RDF Calendar Taskforce
ABSTRACT
This presentation will discuss an approach to calendaring and scheduling in XML/RDF. It will cover a brief history of Internet Calendaring and Scheduling, including the ISO 8601 connection and the interoperability issues arising from diverging standards. The presentation will conclude with an XML-RDF scheduling demonstration (simple).
A number of RDF Interest Group participants have recently shown interest in applying RDF to calendaring and scheduling and have formed a taskforce to look at these issues under the umbrella of the W3C's semantic web activity.
The taskforce plans to work on a modular and extensible RDF schema for calendar and schedule data. A major aim is to create a calendar format representation in XML/RDF drawing on initiatives such as the IETF's iCalendar work in the CALSCH group, and the SKICal initiative. The group will evaluate the RDF representation of XML schema datatypes recently proposed by the DAML initiative in creating this RDF/XML representation.
A goal will be to explore syntax neutral representations so that existing iCalendar data can be queried alongside related meta information. One example of this might be combining scheduling information about a meeting and its attendees with documents, whitepages, and working group administration information.
Another goal is to create demonstration applications which use RDF in a calendaring context. An example is to use the RDF vocabulary to annotate event-orientated RSS 1.0 newsfeeds and build enhanced RSS aggregators to support date-based queries.
The presentation will discuss some of the difficulties of time/date syncronization across diversely syntaxed platforms, and demonstrate prototypes for querying across calendar data and other meta information.
