Title: Managing Digital Initiatives


1
Managing Digital Initiatives
Changing University Landscape
  • Personalized consumer-driven information
    culture
  • Highly competitive
  • Increasingly cooperative
  • Continuously innovative
  • Blurring roles instructor, learner, publisher

Managing Digital Initiatives
Design Principles
  • Scalable - expansion not replacement, build
    forward rather than rebuild
  • Core integration - common service suite
  • Flexible data architecture - support
    heterogeneous metadata to support unique needs of
    information
  • Interoperable - based on open standards for
    collaboration and data exchange
  • Robust and Secure 24/7 availability,
    maintaining

4
Managing Digital Initiatives
Design Principles
  • Supports Simple, transparent information use
  • Customized for user roles and information needs
  • Secure against misuse intellectual property
    theft
  • User-centered - user collaboration

5
Managing Digital Initiatives

Creating a Digital Playground
  • Boundaries to create an integrated, rich
    information space with a multiple common services
  • Within those boundaries - customization,
    personalization - everyone can play.

6
Managing Digital Initiatives
The Hybrid Library
  • Goal Seamless integration of analog and digital
    information
  • Building designs that encompass inviting,
    immersive stacks and analog materials use areas
    improving circulation workflow
  • Core integration of analog and digital through
    the metadatabase

7
Managing Digital Initiatives
Build a Common Service Suite
  • Metasearch engine across collections
  • METS structure map for defining parts,
    concatenating into collections, linking
    descriptive and technical information - database
    driven design
  • Multiple display and export formats from
    structure map
  • Core intellectual property management -
    collaboration with Internet2, CNI, ViDe and
    others

8
Managing Digital Initiatives
Build an Open-Architecture Repository
  • Distributed, managed, secure digital storage
  • Centralized metadatabase with data registry
  • Security mechanisms for data storage and user
    access
  • Treat all information resources as
    mission-critical with common security
    infrastructure and peering or failover procedures

Managing Digital Initiatives
Moving Forward
  • Extend core services across the university
  • Dynamic personalized web spaces to support
    information discovery and collaboration (AMIA
    Moving Image Gateway Project)

11
Managing Digital Initiatives
Intelligent Information Portal
  • Simple search interface (Google model)
  • Blend description with reference evaluation
  • Intelligent metadata that self-describes by
    portal
  • Partner with other departments for development
  • Different results for different user roles
    (Intenet2 Commons)
  • Personal portal create collections,
    components, search strategies, searchable,
    standardized dynamic site map

12
Managing Digital Initiatives
The Metadata Repository

  • Core registry that maps to reference schema RU
    Core
  • Schema, language and character set independent
  • Enables self-describing of data by portal
    identifier (e.g. education data elements for
    education portals, etc.
  • AMIA MIG model separate tables for portal ID
    and for each data element, with extensive
    attributes (lang, charset, portalID, etc.)

13
Managing Digital Initiatives
The Role of Metadata
  • Bring intelligence, coherence to digital
    collections and the fragmented web
  • Selection, organization, preservation,
    discovery, interpretation
  • Enable the creator and the customer to make sense
    of digital information.
  • Active collaboration with the customer in this
    enterprise

Open Standards for Interoperability Transport
  • Z39.50 Application Service Definition and
    Protocol Specification
  • Client/Server computer-to-computer communications
    protocol that specifies query and retrieval of
    information bibliographic data, full-text
    documents images, and multimedia in a
    distributed network environment, across disparate
    computer systems, databases and search engines.
  • Current version 3
  • http//lcweb.loc.gov/z3950/agency/document.html
  • Resource Description Framework (RDF)

16
Managing Digital Initiatives
Open Standards for Interoperability Transport
RDF Resource Description Framework
Enables interoperability among metadata schemes,
including the modular use of multiple schemes
within a metadata record utilizing the XML
namespace facility Adds machine-interpretable
semantics to the encoding, exchange and reuse of
structured metadata

19
Managing Digital Initiatives
Open Standards for Interoperability Transport
  • XML Extensible Markup Language
  • A data exchange and markup language with
  • inherent semantic meaning for elements
  • ability to combine programming with data,
    particularly with XSLT
  • transport and interoperability protocol

www.w3.org/XML/
20
Managing Digital Initiatives
Open Standards for Interoperability Transport
  • METS Metadata Encoding Transmission Standard
  • Enables concatenation of metadata records and
    schema for description, administration, rights,
    etc
  • Enables interoperable structuring of complex
    objects (multi-page document, sequential video
    file, etc., for search and retrieval within
    structures, across documents

http//www.loc.gov/standards/mets/
21
Managing Digital Initiatives
Open Standards for Interoperability Transport
  • SCORM Shareable Content Object Reference Model
  • Provides IMS (instructional metadata standard)
    description for educational objects
  • Enables SCORM-compliant objects to be imported
    and exported into compliant instructional
    management systems (WebCT, Blackboard, etc.
  • Coming structuring into lesson plans and
    syllabi

Managing Digital Initiatives
Sustainability
  • Collections and Services support core mission
    and primary strategic goals
  • Build a distributed, shared infrastructure with
    core standards and technologies actively
    partner across the organization

23
Managing Digital Initiatives
Evaluating Sustainability
  • Interval and impact of initiative 1 year, 5
    years, 10 years value to institution as a whole
    and to key stakeholder groups
  • Project Evolution Path initiation,
    development, maintenance, enhancement,
    completion. How do we know when the useful life
    has ended?

24
Managing Digital Initiatives
Evaluating Sustainability
  • Coexistence dependent, neutral, or
    competitive with other initiatives and ongoing
    services.1 year, 5 years, 10 years value to
    institution as a whole and to key stakeholder
    groups

25
Managing Digital Initiatives
The Digital Initiative in Context
  • Identify core (mission-critical) activities.
    What percentage of effort/time do they require
    ---should they require? (workflow analysis
  • What percentage of time/effort remains for RD
    tomorrows core?
  • Workflow analysis project development vs.
    project management. Commonalities between core
    and RD

26
Managing Digital Initiatives
The Digital Initiative in Context
  • Strategic training
  • Continuous evaluation stand alone and
    in-context

27
Managing Digital Initiatives
Customer Support is Key
  • Support for New Roles
  • Information Seeker
  • Information Publisher
  • Lifelong Learner
