University Information Model



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



Design Principles•Supports Simple, transparent information use

• Customized for user roles and information needs

• Secure against misuse; intellectual property theft

• User-centered - user collaboration


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.”



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



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



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

• Extend core services across the university

• Dynamic personalized web spaces to support information discovery and collaboration (AMIA Moving Image Gateway Project)

Moving Forward



“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



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.)



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

Metadata Repository




Open Standards for Interoperability; TransportZ39.50 Application Service Definition and Protocol SpecificationClient/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)



Open Standards for Interoperability; TransportRDF – 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;

http://www.w3.org/TR/PR-rdf-syntax/


Open Archives Initiative

Metadatabase

Data mining – repository to repository; user to repository




Open Standards for Interoperability; TransportSOAP – Simple Object Access Protocol

Combines XML envelope with programming layers that are stripped off, as appropriate, at each hop.

Potential application – Digital Rights Management

www.w3.org/TR/SOAP/



Open Standards for Interoperability; TransportXML – 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/



Open Standards for Interoperability; TransportMETS – 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/



Open Standards for Interoperability; TransportSCORM – 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

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



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?



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



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 R&D – tomorrow’s core?

• Workflow analysis – project development vs. project management. Commonalities between core and R&D



The Digital Initiative in Context

• Strategic training

• Continuous evaluation – stand alone and in-context



Customer Support is Key
