拡張機能 TemplateData でウィキテキスト テンプレートとそのパラメーターの情報を保存すると編集インターフェイスがそれを取得してテンプレート エディターに表示するため、そのテンプレートを使用したページの編集がしやすくなります。

2019年4月より TemplateData はウィキメディアのすべてのウィキに既定の UX (利用者体験) として組み込まれました。アカウントを登録していてもいなくても、参加するユーザーがテンプレートを追加すると適用されます。 既定のソース編集でもビジュアル編集でも、同じ適用法です。 スクリプトやツール、ガジェットなどあらゆるところで活用されます。 自身のウィキで使用したい場合は、Extension:TemplateData をインストールする必要があります。

特定のテンプレートに TemplateData を組み込む手順は、本質的にテンプレートの説明文書のページに JSON の小さなコードブロックを追加します (詳細は下記の説明をご参照ください)。 文字で書くと複雑そうですが、処理は思ったよりも簡単です。 実行する方法は主に2つあり、手動か TemplateData 編集機能を使うかです。後者は 画像的な UI で、TemplateData 拡張機能を組み込んだウィキにある"Edit"/"Edit source" ページに配置してあります。 JSON にはパラメーターの一覧が含まれ、テンプレートの個々のパラメーターの情報と、テンプレート本体の説明を添えてあります。 以下に概要を示します。

個別のテンプレートに TemplateData が設定されると、この情報は利用者がテンプレートを追加するたびユーザーインターフェースに表示され、ときには元の情報と置換され、あるいは既存の情報に追加されます。 場合により、そのせいでエディタの挙動を変化させることもあり、テンプレートの編集や追加の時に気がつきます。 This can make it much easier for users to identify what they need to do with a template when adding it.

歴史

TemplateData was originally developed in early 2013 with VisualEditor in mind, which was in MediaWiki testing stages at the time. VisualEditor はウィキメディアのウィキ群で採用するメインの視覚的な編集インターファースで、TemplateData ではテンプレートの追加をするとき、より利便性の高いエディタとしてこれを容認しています。 VisualEditor では即時に公式にサポートされました。 2013年から2016年にかけてさまざまなウィキメディアのウィキ群で VisualEditor wを既定の機能として導入した結果、TemplateData もその一環となりました。

2016年12月時点で VisualEditor インターフェースはベータ機能として、ソースコード編集に使えるようになりました。 This was termed the 2017 wikitext editor. This brought the features of TemplateData to source editing for the first time.

In March 2018, Sam Wilson developed TemplateWizard , a GUI template editor extension for the default Wikimedia source editor, WikiEditor (otherwise known as the 2010 wikitext editor), designed to make the process of adding templates easier by using information from TemplateData. In April 2019, TemplateWizard was made a default part of the 2010 wikitext editor on all Wikimedia wikis. これはすなわち、現状でウィキメディアのウィキ群における TemplateData は、ビジュアル編集でもソース編集でも規定の部分となったことを意味します。

Adding or editing TemplateData

To add or edit TemplateData, first navigate to a template's page, located at "/Template:Templatename".

Prior checks

There are two things you should check before adding or editing TemplateData, in the following order:

1. whether the template has a documentation subpage

1. whether the template already has TemplateData and whether this is located on the template page or the documentation subpage.

Checking for the documentation subpage

The first thing to do is identify whether the template has a subpage for its documentation or not.

There are two main ways templates on most Wikimedia wikis store their usage notes and other data that shouldn't be included in the actual template itself, like categories the template should be contained in:

• The vast majority use a documentation subpage.

This is a page located at the template's name followed by "/doc". In this case, on the main template page after the template source code, there is only the text "{{Documentation}}" between <noinclude> tags. Here, the {{Documentation}} template transcludes all the /doc page's content onto the template page. This makes the template's source code look much cleaner.

• A small minority keep the information on the template's main page, after its source code.

In this case, it is contained after "{{Documentation|content=", which is between <noinclude> tags.

