Rutgers Digital Library Initiative

What is a Digital Library Initiative

• Employing digital technologies to support access, understanding and use of information by faculty and students to support the university’s core mission--research and education.

•Provide seamless, immersive access to information--our resources and the resources of others.


What is a Digital Library Initiative

•Insure a shared understanding of information, as well as its discovery and use.

•Support our users in all their roles: researcher, educator, publisher and learner

--a lifelong role!--a lifelong role!

•Provide core services to build a digital repository for RU information sources--both integrated and distributed


Design Principles•User-centered - user collaboration

•Supports Simple, transparent information use

•Customized for user roles and information needs

•Secure against misuse; intellectual property is appropriately safeguarded.


Design Principles•Sustainable -- collections and services are part of core mission. Core Applications suite supports addition of new archives and projects. Lifecycle of proposed projects are understood.•Distributed, flexible infrastructure that supports independence with integration across RU.•Seamless access to information and services

•Scalable - expansion not replacement, build forward rather than rebuild

Design Principles

•Core integration - common service suite


• Flexible data management - support heterogeneous metadata to support unique needs of information with a “core” that is understandable across all collections.

•Interoperable - based on open standards for collaboration and data exchange


The “Hybrid” Library

Goal: Seamless integration of analog and digital information.

•Ease of discovery and access regardless of format.

• Building designs that encompass inviting, immersive stacks

• Core integration through the metadatabase

University Information Model


Initial Steps: Build an Open-Architecture Repository Infrastructure

• Distributed, managed digital storage providing information that is durable and secure.

•Centralized database with data registry

• Open protocols that support sharing information across libraries and across campus:

Initial Steps: Build a Common Service Suite• Metasearch engine across collections

•METS structure map for defining parts, concatenating into collections, linking descriptive and technical information - database driven design

•Multiple display and export formats from structure map

•Core intellectual property management - collaboration with Internet2, CNI, ViDe and others


Initial Steps: Build a Common Service Suite•Metadata driven archives (“portals”) which support

data sharing within and outside RU.

• Open Archives Initiative implementation for sharing metadata--participating in other union catalog initiatives. Enabling our “information provider” users to share their metadata with their initiatives.

Role of Interoperability Protocols OAIOAI - Open Archives Initiative. HTTP-based protocol for simple searching and data mining across metadata repositories.

METSMETS - Metadata Encoding and Transport Standard- concatenates descriptive, administrative and rights metadata into an OAIS dissemination information package. Provides structure map for complex objects.

SCORMSCORM - Shareable Content Object Reference Model. Combines IEEE LOM metadata with run-time initialization to provide data objects that can be pulled into IMS applications for use in lesson plans, syllabi, etc.

Provides encoding and transmission of descriptive, administrative and structural metadata using XML

• Provides for transmission of metadata.• Associates structure map, file types

and behaviors with digital objects to provide “intelligent” complex objects - e.g. E-Journal with machine and human recognizable “table of contents,” “abstract,” “citation,” etc.

• Standard to create interoperable “learning objects”--can run on any compliant LMS/LCMS.

Model includes:• Required run time that compliant LMS must

support• required descriptive metadata - IEEE LOM

Z39.50: ANSI/NISO Z39.50-1995 (ISO Z39.50: ANSI/NISO Z39.50-1995 (ISO 23950):23950):

• Supports data exchange between repositories

• Supports federated searching by individuals across distributed repositories

•Client/Server computer-to-computer communications protocol that specifies query and retrieval of information: bibliographic data, full-text documents; images, and multimedia in a distributed network environment, across disparate computer systems, databases and search engines.


Synchronization between content and description

Creation of dynamic and “permanent” segments and clips

Non-textual indexing - melody and speech recognition, color, shape, scene changes, etc.

Textual format/Binary Format completely equal

Assessment Assessment - Understanding the “information ecology” at RU:

• How do core user groups use information for research and education activities?

• What are their information sources? What is RUL’s “market share?”

• What digital information do our core users create and manage? What potential digital information sources (analog, frequently nontraditional.”

Developing a Sustainability ModelDeveloping a Sustainability Model

• Maintaining a project or collection’s durability and usefulness -- “keeping our promise.”

• Developing “application suite” that enables RUL to create and manage digital collections/services and to integrate services created by others.

• Develop and document minimum “best practices” for the creation and management of digital collections

• Determine the “lifecycle” of a project via testbeds. Participate in testbeds.Participate in testbeds.
