Typ danych określa sposób zachowania deklaracji i rodzaj pobieranych danych. Różne typy deklaracji używają różnych typów właściwości, a także używają różnych typów danych. Podczas tworzenia właściwości jednym z wyborów jest ustawienie typu danych, a po ustawieniu właściwość zostaje zablokowana dla tego typu danych. Ma to wpływ na sposób ich wykorzystania i musi istnieć w planach pewna ich liczba, zanim będzie można zdefiniować użyteczną właściwość.

Koordynacja prac nad właściwościami odbywa się na stronie Wikidata:Property proposal.

Właściwości według typu

For a list of the properties that currently require each type of data type, see either:

Lista typów danych

Commons media

type: commonsMedia (Commons media file)
list of properties: Category:Properties with commonsMedia-datatype -- Special:ListProperties/commonsMedia

References to files on Wikimedia Commons. During entry in the textfield the "File" namespace on Commons will be searched for matching entries. These files can be used both to illustrate the concepts in Wikidata and as an actual property value for inclusion on Wikipedia.

Examples:
  • Wikidata-logo.svg

Globe coordinate

type: globe-coordinate (Geographic coordinates)
list of properties: Category:Properties with globe-coordinate-datatype -- Special:ListProperties/globe-coordinate

A geographical position given as a latitude-longitude pair (in gms or decimal degrees) for a given "globe" (any stellar body). Globe defaults to "Earth" (globe: http://www.wikidata.org/entity/Q2). A "precision" parameter describes the resolution of the source of the coordinate. Note that the coordinate system is assumed to be "WGS84" (World Geodetic System 1984 (Q11902211)), which may not be suitable for less Earth-like bodies, and this is not configurable.

Currently, the Web UI of Wikidata doesn't expose all parameters of this data type. The value is visualized only as the coordinate, plus an embedded map if the globe is Earth (Q2). The precision can be modified in the edit mode. The globe is not visible, nor editable, in the item view. The full configuration is however visible in the history diff view (example).

It is possible to edit the data in full via API. The CLI tool is one way to access the API. In this example Olympus Mons (Q520) is given a coordinate on Mars (Q111) using the globe parameter (used in coordinate location (P625)):

wd ac Q520 P625 '{ "latitude": 18.4, "longitude": 226, "precision": 0.016666666666667, "globe": "http://www.wikidata.org/entity/Q111" }'

The globe.js script adds a UI to set the globe parameter of coordinate location (P625).

Bots such as LocatorBot may detect when the globe parameter of coordinate location (P625) is not set according to located on astronomical body (P376). Adding located on astronomical body (P376) and waiting for a bot to update the coordinate globe is an accepted workaround.

Item

type: wikibase-item (Item)
list of properties: Category:Properties with wikibase-item-datatype -- Special:ListProperties/wikibase-item

Link wewnętrzny do innego elementu.

Property

type: wikibase-property (Property)
list of properties: Category:Properties with wikibase-property-datatype -- Special:ListProperties/wikibase-property

Link wewnętrzny do właściwości.

String

type: string (String)
list of properties: Category:Properties with string-datatype -- Special:ListProperties/string

Łańcuch znaków, cyfr i symboli, które nie muszą być tłumaczone na różne języki lub formaty liczb. Ciąg znaków nie jest używany do obliczeń.

Examples:
  • B123
  • 90928390-XLE
  • u29238

Monolingual text

type: monolingualtext (Monolingual text)
list of properties: Category:Properties with monolingualtext-datatype -- Special:ListProperties/monolingualtext

A string that is not translated into other languages. This type of string is defined once and reused in all languages. Typical use is a geographically localized entity name written in the local language, an identifier of some kind, a chemical formula or a latin scientific name. See Help:Monolingual text languages for information about the language codes available for monolingual text values and how to request support for additional language codes. (Note that monolingual text also implies a single script system, which can make the string somewhat problematic.)

External identifier

type: external-id (External identifier)
list of properties: Category:Properties with external-id-datatype -- Special:ListProperties/external-id

String that represents an identifier used in an external system. Will display as external link if a formatter URL (P1630) is defined. See: External identifiers.

Quantity

type: quantity (Quantity)
list of properties: Category:Properties with quantity-datatype -- Special:ListProperties/quantity

A Quantity value represents a decimal number, together with information about the uncertainty interval of this number, and a unit of measurement. The attributes are:

  • amount: the quantity's main value
  • lowerBound: the quantity's lower bound (optional)
  • upperBound: the quantity's upper bound (optional)
  • unit: unit of measure item (empty for dimensionless values)

Internally, amount, lower bound and upper bound are strings; positive numbers are stored with a plus sign, though this will not be displayed. The representation of a quantity may not be longer than 127 characters; therefore, the maximal value of a quantity is 10^126-1.

Konwersja jednostek nie została jeszcze wdrożona (11 października 2015).

The normalisation table is readable as a JSON file in the WMF Mediawiki repository.

Examples:
  • 762 (dimensionless)
  • 2500 km (upper and lower bounds are not set, with unit)
  • 1.03 ± 0.02 g (enter as nominal value +/- tolerance, representing a lower and upper bound, with unit). The tolerance is in some cases not shown at Wikipedia, only the nominal value, for example in Wikidata lists produced by the listeria bot.

Time

type: time (Point in time)
list of properties: Category:Properties with time-datatype -- Special:ListProperties/time

Ten typ danych przechowuje datę w kalendarzu gregoriańskim lub juliańskim. Zobacz szczegółową strukturę.

Examples:
  • 2012
  • 1780-05 (=maj 1780)
  • 1833-11-1 (=1 listopada 1833)

URL

type: url (URL)
list of properties: Category:Properties with url-datatype -- Special:ListProperties/url

A generalized "URL" that identifies some kind of external resource, perhaps a link to an external site of some kind, or an identifier used for lookup in some kind of specialized resource.

Data types that will never be implemented

Changing datatype

A property in "string" datatype may be converted to "external identifier" datatype by a system administrator. To propose such a change, you may start a discussion at the talk page of the property or Project chat. After a consensus, a request may be made in Contact the development team. You should read previous discussion if you want to convert a property created before 2016.

Other changes of data type requires creating a new property and deleting the old one. You should use Properties for deletion for such requests.
