In Wikidata, a concept, topic, or object is represented by an item. Each item is accorded its own page. A statement is how the information we know about an item—the data we have about it—gets recorded in Wikidata. This happens by pairing a property with at least one value; this pair is at the heart of a statement. Statements can also be expanded on, annotated, or contextualized with additional values, as well as optional qualifiers, references, and ranks. Statements also serve to connect items to each other, resulting in a linked data structure.

Language item property Стойност
английски Marie Curie occupation physicist
немски Marie Curie Tätigkeit Physiker
френски Marie Curie occupation physicien
полски Maria Skłodowska-Curie zajęcie fizyk
български Мария Кюри професия физик
  Q7186 P106 Q169470

Пример:

In order to include information about the occupation of Marie Curie in Wikidata, you would need to add a statement to the item for Marie Curie, Marie Curie (Q7186). Using the property, occupation (P106), you could then add the value physicist (Q169470). You could also add the value chemist (Q593644). Note how both chemist and physicist have their own pages in Wikidata, thereby allowing Marie Curie to be linked to these items.

A statement consists of a property-value pair, for example, "location: Germany."

The property in a statement describes the data value, and can be thought of as a category of data like "color", "population," or "Commons media" (files hosted on Wikimedia Commons). The value in the statement is the actual piece of data that describes the item.

Statements can also be expanded upon, annotated, or contextualized with the addition of optional qualifiers, references, and ranks.

Свойства

Each property in Wikidata is assigned a pre-defined data type which restricts what can be added as its value. For example, only other items can be added as a value for the property "color", only numbers can be added for the property "population," and only multimedia files viewable on Wikimedia Commons can be added for the property "Commons media."

For more information on how to use properties, please see Wikidata:Properties.

Стойности

Няколко стойности

Ако една страница включва свойства с няколко стойности (като деца на личност или официални езици на страна), it is perfectly acceptable to add them.

If on the other hand an item ideally should have only one value (like the population of a city) but has multiple values (for example, because different sources report different numbers), all values may be added and additional qualifiers should be used. Qualifiers are used to further describe or refine the value of a property given in a statement. Please see Help:Qualifiers for more information.

Неизвестни стойности или без стойност

There are times when an item has either no value or an unknown value for a given property. Depending on the property, these data values still provide important information about an item and should still be recorded in Wikidata. For example, we could say that Elizabeth I of England (Q7207) had no value for the child (P40) property, which is quite different than not recording anything at all. We could also say that William Shakespeare (Q692) has an unknown value for the date of birth (P569) property.

The majority of values in Wikidata will be custom values, and are entered in the usual fashion. Unknown values and no values are added to statements by clicking on the icon beside the value field that looks like this Wikidata snak icon.png.

Quantitative values

When adding quantitative values the following constraints should be noted. The largest positive integer number that Wikidata allows is 9e124+-0 and the largest negative number -9e124+-0. For floats one additional decimal place is supported 9,9e124+-0, but 9,91e124+-0 is not possible. The smallest positive and negative numbers are 1e-124+-0 and -1e-124+-0. For floats the exponent can only be 123 making this the smallest positive and negative floats: 1.0e-123+-0 and -1.0e-123+-0 (Note that the zero will be preserved as an indicator of the precision of the value. Compare this to entering 1e-123+-0).

Add only verifiable information

Wikidata is not a database that stores facts about the world, but a secondary knowledge base that collects and links to references to such knowledge. This means that Wikidata does not state what the population of Germany actually is; it simply provides the information on what the population of Germany is according to a specific source, such as the The World Factbook (Q11191) CIA World Factbook.

As such, most statements should be verifiable by referenceable sources of information like a book, scientific publication, or newspaper article. In Wikidata, references are used to point to specific sources that back up the data provided in a statement. For more information, please see Help:Sources.

Plurality and consensus

Because statements essentially point to referenceable sources of information and different sources may provide contradicting information, it's possible to represent a plurality of perspectives on Wikidata.

In case of disputes, community consensus determines the value of a property, however other points of views can be added as additional values as long as they include a source and appropriate qualifiers. Ranks can also be used; if a consensus exists, it should be indicated by a preferred rank. For more information on ranks, please see Help:Ranking.

Please note that disputes should be discussed on the item's discussion page. Edit warring over values is not acceptable.

Пояснителни и други non-item Wikimedia страници

When a Wikidata item refers to a Wikimedia page itself rather than to the subject of the Wikimedia page, the instance of (P31) property should be used to identify the type of page. This includes Category, Template and other pages outside the main namespace.

Всички пояснителни страници на елементи трябва да имат изявлението 'instance of (P31)' 'Wikimedia disambiguation page (Q4167410)'.

Примери:

страница: Madonna (Q1564372)
инстанция на: Wikimedia disambiguation page (Q4167410)
страница: list of lighthouses in Iceland (Q3253135)
инстанция на: Wikimedia list article (Q13406463)

Where a Wikipedia page covers more than one concept, object or thing use 'has part (P527)' to link to separate Wikidata pages for each of the individual concepts, objects or things.

Exclusion criteria

Wikidata statements should be sourced and contain trustworthy neutral references.

The following types of information should not be added as Wikidata statements:

Добавяне на изявления

Изявленията се добавят към дадена страница на елемент — в примера по-долу, за Marcel Bouix (Q16775650) — по следният начин:

Навигирайте до секцията « Изявления » (или « Statements » на английски)
Изберете « добавяне » (или « add » на английски) в дъното на всички други изявления
В новопоявилото се поле за свойство (« property » на английски), започнете да пишете свойството
Изберете свойството от предложените възможности
В новото поле от дясно на свойството, започнете да пишете стойността. Когато сте готови натиснете « съхраняване » (или « save » на английски)
Въведеното свойство ще се появи по показаният начин. За да го промените или изтриете, натиснете « редактиране » (или « edit » на английски)

To add qualifiers, sources, or ranks, please see the appropriate help documentation listed at the bottom of the page.
