I understand that the before and after fields were intended, when a date is uncertain, how many precision units before or after the given date the real date could be. The precision units are: precision: shortint. The numbers have the following meaning: 0 - billion years, 1 - hundred million years, ..., 6 - millenia, 7 - century, 8 - decade, 9 - year, 10 - month, 11 - day, 12 - hour, 13 - minute, 14 - second. The calendar model presently is a URL that leads to a Wikibase item about the calendar. This seems adequate and I don't see a need to invent a letter code. The Wikibase items are multi-lingual, which qould be hard to achieve with a single letter. Currently the user interface converts multiple ways of writing dates into the ISO-8601. There's no need to store many different equivalent formats in the database. The calendars should probably be limited to different calendars, where the data contributors may not know how to transform from one calendar to another, rather than different formats for the same calendar. Other threads have expressed a need to convert all calendars to and from the Gregorian (possibly proleptic) calendar. So there should be no support for calendars where no one knows how to do the conversion (for example, the pre-Julian Roman Calendar).
