MODS Version 3.2 changes

A new version of the MODS XML schema (version 3.2) is now available at :
www.loc.gov/standards/mods/v3/mods-3-2.xsd.

This replaces version 3.1, which was finalized in July 2005. Changes are minor in that there are additions and corrections that do not invalidate existing MODS 3.0 instances. The new version of MODS makes the following changes.

Under <location><url>:
- Added attribute "note" to allow for notes associated with the link. (Tentative plan for 4.0 is to make it an element instead of an attribute, and wrap <url> and <urlNote> together, but we can't do that in this version because it would not be compatible with 3.1.)
- Added attribute "access", enumerated list with values:
  preview
  raw object
  object in context
- Added attribute 'usage' under <url> with one enumerated value: "primary display".
Under <physicalDescription> <digitalOrigin> Added enumerated values:
- digitized microfilm (original source was microfilm)
- digitized other analog (original source was something other than the other enumerated values)
Under <part>

Added attributes ID, type, order
<part> may now be empty (minOccurs 0 on choice)

ID attribute added

to relatedItem (note that this was an error that has now been corrected; inadvertently omitted in version 3.1)
to note.

The following elements have been globalized:

<dateCaptured> (under <originInfo>) dateCapturedType defined
<edition> (under <originInfo>) editionType defined
<physicalLocation> (under <location>) physicalLocationType defined

Elements whose type had been assumed to be "string", but had not been explicitly typed, are now typed.
Added subelement <genre> under <subject>.
The schema location reference for xlink is changed to http://www.loc.gov/standards/xlink.xsd. (It was previously http://www.loc.gov/standards/mods/xlink.xsd. The schema now resides in both places so that earlier versions will not be affected, but it is now intended that the new copy be referenced, outside of the mods directory, so that other projects, e.g. mets, may reference it.)
