Proposed New Version of METS Schema Released (June 17, 2003)
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 //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:
- 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."
- "MODS" has been added to the available controlled vocabulary
- 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,
- 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 [email protected] or, sent
privately to Jerome McDonough, the METS Editorial Board Chair,
at [email protected].