You can quickly identify whether a template has a /doc page by checking if the " Template documentation" (or similar) heading has links like "[view] [edit] [history] [purge]" after it. This may look slightly different on different wikis. ごくまれには、これらのボタンが表示されて /doc ページが作成済みなのに、メインのテンプレートページに説明文書が残る場合があります。 This will happen if a user has added a custom /doc page title between "{{Documentation|" and "|content=" then added content after "|content=".

A slightly more reliable way to check is by looking for the notice, "The above documentation is transcluded from Template:Templatename/doc" (or similar), in the box at the bottom of the page.

If a template doesn't have a documentation subpage

If a template doesn't have a documentation subpage, you have two options:

• You can either create it and move its documentation (if it has any) there.

After this, you can then add TemplateData to the documentation subpage. This is the preferred option.

• Or, you can add or edit TemplateData on the main template page.

Creating the doc subpage and moving the documentation contents

On most Wikimedia wikis, you can only create a page if you are a registered user (and, at least on the English Wikipedia, have been for more than four days and have made at least ten edits).

To do this, click "Edit"/"Edit source" on the main template page, and look for the <noinclude> tags and their contents, usually at the bottom.

It should look something like this:

<noinclude>
{{Documentation|content=
== Usage ==

Information about usage.

== More example headings ==

More example contents

[[Category:Example category]]
[[Category:Example category 2]]
}}
</noinclude>

It might also have TemplateData already. This will look something like:

<noinclude>
{{Documentation|content=
...
<templatedata>
{
    "description": "",
    "params": {
        "1": {
            "label": "Example parameter",
            "description": "Example parameter description",
            "type": "string"
        }
    }
}
</templatedata>
</noinclude>

Select everything after "|content=" and before "</noinclude>", cut it, then delete "|content=", so you are just left with:

<noinclude>
{{Documentation}}
</noinclude>

Now, save the page.

Next, add "/doc" to the URL in the address bar after the template name, and press Enter. Then, click "Create source".

If your wiki has a {{Documentation subpage}} notice template, add it at the top. You may also want to add some other templates, like a {{Purge button}} or {{Purge}} link, if your wiki has it. 詳細はメタのヘルプをご参照ください。

Beneath this, paste the contents of the clipboard.

Next, enclose the categories within <includeonly> tags. This is so that they don't have an effect on the doc subpage, only on the template's main page.

This will look like this:

<includeonly>
[[Category:Example category]]
[[Category:Example category 2]]
</includeonly>

Some wikis (including the English Wikipedia) have a {{Sandbox other}} template. Use this if the template can be expected to have a sandbox version, located at "Template:Templatename/sandbox". It will stop the categories from having an effect on the sandbox page.

This will look like this:

<includeonly>{{sandbox other||
[[Category:Example category]]
[[Category:Example category 2]]
}}</includeonly>

After this, click "Publish page".

You can now add or edit the TemplateData on the documentation subpage based on the guidance at #Methods.

Adding or editing TemplateData on the main template page

If you do not wish to or are unable to create the /doc page, you can add or edit TemplateData on the main template page. Follow the guidance at #Methods to do this.

If a template has a documentation subpage

If a template has a documentation subpage, you should now check whether it already has TemplateData and whether this is located on the template page or the documentation subpage.

Check both the template page and the /doc subpage for the presence of TemplateData documentation; this looks something like this:

Template parameters

Parameter		Description	Type	Status
Example parameter	1	Example parameter description	String	optional

Alternatively, the TemplateData extension can perform this check for you. Click "Edit" or "Edit source" on either page.

どちらかのページにテンプレートに対応する TemplateData がある場合、ページ上部に黄色の通知が現れ、内容は次のいずれかを表示します。

"Please note: there is already a TemplateData block on the related page "Template:Templatename/doc"", or

"Please note: there is already a TemplateData block on the related page "Template:Templatename""

If the template has TemplateData on its documentation subpage

If the template has TemplateData on its documentation subpage, this is the page you should edit. You can do this by clicking the "[edit]" located after the heading " Template documentation" (or similar), or, if you are already on the /doc page, by clicking "Edit" or "Edit source" at the top. Follow the guidance at #Methods to add or edit the TemplateData.

