Summary
Currently, resources on the World Wide Web are primarily available for display purposes to humans.
The vision of the Semantic Web is to organize and link this information such that it becomes processable by computer applications.
With data stored in RDF, we can define classes and properties that categorize and describe the data (RDF Schema). We can further describe these classes and properties by specifying relationships between classes and properties, equality and inequality, and cardinality (OWL).
From the data we know (RDF), and the rules that are defined (RDFS and OWL), we can make inferences to discover new information.
