Subject: [CNI-ANNOUNCE] CDWA-Lite Call for Public Review

CDWA-Lite is a lightweight XML schema that describes core
information
for cultural materials and their visual surrogates.  It is
described
below.

The Advisory Committee for this standard is seeking broad
community
review of it from a technical viewpoint as well as for its
value in
collection cataloging and access/sharing.  We encourage
completion of
the survey (or those parts of it you are comfortable with)
at
http
://www.surveymonkey.com/s.asp?u=625603692421

While the survey will provide the most useful basis for
review,
additional comments outside the survey are welcome at
cdwalitegetty.edu.

Please respond before 31 May 2007.  We anticipate a
discussion of the
results of this review in conjunction with the MCN meeting
in Chicago, 7
- 10 November 2007.

Summary:

Over the last two years ARTstor, the J. Paul Getty Trust,
and RLG
Programs/OCLC have worked together to develop an XML schema
to describe
cultural materials and their surrogates to provide an easier
and more
sustainable model for contributing to union resources.  This
initiative
was driven by the absence of a data content standard
specifically
designed for unique cultural works, and a technical format
for
expressing this data in a machine-readable format.

The result of this effort is CDWA Lite, an XML schema based
on the core
elements from Categories for the Description of Works of Art
(CDWA), a
framework for documenting and organizing information on
cultural works
and images.  CDWA Lite is intentionally *lightweight,* to
encourage
and facilitate its use even by small institutions in
cataloging, online
publishing, and exposing metadata.

The schema recommends using Cataloging Cultural Objects
(CCO), a data
content standard for unique cultural works that provides
guidelines for
selecting, ordering, and formatting data used to populate
elements. It
is designed to promote good descriptive cataloging, shared
documentation, and enhanced end-user access.  CDWA Lite was
specifically
designed for use with the OAI Protocol for Metadata
Harvesting
(OAI/PMH), which is a standard for delivering, sharing, and
disseminating metadata records expressed in XML syntax.

CDWA Lite is made up of 22 descriptive and administrative
elements, of
which only 9 are required; it is not meant to be a
comprehensive element
set for describing or cataloging works in a collection. 
Instead, a CDWA
Lite record contains the minimal amount of relevant and
critical
information needed for facilitating ease of access to unique
cultural
works in the online environment.  CDWA Lite reflects the
core
descriptive documentation traditionally captured about works
in
collections, which makes adoption of this model for
contributing records
to union resources all the more attainable.

CDWA Lite intends to meet the following objectives:

-	To provide a simple, low-barrier model for capturing the
essential amount of information about unique cultural works
in order to
facilitate a high return on accessibility and resource
discovery. The
minimal set of information needed to facilitate ease of
access to
collections.
-	To reduce the overhead and labor involved in contributing
to
aggregated resources and digital repositories. Format and
export data
one time only in a standards-based way for contribution to a
variety of
*venues* in the online environment.
-	To ensure a method for being able to provide updated,
accurate
information about works of art that are accessible in the
online
environment.  Data integrity and accuracy occurs at the
source of the
collection.
-	To provide a mechanism for bringing users back to a
resource in
its native environment.  Learn more about a work in the
context of its
larger collection.

The Advisory Committee will organize a public meeting to
discuss
responses to the CDWA Lite survey and other feedback
received from the
community during the MCN conference in November 2007, which
will take
place in Chicago.
