Course SWEB101 - Introduction to the Semantic Web - RDF, RDFS, OWL and Ontologies

Duration: 5 Days

Intended Audience

This course is aimed at semantic web ontology content designers, architects, and developers who need to understand the concepts and technologies underpinning the Semantic Web. Attendees are expected to have some familiarity with XML.


The emphasis of this course is on providing an understanding of the various problems involved in building semantic web applications and how they have been addressed by RDF, RDFS and OWL. The course also covers issues involved with knowledge engineering issues associated with Ontology building, and reasoning over Ontologies using reasonsers based on Description Logics (DLs). The course will introduce the Semantic Web Query Language SPARQL (SPARQL Protocol and Query Language) as well as SWRL (Semantic Web Rule Language) and SQWRL (Semantic Query-Enhanced Web Rule Language).
