Restina

Semantic Web Calendaring Agent "The Retsina Semantic Web Calendar Agent provides interoperability between RDF based calendar descriptions on the web, and Personal Information Manager (PIM) Systems such as Microsoft's Outlook. Schedules and events can be described on the web in RDF, using existing ontologies such as the Hybrid iCal-like RDF Schema or the Dublin Core ontology, and linked to individual's contact information described, for example, at their home page."
