1. LIBR 281 - Assignment 3
Tracy Guza
The Seattle Public Library Century 21 Collection :
Balancing Metadata Complexity, Processing
Expediency and User Experience
3. Century 21 Collection
Over 1000 photographs plus all manner of
ephemera (menus, posters, maps,
guidebooks, nifty stuff)
Photos depict art and architecture as well
as documenting aspects of the 1962
Seattle World’s Fair
5. Statement of Problem
Images : capturing photographer
information as well as artist/architect,
medium, size, etc. information
VRA Core scheme allows for description
of the image and the work itself using
element set
7. Background
Resources
Three librarians work on digital collections
One cataloging librarian dedicated to Special
Collections
One part-time student librarian
8. Research Question
What are the optimal metadata elements
required to capture the richest descriptive
information on the Century 21 collection
while balancing processing expediency?
Will the metadata mix provide ample
retrieval for users?
9. Literature Review : Image Project
VIUS/Penn State
Grant-funded project to develop a digital image
system
“Super element set” with DC, VRA Core and
some specific admin data for ILS
Ultimately, they chose CONTENTdm and
mapped all elements to Dublin Core
10. Literature Review : Image Project
Cornell University
Faculty collections, three initial collections
including images of ancient Greek inscriptions,
anthropological research from Peruvian Andes
and South Asian architecture
VRA Core 4.0
Luna Insight collection software
Workflow, metadata quality - arduous!
Issues with controlled vs. local vocabulary
11. Literature Review : Image Project
Colorado Digitization Project
Union catalog merged diverse metadata from
participating organizations (EAD, MARC, DC,
VRA)
Dublin Core chosen as common denominator
Created and used local vocabulary lists
12. Literature Review : Resources
Greene and Meissner’s MPLP
Level of processing complexity should be in
accordance with staffing abilities and balance
detail with expediency
User access is paramount
13. Literature Review : Interoperability
Many articles with the bottom line that one
must consider the end use - i.e. harvesting
via OAIster, OCLC when planning
metadata elements
DC wins again
Issues with mapping DC to OAI to MARC
14. Collection Review : UW
Collections feature similar images, include
architect field which maps to dc.creator
CONTENTdm = flat
VRA Core = relational
Dublin Core common denominator
XML = happy interoperability
16. Final Metadata
Subject
LCSH used
Local controlled vocabulary with architects
Description
Can include more details on contractors and
engineers
Browse by
Helps users sort materials by building, topic
17. Discussion
Desire for immediate access,
interoperability and use of CONTENTdm
Collaboration on metadata collection
Other supplementary tools - subject guide,
architect spreadsheet, maps
