Abstract

A simple vocabulary for generic start times, end times, start date-times, end date-times, and duration.

All terms at a glance

Properties: duration | endDateTime | endTime | startDateTime | startTime

Overview diagram

This vocabulary contains five datatype-properties for start time and end time (with range xsd:time), start date-times and end date-times (with range xsd:dateTime), and duration (with range xsd:duration).

Any value of these properties should be asserted to have the corresponding datatype, and should abide by the syntax for that datatype.

With the exception of duration, it is highly preferable (but not necessary) for times and date-times to have a specified timezone. Timezones are not necessary for duration.

If you want to specify a simple start date and end date, please use start date-times and end date-times with the time T00:00:00, preferably adding a suitable time-zone.

Currently, the xsd:duration range of nocal:duration is not formalised by the vocabulary. This will be added shortly.
