Web Services
Ontologies
MarkUp Languages

4. Web Services A software system identified by a URI
Its public interfaces and bindings are defined and described using XML
Its definition can be discovered by other software systems
These systems may then interact with the Web service in a manner prescribed by its definition, using XML based messages conveyed by Internet protocols

5. Semantic Web
An extension of the current web in which information is given well-defined meaning
An abstract representation of data on the World-Wide Web, based on RDF
It is being developed by the W3C, in collaboration with a large number of researchers and industrial partners
Machine readable and processable

10. Conclusion
OWL-S developed on top of XML, will facilitate the transition
Agent markup languages will enable search engines to go beyond Boolean searches and use natural language instead
RDF will help integrate and aggregate applications to make the Web more like a library cataloge