If the template has TemplateData on its main page

If the template has TemplateData on its main page, you once again have two options:

• You can either move to its documentation subpage. This is the preferred option.

• Or, you can edit it on the main template page.

Moving TemplateData to the documentation subpage

To do this, click "Edit"/"Edit source" on the main template page, and look for the <templatedata> tags, enclosed within <noinclude> tags. It should look something like this:

<noinclude>
{{Documentation}}
<templatedata>
{
    "description": "",
    "params": {
        "1": {
            "label": "Example parameter",
            "description": "Example parameter description",
            "type": "string"
        }
    }
}
</templatedata>
</noinclude>

Cut only the <templatedata> tags and their contents out of the code, then save the page.

Next, edit the documentation subpage by clicking the "[edit]" located after the heading " Template documentation" (or similar).

Type a heading, like "TemplateData", then beneath it paste the TemplateData.

You can now edit the TemplateData based on the guidance at #Methods.

Editing TemplateData on the main template page

If you do not wish to move the TemplateData to the /doc page, you can edit it on the main template page. #Methods節に TemplateData の編集方法を示します。

If the template does not yet have TemplateData but has a doc subpage

If the template does not yet have TemplateData, you should add it to the documentation subpage.

Do this by clicking the "[edit]" located after the heading " Template documentation" (or similar), or, if you are already on the /doc page, by clicking "Edit" or "Edit source" at the top. Type a heading, like "TemplateData", then add it beneath this heading. The section #Methods explains how to add TemplateData.

Methods

TemplateData editor method

This is the simpler way to add or edit TemplateData, possible for inexperienced users.

TemplateData 拡張機能は画像で手順を示す UI を採用し、TemplateData の追加と編集を行います。 It is part of the TemplateData extension. テンプレートデータ編集ツールを使用するには、テンプレートのページ (またはその解説下位ページ) を開き「編集」ボタンまたは「ソースを編集」ボタンを押します。

操作として「編集」「ソース編集」のいずれかを押すと、編集枠のページ名の上部にボタン「テンプレートデータを管理」が現れます。

このボタンをクリックするとTemplateData 編集機能が開きます。 ページに既存のテンプレートデータがある場合、自動的に表示されます。

Features in the above window:

• The top item is "Language". This item allows you to enter text content in multiple different languages, which will show depending on the language setting of the user in Preferences. It will not show depending on the language wiki, as different wikis have entirely different databases of templates. If no language TemplateData exists yet, only the language of the wiki the user is on will be available, but the user can click "Add language" to add more inputs. The language code will show in brackets next to the parameters for which it can be applied to. These include descriptions and labels.

• The next item is the template description. This is the description of the template as a whole and is shown in various places to the user in the template editors while adding a template. This parameter and its effects are outlined here.

• The third item is the wikitext formatting of the template. This parameter determines how the wikitext should be laid out when the user clicks "Insert", the two main types being "inline" (on one line) and "block" (on new lines). This parameter and its effects are outlined here.

If the user chooses "Custom", they will be able to enter a set of wikitext under "Custom format string", according to rules outlined here, to create a custom layout for the template when the user clicks "Insert".

• 第4の項目は「テンプレートのパラメータ」です。これにはパラメータが存在する場合、TemplateData にすでに定義されたものを一覧します。もしテンプレートのソースコードに記述してあるのに TemplateData が未設定の場合、「提示されたパラメータを追加」というボタンが現れます。その提示はテンプレートのソースコードで {{{parametername}}} または {{{parametername|}}} を検知したものを抽出した結果です。「提示されたパラメータを追加」を押すと、それらにソースコードに定義された名称を命名して追加します。またページ上部に緑色の通知が現れます。「2件の新しいパラメータをインポート：パラメータ名」。

• At the bottom is "Add parameter". This allows you to add a parameter manually with a custom name.

The next stage is clicking any one of the parameters in the list. This will allow you to edit that parameter's info.

All of these features and their effects are outlined at #Within a parameter's name.

