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.
Rutgers Digital Library Initiative
What is a Digital Library Initiative
•Insure a shared understanding of
information, as well as its discovery and use.
•Provide core services to build a digital repository
for RU information sources--both integrated and
distributed
•Support our users in all their roles:
researcher, educator, publisher and learner
--a lifelong role!
Rutgers Digital Library Initiative
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.
Rutgers Digital Library Initiative
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
Rutgers Digital Library Initiative
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
Rutgers Digital Library Initiative
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

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:
Creating a shared, “virtual” collection of university
information providers.

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
Rutgers Digital Library Initiative
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.
OAI is a core “middleware” interoperability protocol
required by NSF and other granting agencies.

Role of Interoperability Protocols
ALCTS
 OAI - Open Archives Initiative. HTTP-based protocol for simple
searching and data mining across metadata repositories.
 METS - Metadata Encoding and Transport Standard- concatenates
descriptive,
administrative and rights metadata into an OAIS
Nov. 2002
dissemination information package. Provides structure map for
complex objects.
 SCORM - 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.
 Z39.50 - Data Exchange and Transport Protocol
Slide 12
 MPEG-7 - Multimedia Content Description Interface

Open Archives Initiative Protocol (OAI)
G. Agnew
Nov. 2002 Metadata record mining using OAI protocol
commands imbedded in HTTP (GetRecord,
ListRecords)
Service providers pull records from data
providers for union catalog implementations
Limited set definitions and limited flow control
Requires Archives ID, Record ID, and
datestamp

Rutgers Digital Library Initiative
METS:
Metadata Encoding & Transmission Standard
G. Agnew
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.
Rutgers Digital Library Initiative
SCORM - Shareable Content Object Reference Model
G. Agnew
• 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
application profile
• Structure map for complex objects (“SCOs”)
• Simple sequencing specification
Rutgers Digital Library Initiative
Z39.50: ANSI/NISO Z39.50-1995 (ISO 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.
Rutgers Digital Library Initiative
MPEG-7 Multimedia Content Description Interface
 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
