Calvin Hendryx-Parker gave a presentation on enabling the semantic web with RDF. He discussed how RDF allows data to be shared and integrated through graph-based triples. He also explained common RDF formats like RDF/XML and Notation3, and how RDF is used in applications such as FOAF, RSS, and Creative Commons to publish structured data on the web. Hendryx-Parker also provided examples of how RDF can be used internally in applications and content management systems to integrate data.