• TemplateData 編集機能は利用者による「Name」パラメータの白紙化を許可しません。name 文字列を白紙にして TemplateData パラメータを記述したい場合にも、2010年版ウィキ文エディタで TemplateWizard を有効にしてあると問題は起きませんでしたが、VisualEditor あるいは 2017年版ウィキ文エディタではまったく表示されません。TemplateData エディタにおいてこのらんは、唯一、記入が強制されます。

• Clicking "Remove parameter information" will delete the parameter and all its information from the TemplateData. You will not be able to retrieve or undo this in the TemplateData unless you click "X" afterwards. You can undo any changes made after clicking "Apply" by hitting Ctrl+Z.

• Exiting the TemplateData editor after making changes shows a prompt asking if you're sure you want to discard your changes.

When you are finished, click "Apply". This will automatically insert the TemplateData at the bottom of the page before the </noinclude> tag; or, if it already exists, it will update it with the new information without changing its position at all. The TemplateData text will also be selected when you click "Apply".

The TemplateData editor creates a "paramOrder" parameter at the bottom of the TemplateData or updates it if it already exists. これには TemplateData エディタに表示される順序にしたがい TemplateData パラメータを並べてあります。

You can change the paramOrder by dragging the parameters in different orders in the TemplateData editor using the three horizontal bars on the left. "paramOrder" and its effects are outlined here.

After this, click "Save" to save the revision of the page.

Manual method

The alternative is to add or edit TemplateData manually. You may need or wish to do this in some cases. テンプレートデータの構造は JSON 標準に基づいているものの、利用者は JSON がわからなくても TemplateData を配置できます。 It follows a few very simple rules and takes only a few dozen possible predefined parameters and values, almost always in a "parameter": "value" format.

Adding TemplateData manually

Preconsiderations:

• テンプレートの説明文書サブページにTemplateData を記入する場合、当該ページのどこに配置してもかまいません。ご利用の言語版で通例となる配置場所がないかどうかご確認ください。たとえばウィキペディア英語版だと、TemplateData の配置は通常、説明文書ページの最下部です。ドイツ語版ならページ最上部です。
• テンプレートのメインページに TemplateData を追加する場合 (処理は避けるべき理由は#Prior checksをご参照)、きちんと <noinclude>...</noinclude> タグで囲んだかどうか十分に留意する必要があります。

First, click "Edit" or "Edit source" on the respective page, then go to the position you are adding the TemplateData and write a heading like "TemplateData".

Many wikis (but not all) have a {{TemplateData header}} template, which adds a short notice about the TemplateData. If yours does, add this after the heading.

To start adding the TemplateData, type an opening and closing <templatedata> tag and a pair of curly brackets on new lines, with an empty line between them:

<templatedata>
{

}
</templatedata>

次に、空行に弓カッコ2個を書き、インデントを挟みこんでからパラメータの記述をはじめます。パラメータごとの詳細は#TemplateData parametersの節をご参照ください。ほとんどはオプションですが、中には強く推奨されるものもあります。

Parameters can be in any order, but the order that will best correlate with what shows in the TemplateData documentation and contribute to ease of use for editors is the following:

<templatedata>
{
    "description": "",
    "format": "",
    "params": {
        "parameter1": {
            "aliases": ["",""]
            "label": "",
            "description": "",
            "type": ""
        }
    },
    "paramOrder": [
    	""
    ]
}
</templatedata>

またパラメータの順序は、たとえば#Unexpected propertyオブジェクトがオブジェクト内に置かれたか確認し、エラーがあると保存時に「予期しないプロパティ」というメッセージが表示されます。

例

Here is some example TemplateData for a hypothetical cleanup template. The template would display a notice, and its source code would be programmed to place the page into a dated category based on the month and year entered. The notice could also contain a link to a talk page section, if specified. The TemplateData would look something like this:

<templatedata>
{
	"description": "Use this template to indicate that an article is in need of cleanup.",
	"format": "inline",
	"params": {
		"date": {
			"label": "Month and year",
			"description": "The month and year that the template was added",
			"type": "string",
			"autovalue": "{{SUBST:CURRENTMONTHNAME}} {{SUBST:CURRENTYEAR}}",
			"example": "January 2013",
			"suggested": true
		},
		"reason": {
			"aliases": ["1"],
			"label": "Reason",
			"description": "The reason the article is in need of cleanup",
			"type": "string"
		},
		"talk": {
			"aliases": ["talksection"],
			"label": "Talk page section",
			"description": "The section of the talk page containing relevant discussion",
			"type": "string"
		}
	},
	"paramOrder": [
		"date",
		"reason",
        "talk"
	]
}
</templatedata>

The corresponding TemplateData documentation would display as the following:

Use this template to indicate that an article is in need of cleanup.

