Digital Library Issues


Massive quantities of media items



Rapidly evolving technologies



Structured, semi
-
structured, unstructured and multimedia data



Frequent modification of collections to support expanding and
additional projects



Diverse user community with different characteristics,
preferences, and capabilities

Goals of UW Libraries/CISO
Collaboration


Make media resources available electronically to an audience
of:


Faculty


Researchers


Schools


Community groups


Build online media databases to provide access to Special
Collections and manage scholarly information

45 collections with 40,000 items currently
online or in development

Background of Collaboration


Began in 1996 between Libraries, Electrical Engineering’s
Center for Information Systems Optimization and campus
faculty


Collections stored in multitude of forms and locations


Demand building on and off campus for better access to media
items


Balance necessary between demand for open access,
protection of rare archived materials, and technology options


Commercial tool not identified and CISO was conducting
research into optimal digital database technologies


Partnership formed with Libraries identifying archival and
access requirements and CISO responding with technology

Collaboration Outcomes


Successful online collection development


Development of the CONTENT Software Suite for digital
asset management


Ongoing transformation of Libraries’ focus to embrace
dramatic changes in information archiving and access

CONTENT Software Suite for
digital asset management


Builds and manages multimedia collections on the Web
and links media files with finding aids


Scalable for small collections


Optimized for speed in large dataset delivery


Supports incremental collection building process


Administrative interface offers terms and tools familiar to
librarians and collection owners


Search interface provides “friendly” Web
-
based access for
broad user community

Collaboration Outcomes:
New CONTENT Features


Enhanced full resolution indexing for archival purposes


Support for multi
-
page documents and 3
-
D media items


Authenticated Vocabulary for consistency and quality in
metadata entry


Support for Dublin Core qualifiers

Collaboration Outcomes: Evolution


UW Libraries Digital Collections are “work in progress”
with new collections being added continuously


Outreach activities extending lessons learned to other
organizations


Libraries offering leadership to partners in state and local
community


Faculty and teaching now supported in new way

Building online digital collections:
Capturing Media


CONTENT supports numerous media types
-

images,
documents, audio clips, video segments


Acquisition Station facilitates capture in multiple modes


Single images imported from any directory


Sets of images added in batch input mode


Template defined for repeating fields


Import of existing metadata from other programs via
export/import of delimited ASCII files

Acquire images from scanners and other TWAIN
devices

Import single items or batches of items

Use Template Creator for repetitive field data

Building online digital collections:
Organizing Collections


Spreadsheet View provides “fill” capability to repeat field
descriptions


Media Editor allows single item metadata entry with
Authenticated Vocabulary



Ships with LOC Thesaurus for Graphical Materials


May customize or use existing vocabulary file


Items may be combined and defined as “postcards” (front
and back), “picture cubes” (six sides) or multi
-
page
documents

Spreadsheet View

Media Editor Form with Authenticated Vocabulary

Building online digital collections:
Managing and Administering Collections



Server Administrator and Collection Administrators are
identified for each server/collection


All administration may be done from a browser
-

anywhere


Server Administrator sets up new collections and
authorizes Collection Administrators


Collection Administrators add new items, edit collections,
set up full resolution scan support and customize
description fields (hidden, searchable…)

Building online digital collections:
Defining Descriptive Fields


Critical step when indexing collection materials


CONTENT supports unlimited number of fields


Allows collection expert(s) to define names as
relevant to discipline and audience


Results in more effective searching, particularly in
large archives

Metadata Fields

Building online digital collections:
Searching Across Multiple Collections

Challenge arises in searching multiple collections with different metadata


CONTENT provides mapping function and collection owner defines
how unique fields will be related to other collections


Example:

Two collections searched for city “Olympia”


Results retrieved from both collections


Original descriptions maintained


Owners have mapped specific fields to Dublin Core (“city” in one and
“location depicted” in another are mapped to “coverage”)


Default mapping is qualified Dublin Core
-

other standards (e.g. VRA)
can be used


Description fields defined independently as searchable, hidden, and/or
with an Authenticated Vocabulary

HTML Search
Client:

Search across
multiple
collections for
“Olympia”

Building online digital collections:
Collection Expansion

Lesson learned: digital collections spawn more collections


Distributed Acquisition Stations support geographically
remote partnerships


Administrator maintains integrity through “gatekeeper”
functions


Washington example:


State Library funding collaborative collection development
featuring local digitization, indexing, then online availability via
the University of Washington Libraries server


Supports collection owners with limited IT (or non
-
existent) resources

Building online digital collections:
Setting Up Collections for Searching


HTML client accessible by anyone with a browser


Campus and community users have access regardless of
size/cost of their system (network speed a consideration…)


Access is extremely fast: Design goal to retrieve results
from million item collection in < 1 second


JAVA client serves users with powerful machines and
specific requirements


Workbox allows user to organize sets of images


Workbox contents may be sent as HTML

file to web page for
course development or colleague for review

JAVA Search

Building online digital collections:
Setting Up Collections for Searching

Lesson learned: End users have varied interests, backgrounds
and searching experience


CONTENT’s HTML Query Building Tool allows
collection owners to “pre
-
define” likely queries, tailored
for intended audience


Queries then built into Web pages to provide customized
interface


Example:

UW Digital Collections Klondike goldrush
photographs by Eric Hegg


Set up for use by broad audience (including classrooms)


Descriptive icons and mouse “rollovers” integrate queries into
Web page


Queries may search across multiple collections

Conclusions and future:

UW Libraries Impact and Direction


Digital Collections group extending impact of
collaboration


On campus: partnership with Center for Teaching and Learning
Technology offering digital tools to more faculty


Off campus: partnerships with local museums, public libraries
and historical societies


Vision:

Development of rich regional multimedia archives
integrating digital media resources and accessible by broad
range of users.



Libraries’ role:

Serve as catalyst by sharing cataloging and
collection expertise and leading “best practices” exchange

Conclusions and future:

Evolving Technology


CONTENT’s goals:



Be responsive to real problems of professional
archivists and respond with features and functions for
state
-
of
-
the
-
art archival support


Provide scalable offering allowing groups to start on
small scale with prototype projects and expand
collections after thoughtful review



Listen to users (now installed in diverse organizations
internationally) and
never

stop collaborating
