RDF Calendar taskforce

Last Modified: 2003-04-10, Libby Miller

The current focus of the RDF calendar work is on a syntactic conversion of iCalendar to RDF, and we recommend using the new RDF calendar schema (N3 version, test cases and examples) rather than older versions (e.g. the 'hybrid' version). The RDF calendar workspace links to fairly regular public IRC meetings on the topic, including logs, as well as testcases, converters and many other tools. Everything is announced to the www-rdf-calendar mailing list. There is a RdfCalendar wiki page on the ESW wiki.

Scope: Use www-rdf-calendar for detailed technical discussion of systems, vocabulary and scenarios relating to the use of RDF and XML with calendaring and scheduling tools on the Web. Please try to avoid crossposts with the other RDF lists. The focus of the list is on practical implementation work (testbeds, prototypes, collaborative development), although theoretical work (eg. on representations for events, time-periods etc) in RDF, XML, DAML etc. is in scope.

Taskforce description

The RDF calendar taskforce is an informal grouping of individuals interested in calendaring and scheduling, primarily in RDF. Through scenario-lead discussion by email and irc, the taskforce will aim to draft an RDF schema for calendar events. It will also aim to demonstrate the use of RDF in a calendaring and scheduling context.

There is a great deal of work being done in the IETF in this area in particular in the IETF Calendaring and Scheduling (calsch) working group, The taskforce will monitor that work; this monitoring will result in a list of calendar resources on the taskforce's homepage.

The taskforce is open to anyone interested in RDF calendaring and scheduling.
