As of Drupal 7 will use RDFa markup in core, in this session I will:

• explain what the implications are of this and why this matters
• give a short introduction to the Semantic web, RDF, RDFa and SPARQL in human language
• give a short overview of the RDF modules that are available in contrib
• talk about some of the potential use cases of all these magical technologies
