Digital Asset Management at the University of Washington Libraries:Teamwork and Technology Greg Zick, Professor, Electrical Engineering Director of Center for Information Systems Optimization, University of Washington Betsy Wilson, Director University of Washington Libraries Geri Bunker Ingram, Head, Library Systems Department University of California, San Diego Jill Fluvog, Project Manager, CISO University of Washington
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 • Side-by-side text for multi-page documents with search capability within document
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
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
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
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 HTMLfile to web page for course development or colleague for review
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
