维基数据是一个人人皆可编辑的知识库。在你开始之前,让自己熟悉维基数据词汇表是个好主意。这样,编者们便能“用上同一门语言”(可以这么说)。我们希望这有助于改进编者之间的讨论交流

Glossary
Alias (also also known as) is an alternative name for an item or property. The usual or most important name is the label. Aliases help people to find an item even if they don’t search with the label. For example, the item Q60 has the label “New York City” and aliases such as “NYC” and “The Big Apple”.
Help:Aliases
Badges are optional markers that can be attached to a sitelink. For instance a sitelink can be marked to link to a "featured article" and/or to a "proofread" page.
Help:Badges

字符串是一个普遍使用的术语,用来指一个任意选取字符构成的序列,且被解析为文本(如“你好”)——与之对应的是一条被解析为数值的数据(3.14)、到其他项的链接(如[[Q1234]])或一个更复杂的数据类型(集{1,3,5,7})。维基数据将支持数据类型“单语言文本”和“多语言文本”,两者都被视为串数据类型及属性

Constraint is a rule how a particular property should be used. For instance each instance human should only have one date of birth (P569), so there is a single value constraint on this property.
Help:Constraints
Datatype (data value type or value type) is the kind of data values that may be assigned to a property, and specifies how the data values are stored in each claim. Each property is assigned a pre-defined datatype. Not all values can be linked, as long as there are certain datatypes missing. The development of new datatypes is still in progress. See also Special:ListDatatypes for currently available datatypes.
Help:Data type
Description is a language-specific descriptive phrase for an item, property or query. It provides context for the label (for example, there are many items about places with the label "Cambridge"). The description therefore does not need to be unique, neither within a language or Wikidata in general, but it must be unique together with the label. Uniqueness for a combination of a label and a description is a hard constraint. If your contribution does not meet this requirement you cannot save the change.
Help:Description

实体(在[$1 维基数据用户界面信息]中有时称为数据集)是维基数据页面中的数据内容,且可以是一个(在主名字空间)、属性(在属性名字空间)或查询(在查询名字空间)。每个实体都由一个实体ID唯一确定,它是一个有前缀的数,例如项是前缀Q起始、属性是P而查询是U。一个实体亦可由各语言中唯一的标签描述的组合区分出来。还可为实体分配一组多语言的别名。(在本体和作为维基数据中的参考存在图书馆编目中,一个实体一般是现实生活一个话题或主题,或它在数据库中的表示,并且与之匹配的那个背景下维基数据中的的事物被称为一个

External identifier Some properties have values that are strings used in the databases of external organisations. They uniquely identify an item. For example, an ISBN for a book or the unique part of the URL of a movie or an actor in the Internet Movie Database.
Item refers to a real-world object, concept, or event that is given an identifier (an equivalent of a name) in Wikidata together with information about it. Each item has a corresponding Wikipage in the Wikidata main namespace. Items are identified by a prefixed id (like Q5), or by a sitelink to an external page, or by a unique combination of multilingual label and description. Items may also have aliases to ease lookup. The main data part of an item is the list of statements about the item. An item can be viewed as the subject-part of a triplet in linked data.
Help:Items
Label (also name) is the main name given to identify an entity (i.e. an item or a property). E.g.: the item with the item identifier Q7378 has the English label “elephant”. Every entity has exactly one label in a given human language. Other than entity identifiers, labels do not need to be unique. Descriptions and aliases are used to distinguish between entities with the same label. Wikidata pages do not have labels, but titles.
Help:Labels
Language attributes are the language-specific labels, aliases and descriptions that are assigned to items, properties and queries. These are human-readable text to improve understanding of the scope of the item; for example the specific type of real world entity. If they are missing some of them can be replaced by strings from alternate languages, following the language fallback chains.
Language fallbacks (also language chains) are methods to systematically replace missing language attributes with strings from alternate languages. The exact replacement rules can be chosen depending on the type of page, whether the user is logged in, or the user preferred languages.
Mainspace is one of the namespaces in a wiki. Other than other namespaces, it does not have a prefix. In Wikidata, the mainspace contains the pages with the items.

