What is RUcore?o An institutional repository, to
preserve, manage and make accessible the research and publications of the university, its faculty and collaborators
o The cyberinfrastructure for the Rutgers University Libraries, for making its unique collections permanently available.

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

Why Create RUcore Now?
o Expanding digital environment creating information “stovepipes” at RU
o Technologies available to create a “trusted repository” architecture that makes information accessible for the long-term
o Granting agencies requiring permanent, sustained access to research products
o Natural extension of the libraries’ role in the university

Rutgers University Libraries
o Preservation: making resources available for the long-term. Can scholars access the information in 200 years?o Publishing: sustaining digital publishing models that incorporate the publisher’s business rules, such as peer review
RUcore Focus Areas:
o Collections: providing collections of value to scholarso Research & Teaching: support the twin missions of the university and integrate RUcore into the workflow of RU faculty

“Trusted Repository” architecture
o Is the digital object authentic?
o Can the digital object be uniquely identified and retrieved?
o Does the metadata support management, discovery and reuse?

Authenticity -- integrity “digital document must be whole and undisturbed”
--provenance – must be tightly associated with its creator and act of creation
Gladney and Bennett. What do we mean by authentic? http://www.dlib.org/dlib/july03/gladney/07gladney.html
In the analog space
Object in hand is compared with a conceptual (“canonical”) historical version

Creating our Digital Cultural Heritage
Authenticity
o In the digital space
-- Fidelity to the source artifact
-- Identical (true/false) to the digital
canonical master
--accompanied by a “true” provenance
statement
--Proof: digital signature verifying that canonical object is unchanged. Digital audit trail documenting provenance and any changes to artifact or chain of provenance

Durability – Preserving the Digital Cultural Heritage for Future Generations
Methodologies for addressing “digital permanence”
o Preserve the “digital mediation space”—hardware and software needed to access, manipulate and display the resource
o Emulate the “digital mediation space”. Recreate obsolete technology platforms, perhaps encapsulated in newer technologies
o Re-encode the information in new formats before the old format becomes obsolete
![Page 11: Rutgers University Libraries What is RUcore? o An institutional repository, to preserve, manage and make accessible the research and publications of the](https://reader036.vdocuments.mx/reader036/viewer/2022062320/56649d445503460f94a20939/html5/thumbnails/11.jpg)

Enabling Strategy
Technical metadata that documents the object’s creation, technical characteristics and required mediation space. Enables digital archive managers to manage large numbers of objects:
o checking for changes in the object (“digital provenance”)
o monitoring the digital format and mediation requirements to adapt to changing technologies (“technical metadata”)
o and maintaining connection to the source object (provenance and characteristics), so that as technology advances to offer greater fidelity to the source, objects can be re-encoded

Metadata
o Data about data. Has meaning with respect to the object it describes or manages
o Flexible to support current and future information contexts: discovery and management

Three-Year Collection Development Plan:
o Primary Research Products: particularly those that are useful for further research but difficult to discover and obtain: multimedia research products, data sets, etc.
o Resources created by administrators and publishers that have research value beyond the administering department
o Significant special collections from RUL

Tools, Guidance, Workflow and Business Model
o Tools: workflow management system (current). “Digital depot”, “data center” and Sakai interface planned.
o Guidance: Digital standards, metadata guidance, equipment to create high end digital objects
o Business model: flexible core services, participation in grants, integration of repository services into library repertoire.
