1 A Common Infrastructure for Digital Contents Vilas Wuwongse, Thiti Vacharasintopchai, Neelawat Intaraksa Asian Institute of Technology

2 Outline Introduction Issues Proposed Approach A Common Infrastructure Prototype Conclusion

3 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

4 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

5 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

digital library technologies The system interoperability problem can be alleviated by information service providers adopting

40 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.

41 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