Template parameters

This template prefers inline formatting of parameters.

Parameter		Description	Type	Status
Month and year	date	The month and year that the template was added Example January 2013 Auto value {{SUBST:CURRENTMONTHNAME}} {{SUBST:CURRENTYEAR}}	String	suggested
Reason	reason 1	The reason the article is in need of cleanup	String	optional
Talk page section	talk talksection	The section of the talk page containing relevant discussion	String	optional

TemplateDataのパラメーター

Each parameter for TemplateData is listed below with a description and example. They are also listed at Extension:TemplateData#Format.

• この情報は2020年2月時点で現状に即しており、パラメータの新規追加あるいはテンプレート編集インターフェイスの更新により、既存のパラメータを維持したり、特定のパラメータの扱い方が変わったりします。
• ウィキ マークアップは解説やラベルでは動作しません。 平文のみの文字列しか受け付けません。
• New lines ("\n") in descriptions, labels, examples or defaults will not show in any of the main editors (TemplateWizard, VisualEditor or the 2017 wikitext editor), even though they show in the auto-generated TemplateData documentation. They are replaced by a null string in input forms and by a space elsewhere.

パラメーター	説明	例
description	"description"パラメータはテンプレートの役割を説明します。 オプション、ただし強く推奨されます。 Effects On the template documentation page, the description will show in plain text below the "Template data for [template name]" subheading. In all main editors (VisualEditor , the 2017年版ウィキテキストエディター and the 2010 wikitext editor with TemplateWizard), the description shows in two main instances: below the template name in each search suggestion when the user is searching for a template テンプレート編集機能のテンプレート名の下にあり、テンプレートのパラメータに値を付与します。 VisualEditor および2017年版ウィキ文エディタでは、検索候補ごとに説明文をおよそ半角50文字前後に短縮して表示して「...」を添えますが、テンプレートの編集ウィンドウでは解説文書の全文を示します。 Both are shown in grey text. In the 2010 wikitext editor with TemplateWizard, the whole description shows under each search suggestion, in grey text. In the main template editor window, descriptions longer than four lines (about 540 characters) are provided a separate scrollbar, and they are shown in black text. If not specified If the description parameter does not exist or is not specified, the text "No description." will be displayed in the TemplateData documentation below the "Template data for [template name]" subheading. Additionally: これは VisualEditor および2017年版ウィキ文エディタでは、まるで TemplateData のないテンプレートと同様の挙動をし、説明文書ではなく以下の文字列を表示します。 "The "Template:Templatename" template doesn't yet have a description, but there might be some information on the template's page." in the 2010 wikitext editor with TemplateWizard, the following text will display where the description would be (though not in search suggestions): "No description exists for this template." This is different to the two standard placeholder descriptions when TemplateData doesn't exist: "Due to missing TemplateData, parameters for this template have been auto-generated. Please be aware that they may not be accurate." "No parameters could be determined for this template due to absence of TemplateData documentation. You may insert the template without parameters."	"description": "これはテンプレートについてコモンズカテゴリにリンクするためのテンプレートです。",
