  A proposed new version of the METS XML schema (version 1.3) has been
drafted by the
METS Editorial Board and is now available at the METS web site at
http://www.loc.gov/standards/mets/version13/mets.v1-3.xsd. The Editorial Board
would like to invite the METS community to review the new version of the
METS schema
and send any comments they may to the Editorial Board. The new version of
METS makes
the following changes:

1. The opening comments describing the OBJID attribute on the root METS
element have
been changed to read as follows: "2. OBJID: a primary identifier assigned
to the METS object."

2. "MODS" has been added to the available controlled vocabulary in MDTYPEs.

3. The attributes on the element have been altered so that instead of a
single CHECKSUM
attribute, it now has both CHECKSUM and CHECKSUMTYPE, where CHECKSUMTYPE
is a controlled vocabulary as follows:

      HAVAL, MD5, SHA-1, SHA-256, SHA-384, SHA-512, TIGER, WHIRLPOOL

4. The BehaviorSec element definition has been altered to make it
recursive, and add a new
behavior element has been added to wrap mechanism and interfaceDef
elements. This allows
you to establish a hierarchical grouping of behaviors similar to that
available in the FileSec.

The METS Editorial Board is now calling for comments on this proposed
schema. Comments
may either be publicly posted to the METS mailing list at [log in to unmask] or,
sent privately to
Jerome McDonough, the METS Editorial Board Chair, at [log in to unmask]
