RUcore Objectives

• To provide seamless, perpetual access to digital
  collections -- our resources and the resources of
  others.
• To develop a flexible framework of core
  capabilities providing the enabling
  infrastructure, interoperability, and
  sustainability.
• To create an information architecture which will
  support multidisciplinary collections.

Institutional Repositories

• Institutional Repository
• . . . a set of services that a university offers
  to the members of its community for the
  management and dissemination of digital materials
  created by the institution and its community
  members. Clifford Lynch
• Types of Materials Deposited in Repositories
• Theses/Dissertations
• Pre-prints/post-prints
• Digital images
• Assets from Special Collections
• Technical reports/working papers
• Data sets

Information Architecture The Collection, the
Digital Object, and Metadata

• In its most general sense, a digital collection
  is simply a grouping of objects according to some
  criteria.
• Types of digital collections in Rucore
• Explicit A digital collection whose object
  membership is specified explicitly within the
  descriptive metadata.
• Dynamic A digital collection of objects which
  are grouped according to user specified criteria.

The Digital Object

• The digital object is the basic unit of
  management, encapsulating all essential
  information about the document to be
  disseminated and preserved, including
• Descriptive metadata (based on MODS),
  administrative and event-based migration metadata
• Byte streams in both presentation and archival
  formats (non-proprietary, infrastructure
  independent forms)
• Persistent IDs and digital signatures
• Software for dynamic behavior
• Metadata Object Description Schema

Data in a Multidisciplinary Repository

• Data Characteristics
• Born-digital, no corresponding physical artifact
• Specialized metadata standards DDI, FGDC, etc.
• Large gigabytes ranging to terabytes
• Life cycle changes versions, editions,
  re-purposing, etc.
• Many contributors, spread over wide-area network
• Users from many different disciplines

Continuing Directions(for Rutgers University
Libraries)

• Multidisciplinary Collections
• Provide faculty repository services (focus on
  data)
• Mapping to different metadata standards
• Institutional Repository
• Support Fedora Preservation Services Working
  Group
• Develop a trusted repository seek certification
• Develop partnerships sharing data and software

A Trusted Repository

• is one . . .that establishes methodologies for
  system evaluation that meet community
  expectations of trustworthiness
• Capabilities for a Trusted Repository (from
  Fedora Working Group)
• Signature/Checksum creation and validation
• Object format validation
• Content model validation
• Audit trails and versioning
• Event logging and alerting for preservation
  services
• Enable Repository static/active states
• History service of major repository events
