updated CmpE 583 Fall 2008 Discussion: Principles- 3 Which Browser for Semantic Web? Interfaces Semantic Web Browsers An HTTP URI with no fragment (#whatever) should generally identify a contribution to the web, a collection of knowledge. It probably has an HTML rendering, which is that knowledge put in a form that's easy for humans to understand. It should also have a structural (RDF) form, which is easy for humans and machines to understand. On good sites, with good browsers, the HTML will become more and more useless. A URI with a fragment identifer is taken to denote an object described in the knowledge base identified by the base URI.... A Semantic Web browser needs (1) an identifier of the thing you want information about, or the collection of things, or the collection of information, and (2) a configuration of what sources to use and what algorithms to use to find more sources, and (3) info about how to store changes you make, (4) appearance preferences. Legacy Browser Because both kinds of browsers use the same addresses for similar things, operation of legacy browsers is possible but tricky. The obvious approach is to say that every SemWebID should get the same info in human- readable form when Accepting what legacy browsers accept. That can be difficult. Another approach is to have the HTML generated by something like SemWalker, a server-side semantic web user interface. Or have the HTML view redirected/proxied to SemWalker.

updated CmpE 583 Fall 2008 Discussion: Principles- 4 Concern: Semantic Web (continued) Semantic Web Browser In your opinion, when semantic Web will have been realized:  What will happen to HTML? Will it dissappear?  What about legacy browsers?  Can the legacy & SW browsers coexist?  Why & how?  Other issues?

updated CmpE 583 Fall 2008 Discussion: Principles- 5 Topic: Semantic Web enabled e-Library The integration of E-learning, Intelligent Learning Infrastructures, Business Intelligence and Knowledge Management in libraries and information services. A special emphasis is on information systems and the challenges that the Semantic Web poses to Library operation. New services, dynamic exploitation of content, provision of knowledge intensive services, ontological engineering. Any examples?
