Proposed new versions of the METS schema (and associated XLink schema)
the METS Profile schema are now available at the METS website
(http://www.loc.gov/standards/mets). Here's a summary of the changes
1. Documentation for attributes has been relocated to make it easier to
the generation of documentation for the METS schema.
2. A new attribute, CONTENTIDS, with a new simpleType of URIs has been
to the <div>, <fptr>, <mptr> and <area> elements. This attribute has
primarily to simplify conversion between METS and MPEG21 documents, but
be useful for others wishing to associate URIs with specific portions
of a structural
map without having to link to identifier information in a <descMD>
3. The XLink namespace declaration has been changed to conform with
the W3C's XML Linking Language (XLink) Version 1.0 namespace
A new version of the XLink schema has been provided which also conforms
4. ID attributes have been added to the elements <FContent>,
5. "LOM" has been added as a metadata type in support of those using
archive courseware objects.
METS documents which declare the XLink namespace will need to be
use the new version of the schema; however, this change should resolve
problems experienced by those trying to employ the MODS schema with the
schema. Beyond that, existing METS documents should be compatible with
METS Profile Schema
1. An optional, repeatable <head> element has been added to the
model so that headings may be interspersed in any text section in a
2. A LABEL attribute has been added to the <Appendix> element to allow
addition of a machine-processable label/title for an Appendix.
