This is a list of all datatypes currently in use on this installation:
Item

Link to other items at the project. During entry the "Item" namespace on Wikidata will be searched for matching entries. It consists of a single text entry field.

  • scheme – implicit part of the Iri-string
  • hierarchicalpart – implicit part of the Iri-string
  • query – implicit part of the Iri-string
  • fragment – implicit part of the Iri-string
Commons media

Link to files stored at Wikimedia Commons. During entry the "File" namespace on Commons will be searched for matching entries.

  • scheme – implicit part of the Iri-string
  • hierarchicalpart – implicit part of the Iri-string
  • query – implicit part of the Iri-string
  • fragment – implicit part of the Iri-string
String

Literal data field for a string of glyphs. Typical use are identifiers that have written forms which do not depend on the language of the reader.

  • value – explicit value for the language specific variant string
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 per ISO8601, the year always having 11 digits and the date always being signed, in the format +00000002013-01-01T00:00:00Z
  • 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 - millennia, 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.
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
  • altitude (optional) – explicit (?) value for the height over a reference plane , for the globe "Earth" that would be the "WGS84" reference globe
  • globe (optional) – explicit (?) data value, given as stellar body that defaults to "Earth" and then "WGS84"
