As an FYI, ISO-8601 does specify a standard format for date and time intervals. It uses a forward slash and allows some shorthands: - 1980-07-01/1983-05-01 - 1980-07-01/07 (same as 1980-07-01/1980-07-07)
Not the prettiest, but it is a standard. https://en.wikipedia.org/wiki/ISO_8601#Time_intervals On Sun, May 6, 2018 at 3:28 PM, Tim Waters <[email protected]> wrote: > https://wiki.openstreetmap.org/wiki/Key:start_date#Approximations > > gives a number of such approximations with > > 1980-07-01..1983-05-01 as a suggested value. > > I seem to recall coming across a kind of bibliographic standard of all the > ways that dates can be encoded to capture fuzzyness, if I come across it > I'll add the info the page > > Tim > > On 6 May 2018 at 11:19, PauLL170 <[email protected]> wrote: > >> Hi, >> >> i'm already mapping Germersheim and a bit of Trier :) .