MediaWiki 是一种自由软件,并且是所有Wikimedia项目的基础。因为该软件是自由的,目前它拥有不同实体的数千个安装实例;相关详情请参见MediaWiki是什么

Meta pages These are all pages that are not entities, i.e. do not belong to the data namespaces. Wikidata meta pages contain unstructured content represented by conventional MediaWiki code, and perhaps also future Wikidata client side inclusion code. Examples are talk pages, category pages, project pages (in the Wikidata namespace) and help pages (in the help namespace). Meta pages also comprise content and data automatically generated by the MediaWiki software (for example, the edit history of a page, or special pages).
Namespaces are a kind of category for pages in a wiki. Per namespace you may have different rules about the pages and their content. In Wikidata, the most important namespace (or ‘main namespace’) is for the Wikidata items. The URL of such a page ends on a Q with a number, for example Q7378 for “Elephant”. The pages in other namespaces start with the namespace name, the ‘prefix’, for example Help:Contents.
Help:Namespaces
Page An internal or external webpage with a unique title, for example an article in Wikipedia main namespace or an item in Wikidata main namespace. In Wikidata, the term "page" may refer to an item or a property page in the data namespaces, a meta page in other namespaces or an external linked page on Wikipedia or other Wikimedia site or an other external site, that is referenced using a sitelink. Pages in the main namespace of Wikidata are about items, and one page can only hold one item.
Project is a term often used in the Wikimedia movement. In most cases, people mean a Wikimedia Wiki. So in Wikidata, the term usually refers to Wikidata itself.
Property (also attribute) is the descriptor for a data value, or some other relation or composite or possibly missing value, but not the data value or values themselves. Each statement at an item page links to a property, and assigns the property one or several values, or some other relation or composite or possibly missing value. The property is stored on a page in the Property namespace, and includes a declaration of the datatype for the property values. Compared to linked data, the property represents a triplet's predicate.
Help:Properties
限定符声称的一部分,它们明确了关于某个声称的一些事项,通常以一种描述性的方式。一个限定符可以是一个词汇表中的术语但也可以是不同的描述性短语(这些术语或短语是任意文字还是一定是某个词汇表的一部分取决于维基数据社区)。
Help:Qualifiers
Query is a search across items in Wikidata. By now queries can be executed in the SPARQL query language. It is planned to extent Wikidata by queries as entities defined on their own pages.

等级是一个质量系数,在给定属性有很多声明时,用于简单的选择/过滤这些声明。有三种可能的等级:


Help:Ranking
Reference (or source) describes the origin of a statement in Wikidata. A reference is often an item in its own right; for example, a book. Wikidata does not aim to answer the question of whether a statement is correct, but merely whether the statement appears in a reference.
Help:Sources
Site is a reference to an external website in general, but in sitelinks it refers to specific registered wikis, for example a Wikipedia language version. Those sites are referenced by global site identifiers or for short siteid, technically corresponding to the wiki's DBname. For example the Latin Wikipedia's siteid is lawiki. Each external page can have only one link registered in Wikidata and one item can only have one link to each external site.
Sitelink (Interlanguage link; in the user interface called List of pages linked to this item) is an identification of a linked page on another site. It consists of a site identifier and a title, and are stored in individual items in Wikidata. They are used both for identifying an item from an external site, and as a central storage of interwiki (interlanguage) links.
Help:Sitelinks
Statement is a piece of data about an item, recorded on the item's page. A statement consists of a claim (a property-value pair such as "Location: Germany", together with optional qualifiers), augmented by optional references (giving the source for the claim) and an optional rank (used to distinguish between several claims containing the same property). Wikidata makes no assumptions about the correctness of statements, but merely collects and reports them with a reference to a source.
Help:Statements
String (also character string) is a general term for a sequence of freely chosen characters interpreted as text (e.g. "Hello") — as opposed to a value interpreted as a numerical value (3.14), a link to an item (e.g. [[Q1234]]) or a more complex datatype (the set {1,3,5,7} ). Wikidata will in addition to a string datatype support language specific texts; "monolingual-text" and "multilingual-text" as the value of a property.
Title is the name of a page. The title is unique per wiki. In Wikidata a title is either an item identifier such as Q42 or it starts with a namespace prefix such as Help:. Titles of pages in other Wikimedia wikis are required to connected these pages to Wikidata items via sitelinks.
Values (also datavalues) are the information pieces embedded in each claim. Depending on their datatype, they can be a single value (like a number) or a value consisting of several parts (like a geographical position with longitude and latitude). The special cases "unknown value" or "no value" can also be selected.

Wikibase 这是维基数据后台的软件。它是由Wikibase、Wikibase client和WikibaseLib三个MediaWiki扩展组成:

    1. The Wikibase extension (for the Wikidata server, often called repository or just repo) allows a dedicated MediaWiki installation to collect and maintain structured data and is used on the Wikidata website.
    2. The Wikibase client extension (often called just client) enables MediaWiki installations such as the Wikipedias to query and display data from a Wikidata server on its own pages, and will be deployed on Wikipedias in different languages, and probably on other sites.
    3. The WikibaseLib extension has common libraries for both of the major extensions.

Wikidata 即“维基数据”。这个Wikimedia项目运行的是一个采用了Wikibase扩展MediaWiki实例。它允许维基数据编者们录入数据和浏览页面
