Is there a standard (recommended) datatype to use when I want to specify a time interval (e. g. 2013-11-13--2013-11-14)? 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.
