Data based automation
Metadata
is added to Web resources
they describe
properties
of the resource
W3C's RDF gives a unified format to do this
Metadata
vocabularies
(ontologies) can be developed
allows for logical reasoning on the metadata, eg
"if this property is true, then that property is true..."
"this property is that same as that property..."
etc
W3C develops a Web Ontology Language
Applications are based on analysing the metadata
eg, search engines
