TemplateData扩展引入了‎<templatedata>标记和API，它们共同允许编辑者指定应如何调用模板。 此信息作为最终用户的格式良好的表提供，并作为JSON API提供，它使其他系统（例如VisualEditor）能够构建用于处理模板及其参数的接口。 有关深入的帮助，请参阅Help:TemplateData 。

安装

• 下载文件，并将其放置在您extensions/文件夹中的TemplateData目录内。
• 将下列代码放置在您的LocalSettings.php 的底部：

  wfLoadExtension( 'TemplateData' );
  

•  完成 – 在您的wiki上导航至Special:Version，以验证已成功安装扩展。

编辑数据

TemplateData扩展会在模板页面的维基文本中定义‎<templatedata>标签（当然也可以是从其他页面嵌入包含的），从而实现效果。 该扩展在设计上是兼容一种很多wiki都有的常见布局的，即嵌入包含一个单独的文档页面（但不是必需的）。 ‎<templatedata>的内容必须是有效的JSON，其格式如下所示，注意所有的描述必须是纯文本（模板数据中不接受维基文本）。

页面包含‎<templatedata>块时，TemplateData会在页面保存时，做出以下检查：

1. 内容必须是有效的JSON；
2. JSON结构中的每一项必须是下文指定的预设类型（例如对象、数组或原始类型）；
3. 对于那些具有指定的可能的值的列表（例如params.yourParameterName.type）的项，JSON对象中的值必须与这些值中的某一种相匹配。

如果这些检查中的任何一项失败，服务器将不允许用户保存，并且将在编辑页面的上方显示错误消息。

对于自动值的像，bug 2700使得subst:无法在任何添加到‎<tag>（包括‎<ref>和‎<gallery>标签）的模板中生效。 TemplateData在这种情况下不会阻止保存，但结果的维基文本在使用模板时仍然不被正确解析。

注意不能使用{{#tag:templatedata}}替代‎<templatedata>。

格式

以下内容是JSON数据的视觉化版本，正如包含在‎<templatedata>‎</templatedata>标签的模板页面定义的。 格式规定可参考TemplateData。 有关最新版本，请参考Specification.md。

TemplateData对象

TemplateData对象是一个“JSON根元素”，包含在模板页面的‎<templatedata>元素中。

键	类型	描述
description	InterfaceText或null	模板的简要说明。 必须为纯文本格式。 如果填写了，当编辑单个模板时以及在用户选择其中的一个时搜索结果中会显示为说明文本。 默认设置为null。
params	包含参数（Param）对象的对象	An object that maps each parameter name of the template to a corresponding Param object describing the properties of that parameter.
paramOrder	Array containing parameter name strings	The logical order in which parameters should be displayed. The array contains each parameter key exactly once. Each string must be a valid key in the params object.
sets	Array containing Set objects	An array containing set specifications. A set is a group of parameters that should be used together. 默认值为[]。 请注意，sets功能仍在开发中。
format	字符串，inline或block	How the template's wikitext representation SHOULD be laid out. 默认设置为inline。 See #Custom_formats for other custom formats.
maps	A Maps object	An object that maps a simplified name of a third party consumer of the template data (i.e. Citoid, Special:MyLanguage/Wikidata, etc.) to an object that in turn maps a name of a consumer parameter to one or more corresponding names of template parameters.

