W3C's Semantic Web in Heath Care and Life Sciences Interest Group is bringing together many leading bioinformaticists and life scientists to solve a very wide array of data expression/integration problems in terms of modeling, unifying and querying biological data. This work is founded upon the full suite of W3C Semantic Web technology standards that work together to provide a rich semantic toolbox for software and system developers.

This tutorial will present an introduction to many of the W3C Semantic Web technologies. We will motivate the introductions with use cases and case studies taken from the health care and life sciences domains. The tutorial will also be presented against the backdrop of the creation and querying of the HCLS interest group's Knowledge Base.

The tutorial will cover the following technologies:

• RDF (data model)
• RDFS (schema language)
• OWL (ontology language)
• SPARQL (query language)
• GRDDL (XML to RDF)
• RDFa (embedding RDF in HTML)
