I have made changes to https://www.mediawiki.org/wiki/Wikibase/DataModel#Dates_and_times. Perhaps you could review my changes to see if you agree. One element of the TimeValue structure, //calendartime//, seems to be redundant so long as only the Gregorian and Julian calendars are supported. If we followed the original plan of using ISO 8601, this element would have been a useful place to store the converted value, but now I don't know what it's for. Perhaps if we supported the Roman calendar (which preceded the Julian calendar) we could use it to preserve an exact date such as "ninth day before the Kalends of Octobera in the consulship of Marcus Tullius Cicero and Gaius Antonius" for the birth date of Augustus; since exact conversions of Roman calendar dates are not possible, the //time// element could be used to indicate date in a specified proleptic calendar with an appropriate precision, In any case, I think a better description of the community's vision for the use of //calendartime// should be give so people don't stuff the database full of their own private idea of what ought to go there.
