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 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

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

  • 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

Data in a multidisciplinary repository

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

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

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
