List of properties with this data type

Globe coordinate

Literal data for a geographical position given as a latitude-longitude pair in gms or decimal degrees for the given stellar body. Defaults to "Earth" and then "WGS84". It adds a resolution and range.

  • latitude – implicit first part (float, dms, dm, dd) of the coordinate string, direction is either given by prefixed sign or by postfixed N/S
  • longitude – implicit second part (float, dms, dm, dd) of the coordinate string, direction is either given by prefixed sign or by postfixed E/W
  • globe – explicit (?) data value, given as stellar body that defaults to Earth "http://www.wikidata.org/entity/Q2"
  • precision - numeric precision of the coordinate

Time

Literal data field for a time value. Given as a time with some precision and boundaries. The time is always saved internally in the Proleptic Gregorian format, but can use other formats during parsing and formatting.

  • time – explicit value for point in time, represented as a timestamp resembling ISO 8601, e.g. +2013-01-01T00:00:00Z. The year is always signed and padded to have between 1 and 16 digits.
  • timezone – explicit value as a signed integer. Timezone information as an offset from UTC in minutes.
  • before – explicit integer value for how many units after the given time it could be. The unit is given by the precision.
  • after – explicit integer value for how many units before the given time it could be. The unit is given by the precision.
  • precision – explicit value encoded in a shortint. The numbers have the following meaning: 0 - billion years, 1 - hundred million years, ..., 6 - millennium, 7 - century, 8 - decade, 9 - year, 10 - month, 11 - day, 12 - hour, 13 - minute, 14 - second.
  • calendarmodel – explicit value given as a URI. It will identify the calendar model that should be used to display this time value.
