The MOD Editorial Committee and the Library of Congress is
pleased to announce that a new incremental version of MODS, version 3.5, is now
available on the MODS website at: http://www.loc.gov/standards/mods/v3/mods-3-5.xsd.
This revision is backwards compatible to version 3.4 and
therefore only includes changes that do not result in invalidating existing
MODS records. A new major revision of MODS to make more substantive changes is
currently under discussion. MODS
implementers may want to use this revised version to take advantage of its new
features. The changes are as follows:
- Added attribute @unit in
mods:extent. This change makes the extent element more granular by separating units from
- Added rfc5646 as value for
<language><languageTerm> . Enumerated values reflect earlier standards; RFC5646 has superceded RFC4646.
- Added @altFormat and
@contentType attributes to <titleInfo>, <abstract>,
<tableOfContents> and <accessCondition>. This change allows for embedding HTML in MODS, linking with @altRepGrp, and
indicating the format of the alternative encoding.
- Added @eventType under
<originInfo> to indicate production, publication, distribution,
manufacture. This attribute allows for indicating what type of event the statement of
originInfo relates to, e.g. production, publication, distribution, manufacture,
or some other event.
- Added @typeURI on
<identifier>, <note>, and <physicalDescripton>/<note>. This change allows for indicating that a type is in the form of a URI.
- Added @generator on
<classification>. The value of this attribute indicates that the classification number was
automatically generated and, if appropriate, how.
- Added<etal> element, a
subelement of <name> . The <etal> subelement is added to the list of <name> subelements to
indicate that there are one or more names that, for whatever reason, cannot be
explicitily included in another name element.
- Added @otherType to
<titleInfo> element. This allows for designating another type value for titleInfo that is not on the
list of types enumerated in the schema.
For further information and examples see:
Revised versions of the MODS User Guidelines, the MARC to MODS mapping, and the
XSLT conversion that incorporate the 3.5 changes will be available on the MODS
web site soon.
Please direct any comments or questions on the MODS 3.5
Schema, or MODS/MADS developments in general, to the MODS Listserv <http://listserv.loc.gov/listarch/mods.html>.
