List of all data types available

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

Literal data field for a string that is not translated into other languages. This type of string is defined once and reused across all languages. Typical use is a geographical names written in the local language, an identifier of some kind, a chemical formula or a Latin scientific name.

• language – explicit value for identifying the language for the text part – see Help:Monolingual text languages
• value – explicit value for the language specific variant string

Literal data field for a quantity that relates to some kind of well-defined unit. The actual unit goes in the data values that is entered.

• amount – implicit part of the string (mapping of unit prefix is unclear)
• unit – implicit part of the string that defaults to "1" (mapping to standardizing body is unclear)
• upperbound - quantity's upper bound
• lowerbound - quantity's lower bound

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

Literal data field for a point in time. Given as a date and time with some precision and boundaries. The time is saved internally in the specified calendar model.

• 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 4 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 identifies the calendar model of the timestamp.
