The following ten important principles of CCO form
the foundation of this guide:
- Establish the logical focus of each Work Record,
whether it is a single item, a work made up of several
parts, or a physical group or collection of works.
Clearly distinguish between Work Records and Image
Records.
- Include all the required CCO elements.
- Follow the CCO rules. Make and enforce additional
local rules to allow information to be retrieved,
repurposed, and exchanged effectively.
- Use controlled vocabularies, such as the Getty vocabularies
and the Library of Congress authorities.
- Create local authorities that are populated with
terminology from standard published controlled vocabularies
as well as with local terms and names. Structure local
authorities as thesauri whenever possible. Record
and document decisions about local authorities.
- Use established metadata standards, such as the
VRA Core Categories or Categories for the
Description of Works of Art.
- Understand that cataloging, classification, indexing,
and display are different but related functions.
- Be consistent in establishing relationships between
works and images, between a group or collection and
works, among works, and among images.
- Be consistent regarding capitalization, punctuation,
and syntax. Avoid abbreviations, but when necessary,
use standard codes and lists for abbreviations (for
example, the ISO abbreviations for countries).
- For English-language information systems and users,
use English-language data values whenever possible.
