  1. The Metadata Landscape: Cataloging Cultural Objects, the VRA Core, and Our Visual Collections Margaret N. Webster Knight Visual Resources Facility December 14, 2007

  2. Why the fuss about Metadata? • Access: find more stuff • Meaning: what is it? distinguish one thing from another • Context: where does it fit?, where will it lead? • Uses: who can use it and how they use it • Preserve: helps save stuff

  3. In the age of Google, why bother? • Speed up cataloging • Promote consistency of recording and retrieving data • Reduce user confusion • Facilitate migration fielded data can be recombined mechanically for a variety of outputs and uses • Useful in sharing initiatives • Improve user access

  4. Many Systems/Many Purposes • Content Management Systems • Image Collections • Libraries • Museums • DAMS • Digital Repositories • Course Management • Presentation/Discovery tools

  5. A digital object gathers metadata • Administrative • Technical • Preservation • Structural • Descriptive • Use plus user generated metadata!

  6. Descriptive Metadata A Brief Typology • Data structure standards (metadata element sets) VRA Core, CDWA, Dublin Core, MARC • Data value standards (vocabularies/taxonomies) LCSH, LCNAF, TGM, AAT, ULAN • Data content/syntax standards (cataloging rules) CCO, AACR (RDA), DACS • Data format/technical interchange standards (expressed in machine-readable form) VRA Core XML schema, CDWA-Lite, Dublin Core, DC Qualified XML schema,MARC, MARCXML

  7. Cataloging Cultural Objects:Issues Covered • Managing objects/images vs. describing them • Work Type, Classification, Naming works • Whole/part relationships • Controlled terminology • Contextual materials and relationships • Various audiences and display demands

  8. This simplified diagram illustrates how works may be related to other works, and how works may be related to images, sources, and authorities.

  9. CCO Ten Key Principles: Illustrated Examples

  10. 1. Establish logical focus of each work record…8. Be consistent in establishing relationships…

  11. Both are portraits of the same person, but are different work types painting photograph

  12. Example of 2 image records linked to 1 work record

  13. Example of records for related works

  14. 2. Include all of the CCO required elements.3. Follow the CCO rules. Make & enforce additional local rules to allow effective retrieval, repurposing and the exchange of information.

  15. CCO Recommended elements *

  16. 4. Use published controlled vocabularies such as the Getty vocabularies & the Library of Congress Authorities.5. Create local authorities that are populated with terminology as well as with local terms. Structure as thesauri whenever possible.

  17. Subject field using terms from various authorities

  18. Class: Architecture • Work Type: memorial • Title: Lincoln Memorial • Creator Display: architectHenry Bacon (American, 1866-1924) and sculptor Daniel Chester French (American, 1850-1931) • Creation Date: designed 1911-1912; constructed 1914-1922 • Subject: commemoration, honor, Abraham Lincoln • Location: Washington, DC • Materials and Technique: Exterior: Colorado Yule marble; Tripods: Pink Tennessee marble; Interior walls and columns: Indiana limestone; Ceiling: Alabama marble saturated with paraffin for translucency; Floor and wall base: Pink Tennessee marble; Pedestal and platform for statue: Tennessee marble; Statue: White Georgia marble • Description: Design was influenced by the Greek Parthenon. Built into the design are symbols of Union like the 36 exterior Doric columns representing the 36 states in the Union at the time of Lincoln's death… • Concept Authority Record: • Terms: • memorial (preferred) • memorials • commemoration building • Note: • Structures built to preserve the memory of beings or events. For other objects created, issued, or worn to commemorate persons or events, use "commemoratives." • Hierarchical position: Objects Facet • ....Built Environment • ........Single Built Works • ...........<single built works by function> • ...............<ceremonial structures> • ...................memorials • Source: AAT • Links to authorities are recommended • Authorities are discussed in detail in Part III of CCO

  19. 6. Use established metadata structure standards, such as the VRA Core Categories, CDWA….

  20. 7. Understand that cataloging, classification, indexing and display are different, but related things

  21. Display Cataloging Classification

  22. Creation Cluster

  23. 9. Be consistent regarding capitalization, punctuation and syntax, but when necessary use standard codes and lists for abbreviations…10. For English-language information systems and users, use English-Language data values whenever possible.

  24. Metadata on the move: mapping

  25. Metadata Practice • Tools for capturing • Community standards for sharing and reuse • Portable and Preserved • Workflow, when, who • Where to store? • Where and how to display
