Outline Introduction Issues Proposed Approach A Common Infrastructure Prototype Conclusion
Introduction Advancement in hardware, software, networks Wide-spread use of Internet Lots of digital contents via Web 2.0 technologies One can be an author, teacher, singer, actor One can own a publishing house, radio/tv station
Issues (2) The problems described earlier can be categorized into three groups: the problem on metadata control and indexing the problem on digital content preservation the problem on system interoperability
Proposed Approach The metadata problem can be alleviated by information service providers adopting international metadata standards and cataloging their contents accordingly The preservation problem can be alleviated by organizations adopting digital library technologies The system interoperability problem can be alleviated by information service providers adopting open standards which allow information in repositories to be exchanged freely among participating organizations by means of metadata
A Common Infrastructure
Hybrid Library Library Automation Systems Digital Library Institutional Repository Books/ Journals in print Microforms CD-ROMs, etc. E-Books E-Journals/ E-Magazines Multimedia files, etc. E-Theses/ Dissertations E-Research/ Papers E-Courseware, etc. Hybrid Library Search via (only) one (interface) Retrieve (data) from several (systems) Integration of searching between library automation systems and digital library. 8
Hybrid Library : What they store? Library Automation Systems Stores bibliographic data of printed materials including microforms, cassettes, films, etc. Digital Library Stores electronic or digital data including texts, images, maps, audios, videos, illustrations, etc. Institutional Repository Stores intellectual assets of an institution as digital contents. 9

Conclusion Contents from repositories can be quickly utilized and published with the assistance of learning management systems and content management systems Opinions and discussions about contents can also be captured and archived back into the repositories for later reference Once adopted and deployed in large-scale, the Common Infrastructure for Knowledge and Information Management will play a crucial role in creating a universal source of knowledge for humanity.
Conclusion A software infrastructure has been proposed to commonly support the management of digital contents on the Internet and an intranet The infrastructure can be used to capture, preserve and manage digital contents that belong to communities and organizations so that they stay intact and do not vanish with time It allows pieces of knowledge in repositories to be located and shared effectively across boundaries within an organization or between organizations and nations through open standards