format	その次にあるのが "format"です。このテンプレートがウィキテキストの中でどのようなレイアウトで表示されるべきかを説明します。 これには選択肢があり、"inline" と "block" の標準設定にするか、利用者がカスタム書式をウィキテキスト形式のシンボルで書くか選べます。シンボルと例文など、詳細は#Custom formats節をご参照ください。 This parameter is not required, but it is recommended. The default behaviour when this parameter does not exist is inline formatting, and no corresponding notice is displayed in the TemplateData documentation below the table heading. Effects Inline: パラメータを "inline" に設定すると、テンプレートによって個人設定に対応する通知を TemplateData 説明文書に表示します。表示位置は表のヘッダ「テンプレートのパラメータ」の直下で、次のような表現が作成されます。 "[circles and pipes icon] This template prefers inline formatting of parameters." When inserted, the template will lay its wikitext out on a single line with no white space between elements, like so: {{Foo|bar=baz|qux=quux}} Block: パラメータを "block" に設定すると TemplateData 説明文書に、テンプレートによって次のような表現が作成されます。 "[stacked blocks and pipes icon] This template prefers block formatting of parameters." When inserted, the template will distribute its parameters each on a new line, with single spaces between each element, like so: {{Foo | bar = baz | qux = quux }} Custom formatting: Alternatively, if the parameter is set to a custom string of wikitext, as per the rules listed at #Custom formats, the template will display the following preference notice in its TemplateData documentation: "[cogwheel icon] This template has custom formatting." When inserted, the template will lay its wikitext out as per the given wikitext.	"format": "inline"
params	The "params" object contains the information for each parameter of the template. It is required, and its parameters can be viewed in the #Within params section. It should contain the name of each parameter followed by a set of TemplateData sub-parameters listed in #Within a parameter's name. 複数のパラメータがある場合は、閉じる波カッコごとに半角カンマ「,」で区切って 並べます (最後の閉じる波カッコ1ヵ所だけ区切っても正しく動作しません。)	"params": { "parameter1": { ... // パラメーター情報 }, // このカンマを見落とさないこと "parameter2": { ... // parameter info }, // こちらにもあります: "parameter3": { ... // パラメーター情報 } // but not here }
paramOrder	"paramOrder" オブジェクトはオプションとしてテンプレートエディタに加えると、テンプレートのパラメータの表示順序を規定します。 How to use It is used by adding the parameter "paramOrder", followed by a colon, a space and an open square bracket, then typing the name of each of the template's parameters in speech marks in a desired order, separated by commas. Finally, end it with a closed square bracket. This creates an array. The parameters do not have to be on new lines (they can be "paramOrder": ["param1","param2","param3"]), but placing them on new lines may aid in legibility. It is recommended that you place "paramOrder" after "params", like how the TemplateData editor does, because it does not show in the TemplateData documentation but simply forces the order of the parameters. Someone might want to quickly look at the parameter details and edit them rather than scroll past the "paramOrder", especially if there are a lot of parameters. If you do choose to place it somewhere other than the end of the TemplateData, make sure it has a comma at the end. Every parameter mentioned in the TemplateData must be included, otherwise a "Required property" error will show. If not specified If "paramOrder" does not exist or is not specified, the template's parameters will display in the order they are declared in the template's source code. If the source code contains objects inside objects, parameters in outer objects will come first, followed by inner objects. With other parameters 2010年版ウィキ文エディタで TemplateWizard を有効にした場合、"paramOrder"とは無関係に "required" パラメータが常にページ上部に表示され、"suggested" パラメータは常に2番目、その下に"optional"類を配置します ("deprecated" パラメータはこの版のエディタでは非表示です。詳細は "deprecated" をご参照ください。) "paramOrder" will only enforce its order within these categories (i.e., all "required" parameters will be in the order specified by "paramOrder", and all "suggested" parameters will be too, but all "suggested" parameters will appear below all "required" parameters). "paramOrder"は VisualEditor および2017年版ウィキ文エディタではパラメータの状況に無関係に順序を強制的に配置します。	"paramOrder": [ "date", "reason", "talk" ]