Param object

键	类型	默认	描述
label	InterfaceText	null	参数的（非常）简短的名称。 尽量保持20个字符以下。
description	InterfaceText	null	参数的简短描述，以使用户知道从选项列表中选择哪个。
required	布尔值	false	Whether the parameter is required for the template to work (true if this parameter must be specified).
suggested	布尔值	false	Whether the parameter is suggested for the template to be useful (true if this parameter should be specified).
deprecated	布尔值或字符串	false	Whether the parameter is deprecated. The value can be a string of instructions giving the user guidance what instead can be done, or be simply true.
aliases	Array containing strings	[]	List of aliases. An alias is an alternative name for the parameter that may be used instead of (not in addition to) the primary name. Aliases are not documented in a separate Parameter object. If they need more information, they should be in their own property marked "deprecated".
default	InterfaceText	null	The default value used by the template if no value is assigned to the parameter, or a description thereof.
autovalue	字符串	null	A dynamically-generated default value in wikitext, such as today's date or the editing user's name; this will often involve wikitext substitution, such as {{subst:CURRENTYEAR}}.
example	InterfaceText	null	An example text for the parameter, to help users fill in the proper value.
type	字符串	"unknown"	The type of the parameter, for (soft) type hinting. One of: 字符串值 参数类型 "unknown" Assumed type if not set "number" Any numerical value (without decimal points or thousand separators) "string" Any textual value. May contain line breaks. "line" Short text field – use for names, labels, and other short-form fields. This is supposed to be text that is not expected to contain line breaks. "boolean" A boolean value ('1' for true, '0' for false, '' for unknown), see three-valued logic. "date" A date in ISO 8601 format, e.g. "2014-05-09" or "2014-05-09T16:01:12Z" "url" A URL, including protocol, e.g. "http://www.example.org", "https://example.org", or "//example.org". "wiki-page-name" A valid MediaWiki page name for the current wiki. Doesn't have to exist, but if not, should be a valid page name which could be created. "wiki-file-name" A valid MediaWiki file name for the current wiki. Doesn't have to exist, but if not, should be a valid file name which could be uploaded. Should not include the namespace (e.g. "Foo.svg" not "File:Foo.svg" or "Bild:Foo.svg"). "wiki-template-name" A valid MediaWiki Template name for the current wiki. "wiki-user-name" A valid MediaWiki user name for the current wiki. Doesn't have to exist, but if not, should be a valid user name which could be created. Should not include the namespace (e.g. "Foo" not "User:Foo" or "Usario:Foo"). "content" Page content in wikitext, such as text style, links, images, etc. "unbalanced-wikitext" Raw wikitext that should not be treated as standalone content because it is unbalanced – for example, templates concatenating incomplete wikitext as a bigger whole, such as {{echo|before=<u>|after=</u>}}
inherits	字符串	无 substituted	The name key of another parameter (must be a valid key in the params object). The current Parameter Object will inherit properties from the specified Parameter Object, with local properties overriding the inherited ones.

Set object

键	Object or primitive type	描述
label	InterfaceText	A (very) brief name for the parameter set. Try to keep under 20-ish characters.
params	字符串数组	One or more names of parameters to include in the set (each must be a valid key in the params object). A parameter may be in multiple sets. Not every parameter must be in a set.

Maps object

键	类型	默认	描述
name of consumer	对象	{}	An object that maps a name of a consumer to an object that in turn maps a name of a consumer parameter to one or more corresponding names of template parameters. The names of the template parameters can be specified either as a string (one name), an array of strings (several names), or an array of arrays of strings (several sets of names); each of these strings must be a valid key in the params object elsewhere in the same template's TemplateData. A specific template parameter may be in multiple maps, and it may be used in the values of multiple keys in a given map, but not every template parameter must be in a map. A shortened example from English Wikipedia's Template:Cite_news#TemplateData illustrates the structure of a maps object. { "proveit": { "main": "title", "textarea": [ "quote" ] }, "citoid": { "title": "title", "url": "url", "publisher": "publisher", "publicationTitle": "work", "date": "date", "ISSN": [ "issn" ], "ISBN": [ "isbn" ], "contributor": "others", "author": [ [ "first", "last" ], [ "first2", "last2" ], [ "first9", "last9" ] ], "editor": [ [ "editor-first", "editor-last" ] ] } }

InterfaceText (string or object)

A free-form plain-text string (i.e. no wikitext or HTML) in the content-language of the wiki, or an object containing those strings keyed by language code.

The default value for all InterfaceText fields is null.

字符串类型

If it is a string, it must contain a non-localized string in the content language of the local wiki.

Object type

If it is an object, the object must have this mapping:

键	类型	描述
Wikipedia language code	字符串	Localized string for use on the Wikipedia corresponding to the given language code.

Example of object mapping:

键	值
"en"	"Welcome to Wikipedia"
"de"	"Willkommen bei Wikipedia"
"fr"	"Bienvenue sur Wikipédia"
"nl"	"Welkom op Wikipedia"
"it"	"Benvenuti su Wikipedia"
"es"	"Bienvenidos a Wikipedia"
"ru"	"Добро пожаловать в Википедию"

示例

An example TemplateData structure as specified within wikitext on a template page.

