You can find an exhaustive list of approaches adopted by data models to represent time points and time intervals in this work [1].

The XML Schema types [1] don't include a time interval format (unless you want to encode it as starting time + duration). There seems to be a way to encode it using ISO 8601, the Wikipedia says that intervals can be expressed as 'Start and end, such as "2007-03-01T13:00:00Z/2008-05-11T15:30:00Z"' [2], but I haven't found a formally defined datatype to use with RDF data. > > [1] www.w3.org/TR/xmlschema-2/ > [2] http://en.wikipedia.org/wiki/ISO_8601#Time_intervals > > Thanks for any help, > > Lars >
