODS User Guidelines, the MARC to MODS mapping, and the XSLT conversion that incorporate the 3.6 changes will be available on the MODS web site soon.