<templatedata>
{
    "description": "Label unsigned comments in a conversation.",
    "params": {
        "user": {
            "label": "User's name",
            "type": "wiki-user-name",
            "required": true,
            "description": "User name of person who forgot to sign their comment.",
            "aliases": ["1"]
        },
        "date": {
            "label": "Date",
            "suggested": true,
            "description": {
                "en": "Timestamp of when the comment was posted, in YYYY-MM-DD format."
            },
            "aliases": ["2"],
            "autovalue": "{{subst:#time:Y-m-d}}"
        },
        "year": {
            "label": "Year",
            "type": "number"
        },
        "month": {
            "label": "Month",
            "inherits": "year"
        },
        "day": {
            "label": "Day",
            "inherits": "year"
        },
        "comment": {
            "required": false
        }
    },
    "sets": [
        {
            "label": "Date",
            "params": ["year", "month", "day"]
        }
    ],
    "maps": {
        "ExampleConsumer": {
            "foo": "user",
            "bar": ["year", "month", "day"],
            "quux": [
                "date",
                ["day", "month"],
                ["month", "year"],
                "year"
            ]
        }
    }
}
</templatedata>

Below is how the above example would be displayed on the template page:

Label unsigned comments in a conversation.

Template parameters

Parameter		Description	Type	Status
User's name	user 1	User name of person who forgot to sign their comment.	User	required
Date	date 2	Timestamp of when the comment was posted, in YYYY-MM-DD format. Auto value {{subst:#time:Y-m-d}}	Unknown	suggested
Year	year	no description	Number	optional
Month	month	no description	Number	optional
Day	day	no description	Number	optional
comment	comment	no description	Unknown	optional

API

See the generated help at Special:ApiHelp/templatedata. A sample invocation (formatted for human readability) is:

api.php?action=templatedata&titles=Template:Cite%20web&format=json [在Api沙盒中尝试]

This returns the template data for Template:Cite web. The ‎<templatedata>...‎</templatedata> block for this template is on its transcluded template documentation page, en:Template:Cite web/doc.

Additions and changes to JSON as received from the API

The JSON structure provided in response to an API HTTP get request is significantly different than that which is defined in the ‎<templatedata>...‎</templatedata> block. In response to the API request, extension TemplateData makes the following changes to the JSON object:

• Adds two wrapping objects:

• 1. An overall Pages Object containing one or more Page Objects
  2. An object with a numeric key: a Page Object

• Additions/changes to the actual TemplateData Object

• 1. Add the title key with the name of the page from which the data was requested (e.g. "Template:Cite web").
  2. 添加sets键
  3. Change all TemplateText occurrences that are just strings to objects with a single key for the current wiki's Wikipedia language code
  4. 删除所有inherits键。
     • Add all properties from parameter from which an inheritance is defined which are not superseded by explicitly defined keys in the inheritor's Parameter Object.
  5. Add default values for all keys in each Parameter Object which have not been explicitly defined or inherited.

Visualised differences in a TemplateData JSON object delivered by the API

Wrapper objects added to JSON delivered by API
These are not defined in the JSON object enclosed by the ‎<templatedata> tags on the template page.

JSON Root 键 类型 描述 pages Page Object The Page object (contains one key which is the page number). If multiple pages were requested at one time there will be multiple Page Objects.

Page Object 键 类型 描述 (页码) TemplateData Object The TemplateData Object containing the information payload. The key is a static page number for the template page from which the JSON data was requested.

TemplateData Object (added by API)
The following key is added to the root of the JSON object which is enclosed in ‎<templatedata> tags on the template page.

键	类型	描述
title	字符串	The page name of the template (e.g. "Template:Cite web"). This key is not contained in the JSON structure on the template page. It is added to the structure by the MediaWiki software in route to delivery via the API.
sets	Array containing Set Objects	An array containing set specifications. A set is a group of parameters that should be used together. If this does not exist on the template page it is added as an empty array to the structure provided by the API.

Parameter Objects from API

键	类型	描述
label	InterfaceText	translated to InterfaceText object, if not already in that format.
required	布尔值	如果未定义，则添加默认值false。
description	InterfaceText 或 null	如果定义为字符串，则转换为InterfaceText对象。 If not defined, key is added with a null value.
deprecated	布尔值或字符串	If not defined, default value of false added.
aliases	字符串数组	If not defined, a default empty array is assigned (i.e. [] ).
default	字符串	如果未定义，则分配默认值""。
type	字符串	如果未定义，则分配默认值"unknown"。
inherits	（已移除）	This key is removed and all inherited keys are added. Keys defined for the current parameter take precedence and any keys not defined on either the current param, or the one from which it inherits are given the default value.

InterfaceText (Object or null):
An object containing strings keyed by language code.

键	Object or primitive type	描述
Object (containing localized strings by Wikipedia language code) If a TemplateData field on the template page contains a string, not an object with localized strings, MediaWiki translates it into an InterfaceText Object with a string assigned to the key name of the source Wikipedia Wikipedia language code. The default for all InterfaceText fields is null.
(Wiki language code)	字符串	Localized string for use on the Wikipedia corresponding to the Wikipedia language code.