Within params

パラメーター	説明	例
parameter name	params オブジェクトの最上位レベルの項目のみ、テンプレートのパラメータ名に採用されます。 たとえばテンプレートのソースコード内に {{{date}}} がある場合、これを"date"と命名して "params" の配下に置きます。 表示されるパラメータの名称が {{{1}}} その他の数字の場合があります (そららの TemplateData 名はたとえば "1" となります。) These parameters behave in such a way that, when a user inserts a template, they can omit their name and the equals sign (i.e., |value| instead of |parametername=value|). Their number indicates which unnamed parameter they are when multiple unnamed parameters are used. For example, expect that in {{example template|value1|value2}} value1 is the value of parameter {{{1}}}, and value2 is the value of parameter {{{2}}}. その方向に合わせて TemplateData のパラメーターをきちんと解説してください。 Note: a user can still force the use of {{{2}}} without {{{1}}} by inserting a parameter named "2" in the template editor or typing "|2=" in wikitext. How to use これらの "parameter name" オブジェクトには個別にパラメータの情報一式を書く必要があり、形式はさらに TemplateData パラメータで表現します。 These are listed in the following section, Within a parameter's name.	"1": { // パラメータの名前 ... // パラメータに関する情報はここに。 }

Within a parameter's name

Parameter	説明	例
aliases	"aliases" パラメータはオプションの項目で、特定のテンプレートに複数の名称があるとき使います。 You can check this by going into the template's source code and looking for: {{{parameter1|{{{parameter2}}}}}}, or {{{parameter1|{{{parameter2|}}}}}} This means that if the user inserts either of these parameters with a value, they will perform the same function. Literally, it translates to, "Value of parameter1. If parameter1 doesn't exist or have a value, value of parameter2." In the second case, it also means, "If parameter2 doesn't exist or have a value, no value." To insert the "aliases" parameter, add the text "aliases" followed by a colon, a space and an open square bracket, then typing the name of each of the parameter's aliases in speech marks, separated by commas. Finally, end it with a closed square bracket. This creates an array.	"aliases": ["1", "talk", "talksection"],
inherits	"inherits" is an optional parameter for when a parameter should inherit all of the TemplateData of another parameter. This can then be overridden by any parameters specified for the inheriting parameter. To use this parameter, type "inherits" : followed by another template parameter's name, such as "talk" or "1". You can then type another specific setting for the parameter underneath if you wish, like "label" : "A different label". The first parameter will inherit all of the second parameter's properties except this one.	"params": { "トピック1": { "label": "トピック", "description": "曖昧さ回避ページにあげたトピック", "type": "string" }, "トピック2": { "inherits": "トピック1" }, "トピック3": { "inherits": "トピック1", "label" : "A different label" } }
label	次の"label"に人間が読めるパラメータのタイトルを指定すると、テンプレート編集ツール内に表示します。 It displays this in place of the parameter's raw name. このパラメータはオプション、ただし強く推奨されます。	"label": "Month and year",
description	ここで言う "description" の箇所とはテンプレート全体の説明ではなく、パラメータの説明です。 This description is shown in a tooltip when the user hovers over the "i" symbol next to the parameter in the template editor. オプション、ただし強く推奨されます。	"description": "The month and year that the template was inserted",
type	See the #Type parameter section.
default	Occasionally, a template parameter is programmed to have a default value that is used unless you change it. The "default" item is an optional item intended to tell the user what this value is. The value does not have to match the actual default and has no functional effect. 既定値がない場合はこのパラメーターを無視することが出来ます。 Effects 主要なエディタすべて (VisualEditor、2017年版ウィキ文エディタならびに2010年版のウィキ文エディタで TemplateWizard を有効にした場合) では、編集対象のパラメータの設定値が空の場合、入力ボックス内に「既定」の文字列をグレーに反転表示し、その書式は"Default: default text"です。 Additionally, it will show in plain black text in the parameter description (when the user hovers over the "i" symbol). これは VisualEditor および2017年版ウィキ文エディタの場合は指定により、パラメータの説明の下部で「欄の記入は 必須もしくは「欄は非推奨」の直下 (2010年版ウィキ文エディタでは非表示) で「例」がある場合はその上に配置します (2010年版ウィキ文エディタのパラメータ解説では「例」は非表示。) In the 2010 wikitext editor with TemplateWizard, the "default" text shows directly after the parameter description, on the same line, following a space. It shows in the same format as the other editors ("Default: default text"). With other parameters In all main editors (VisualEditor, 2017 wikitext editor and the 2010 wikitext editor with TemplateWizard), if "default" is specified, the "example" value will not show in the input box.	"default": "Category:CommonsRoot",
