你可以通过将条目用属性与其他项或维基共享资源连接起来的方式反映现实生活中的声明。举个例子:有一个属性“子女”。你可以使用此属性在孙中山的项里添加一个她是孫科孫婉父亲的声明。还有一个可应用于他的“肖像”的属性是“图像”。使用此属性可以添加他在维基共享资源的肖像到孙中山项中。你可以给所有这些声明添加来源。你可以在截图中看到效果。

例子:

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.

语言独立原则

维基数据声明的概览
example of a simple statement consisting of one property-value pair
example of a statement consisting of multiple values for one property
example of a strong Wikidata statement consisting of one property-value pair, qualifiers, and a reference

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.

屬性

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.

多重值

If an item by nature can have properties with multiple values (like children of a person or official languages of a country), 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.

未知或无值

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.

多重值

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).

只加入可信信息

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.

简单多数和共识

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.

消歧義頁與其他非項維基媒體頁面

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.

消歧义页应只使用属性“instance of (P31)”-->“Wikimedia disambiguation page (Q4167410)”。

例子:

项:Madonna (Q1564372)
实体:Wikimedia disambiguation page (Q4167410)
项:list of lighthouses in Iceland (Q3253135)
实体: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.

收錄準則
