I'm surprised that you missed all this: I have considerable experience of marking up dates in microformats, [...] for historic events, on Wikipedia and Wikimedia Commons. [...] Use-cases for machine-readable date mark-up are many: as well as the aforesaid calendar interactions, they can be used for sorting; for searching ("find me all the pages about events in 1923" — recent developments in Yahoo's YQL searching API (which now supports searching for microformats): <http://developer.yahoo.net/blog/archives/2009/01/yql_with_microformats.html> have opened up a whole new set of possibilities, which is only just beginning to be explored). They can be mapped visually on a "SIMILE" <http://simile.mit.edu/timeline/> or similar time-line. They can be translated into other languages more effectively than raw prose; they can be disambiguated (does “5/6/09" mean “5th June 2009? or “6th May 2009"?); and they can be presented in the user's preferred format (I might want to see “5th June 2009"; you might see “June 5, 2009" — such presentational preferences have generated arguments of little-endian proportions on Wikipedia). hCalendar microformats are already used to mark up imprecise dates ("June 1977"; "2009") [...] Surely the use case for marking-up a sortable table of Roman emperors, should allow all such emperors, and not just those who ruled from 0001AD, to be included? in my original post. -- Andy Mabbett
