The CDWA-Lite XML schema was created by three organizations to describe cultural works and their related information. It aims to provide core descriptive metadata for works while allowing flexibility in the level of detail provided. The schema includes 22 elements, with 19 for descriptive metadata, 3 for administrative metadata, and 9 required elements. It utilizes controlled vocabularies, XML syntax rules, and semantic elements. Records encoded in CDWA-Lite can be harvested through the Open Archives Initiative protocol.

one color, it calls

2. The CDWA (resource) was created as a structure to describe art work and
their accompany images that can be navigated to a database or via an
XML-scheme encoding scheme, promoting sharing of research records and
user access. CDWA was founded in the early 1990s by the Art Information
Task Force. The group is comprised of art and information professionals that
came together to create specific rules for describing art, objects,
architecture, textual information, and visual artifacts. The AITF was funded
by the J. Paul Getty Trust, the National Endowment for the Humanities, and
the College Art Association.
The CDWA-Lite XML schema was created by three organizations including
ARTstor, the J. Paul Getty Trust, and RLG Programs/OCLC to describe
artifacts, cultural entities, and their affiliates. “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 machinereadable format.

CDWA FRAMEWORK = 532 categories + subcategories
The CWDA Framework promotes the following: Compatibility |
Accessibility | Integrity of Data | Longevity of Data.
Intended Users: curators, information managers, systems
vendors, and registrars.

•“CDWA
Lite is an XML schema to describe core records for works
of art and material culture based on the Categories for the
Description of Works of Art (CDWA) and Cataloging Cultural
Objects: A Guide to Describing Cultural Works and Their Images (
CCO) (which uses a subset of the CDWA categories).”
“The purpose of this schema is to describe a format for core
records for works of art and material culture, based on the data
elements and guidelines contained in the CDWA and CCO. Like
VRA Core, CDWA Lite offers an XML format in which to store
metadata about works of visual culture in accordance with
CCO. CDWA Lite records are intended for contribution to union
catalogs and other repositories using the Open Archives Initiative
(OAI) harvesting protocol.”

Cataloging Cultural Objects
“… A guide to Describing Cultural Works and
Their Images (CC) includes rules and examples for
a core subset of the CDWA categories and the
VRA Core Categories.” The CCO is the third of four types
of data standards for the art and material cultures (it is the
dominant source used today). The guide is available in
hardcopy via their website for free.

VRA Core 4.
“A data standard for the description of images
and works of art and culture. The current version
of this standard is VRA Core 4.0, which features
two options for implementation: “unrestricted”
which defines the VRA Core data elements, and
“restricted” which enforces data constraints on
certain elements to predefined vocabularies or
date formats.” Quote By Archivists.Org Source:

8. A main characteristic of the CDWA Lite
format is the division of the descriptive
metadata in display elements on one
hand, optimized for presentation
purposes, and indexing elements
optimized for retrieval.

http://conference.ifla.org/past/2009/107-coburn-en.pdf
Indexing elements, they usually should
refer to authorities for actors, places, or to
controlled vocabularies, are provided
with attributes for storing a respective URI
(term source and term source ID), assuring
the identity of a term in a larger context.

10. METADATA RECORD Harvested CONTINUED….
This metadata record also had Indexing elements along with the display element.
“Indexing elements contain information that facilitates search and retrieval, in addition to
assisting aggregators with filtering and sorting search results. At the J. Paul Getty Museum, the creator
information largely comes from an artist authority file, which is then mapped appropriately to CDWA Lite
indexing and display elements,” (IFLA Conference, 2009)

*Provide core descriptive

However, it is up to the
provider of the data to
determine the information level
of high or low with regard to
how their record will be

CDWA-LITE XML Schema has 22 elements, 19 are descriptive

schema does have controlled vocabulary elements, uses XML
Syntax Rules, and has elements that consists of meaning with regard
to information objects.
