Ditto.
In general, I imagine that if we want to share/search date-related
information, we will have to treat dates either as a set of discrete
concepts, e.g.:
http://dbpedia.org/resource/1700
for the concept of the year 1700 A.D., or as a set of numeric values
along a time axis, as per the suggestions of Wolfgang Orthuber [1].
Personally, I would think we would get more value out of the first
approach, especially if we agree on mechanisms for expressing date
ranges using "concept" dates.
