Web site targeted to NLSI needs: VIVO
  • Collaborative, scholarly initiative of librarians across Cornell
  • Provides well annotated, organized info on:
    • bibliographic resources
    • biology/bioinformatics databases
    • Cornell life sciences: people, research, courses, services/facilities, events/activities
  • Encourages faculty/research staff collaboration across Cornell

How is VIVO Different?
  • No fixed collection


  • Does not mirror organizational structure


  • Provides context for information


  • Fluid:
  • - will go in directions we cannot now anticipate


  • - adapts to content domains beyond our control
15
What Does this Gain Us?
  • Simplicity – everything displays consistently


  • Context – categorized browsing and searching


  • Fluidity - users can roam, not just drill down


  • Flexibility to grow and change in response to content and use

 Nuts and Bolts
  • Design Requirements
  • Sustainability
  • Ontology underpinnings
  • Strategies for moving forward
  • General applicability
18
Design Requirements for VIVO
  • Lightweight
  • Flexible
  • Extensible
  • Sustainable
  • Compliant with standards
  • Amenable to automation
19
Sustainability
  • Accessibility – immediate curator feedback
  • Granularity – not too detailed
  • Quality – commitment to get it right
  • Flexibility – ability to adapt
  • Proactive alignment with emerging standards/registries/shared resources in the library and life sciences communities
20
Phase One Approach to Updating
  • Downloading recent publications
  • Cultivating departmental contacts
  • Emailing “review your entry” solicitations to individuals
  • Dead link checking

Properties are Relationships
31
Vivo Entity and its Property Relationships
32
Relationship Glut
  • How do you avoid an unmanageable tangle of property relationships among so many classes?
33
Connect Only What You Need To
  • Following the W3C OWL model:
  • Properties are defined between specific classes
  • Properties are inherited by subclasses but not necessarily switched on
34
Adaptive Structure
  • Data are added to the site in response to interest and leads
  • Curators add more types and relationships to support differentiation where entries accumulate
  • The scaffolding adapts to areas of greater structural load
35
VIVO as a Harvestable Resource
  • Becoming an OAI-PMH service provider
    • Selection by type of entity
    • Selection by property/relationship based on DC, MODS, or any preferred standard


  • VIVO web services
    • Search response with name, type, and URL
    • Further options
      • Additional context
      • Inferencing results
      • Provenance or annotations
36
Extending Vivo
  • Filtering
    • By major subject area, college, campus
  • Improved searching
    • Augmenting terms via a choice of external thesauri
  • Distributed editing
    • Departmental liaisons
    • Templates to populate relationships
  • Export
    • RDF, METS
    • Preservation, pruning, and migration
  • Visualization


37
Generalizing VIVO
  • Modular design
    • Clone with or without ontology
  • Harvester and harvested
    • Expose metadata from multiple digital library collections in a coherent, accessible framework
  • Collaborations
    • With other aggregations of metadata
    • With domain-specific resources
