By the end of this class, the student should be able to:

• List the semantic web goals;
• Identify the semantic web technologies and characterize their scope;
• Describe the RDF model: graph of statements about resources, with subject, predicate and object;
• Relate RDF graphs with their serialized versions in XML;
• Describe the classes and properties of RDF-Schema;
• Query ontologies using the SPARQL language;
• Identify key concepts of the domain of the dataset under study;
• List some features of the Protégé tool for ontology editing.
