The standard organizations such as the World Wide Web Consortium (W3C) and Dublin Core Initiatives have directed major efforts at specifying, developing, and deploying standards for metadata. These efforts certainly march a crucial step to promote wide spread deployment to enhance data functionality and interoperability, for example, FOAF (metadata for friends), SKOS (metadata for taxonomies), DOAP (metadata for project), RSS or ATOM (metadata for news), SIOC (metadata for social networks), Dublin Core (metadata for documents), GEO (metadata for geographic coordinates), GeneOnt (metadata for human genes), microformat (metadata for Social Web) and so on.

This course aims to provide an introduction to metadata from the semantic web point of view. It emphasizes the semantic perspectives of metadata with the focus on data integration and mediation. This course contains three parts: Part 1 is the introduction of the basic semantic web technologies which include ontology, RDF and OWL. Part 2 provides the detailed analysis of the selected metadata, such as FOAF, SKOS, RSS (ATOM) and so on. Part 3 introduces some popular domain ontologies, such as bibliographical ontologies, multimedia ontologies, geo location ontologies and general ontologies (Linked Open Data ontology (YAGO) and Wikipedia Ontology).

After the course, the students should be able to:
  • Be familiar with important metadata schema and be able to deploy them into real life applications
  • Be familiar with popular domain ontologies and be able to use them to represent data and semantics
  • Develop an understanding of the semantic web technologies
