- Digital Libraries: history, definition, characteristics, architectures
- Kahn/Wilensky Framework and its derivatives
- The lecture for Week 5 will focus on what is known as the Kahn-Wilensky
Framework, and some its derivatives and implementations. Most DL projects
began in an ad-hoc, bottom up fashion that facilitated quickly providing
access to large stores of information. Kahn & Wilensky provide a strong,
consistent, and extensible framework for storing, managing and accessing
digital objects. The KWF will provide the basis for the next generation
of productions DLs. As such, knowledge of the KWF will allow us to
provide a more thoughtful critique of the upcoming DL case studies.
- Robert Kahn and Robert Wilensky, "A Framework for Distributed Digital
Object Services," cnri.dlib/tn95-01, May, 1995.
This is the original document outlining what has become known as the
Kahn-Wilensky Framework. No implementation issues are discussed, but many
key concepts and terms are introduced. A working understanding of this
document is necessary for a significant remainder of the class.
- W. Y. Arms, "Key Concepts in the Architecture of the Digital Library",
D-Lib Magazine, 1(1), 1995.
This is a contemporary companion paper for the KWF and more clearly
illustrates the concepts.
- C. Lagoze and D. Ely, "Implementation Issues in an Open Architectural
Framework for Digital Object Services", Cornell CS Dept
TR95-1540, September 12, 1995.
This document discusses some of the design concepts introduced in the KWF and
provides a treatment that is one step closer toward implementation.
- C. Lagoze, R. McGrath, E. Overly and N. Yeager, "A Design for
Inter-Operable Secure Object Stores (ISOS)", Cornell CS Dept TR95-1558
November 27, 1995.
This document is another iteration in the design process of KWF issues.
Its discussion includes proposed CORBA implementation.
