RUcore ObjectivesRUcore 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

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
