What Led to the Web's Success?

q



Simple architecture - HTML, URI, HTTP Networked - value grows with data, services, users Extensible - from Web of documents to ... Tolerant - even w/ imperfect mark-up, data, links, software Universal - independent of systems and people Free / cheap - browsers, information, services Simple / powerful / fun for users - text, graphics, links Open standards ...

Why are Open Standards Important?

q



Broad industry agreement (if done right) Interoperability ... cross-application, -organization, -data Avoids vendor lock-in ... for providers and users Open access = no black boxes Mandated ... by customers, government Open, royalty-free standards = good business sense

Semantic Web: Why?

q



Tasks often require combining data across the Internet, e.g.:

r



Integrating data across the enterprise Hotel, transport, meeting, personal info come from different sites Mining data from biochemical, genetic, pharmaceutical, patient databases Cross-referencing disparate digital libraries



r



r



r



q



Humans understand how to combine this information ...

r



Not always easy (different vocabularies, languages, formats)



q



Machines aren't smart enough :-)