autovalue	パラメータには "autovalue" つまり自動値を設定できます。利用者がそのようなテンプレートをページに用いる場合、自動値が自動的にインプット欄に表示されます。例えばクリーンアップ用テンプレートの多くには日付の記入が必須で、日付パラメータの自動値をあらかじめ{{subst:CURRENTMONTHNAME}} {{subst:CURRENTYEAR}}に設定しておくと、日付にテンプレートを追加した月・年の値を自動で付与できます。 This parameter does not force the value to always be this value. The user can freely change the value that is automatically inputted into the parameter in the template editor. With other parameters In all main editors (VisualEditor, 2017 wikitext editor and the 2010 wikitext editor with TemplateWizard), "autovalue" overrides the visible effects of "url" in VisualEditor and the 2017 wikitext editor. 詳細は"type"の説明文書をご参照ください。	"autovalue": "{{subst:CURRENTMONTHNAME}} {{subst:CURRENTYEAR}}"
example	"example" 値はオプションで、目的はパラメータの使われ方を示すため、入力例を表示します。 Effects In all main editors (VisualEditor, 2017 wikitext editor and the 2010 wikitext editor with TemplateWizard), it shows a grey text in the input box of any open parameter when it is empty, in the format "e.g. example text". Additionally, in VisualEditor and the 2017 wikitext editor, it shows the same text in black, non-italic font below the parameter description (and below the "default" text, if specified). With other parameters In all main editors (VisualEditor, 2017 wikitext editor and the 2010 wikitext editor with TemplateWizard), "example" will not show in the input box if "default" is specified.	"example": "January 2013",
required	続いて "required" があります。true か false のどちらか一方を設定できます。 指定しなければ、false とみなされます。 これは、単にこのパラメータの記入が必須かどうかを指定します。 Effects この状況は VisualEditor および 2017年版ウィキテキストエディター にいくつかの影響を与えます。 it makes the parameter automatically show up when a user inserts a template; it shows a grey asterisk next to the parameter label; it shows a black asterisk within the input box, on the right; it shows the grey, italic text "Field is required" below the parameter description; it makes the input box glow red if the user clicks away without entering a value; if a user attempts to insert the template without a value in the required parameter, it will show them a prompt, asking if they are sure. If they confirm, it will insert the parameter with a blank value. It will not stop them from inserting the template, though, and it does not result in a visible error by itself (though templates can be programmed to display an error when a required parameter is not filled in). In the 2010 wikitext editor with TemplateWizard, like in the other editors, it causes the parameter to automatically show up when a user inserts a template, but in this editor the parameter cannot be removed. It also does not display "Field is required" in the parameter description; rather, it lists the parameter on the side under "Required parameters". Other than this, it generally behaves the same as in the other editors, except that the prompt says that the input doesn't "match the expected format". With other parameters In VisualEditor and the 2017 wikitext editor, the "deprecated" status does not override the functionality of this parameter, but in the 2010 wikitext editor with TemplateWizard it does. 詳細は非推奨「deprecated」の説明文書をご参照ください。	"required": true
suggested	続いて "suggested" は、true か false のどちらか一方を設定します。 指定しなければ、false とみなされます。 これはテンプレートの利用に際して当該パラメータが「必須」ではないものの強く推奨される（が強制ではない）状態です。 Effects In VisualEditor and the 2017年版ウィキテキストエディター , it causes the parameter to automatically show up when a user inserts a template. If the parameter has an autovalue set, this will also automatically be in the parameter's input box. It has no other effect and doesn't show any additional text or warnings. In the 2010 wikitext editor with TemplateWizard, it does not place the parameter in the template automatically but instead causes it to be listed on the side under "Suggested parameters". The user can then click a "+" next to the parameter to add it to the template. With other parameters 主要なエディタすべてで、この状況の機能性よりも「必須」が優先されます (VisualEditor、2010年版および2017年版ウィキ文エディタ。) It also overrides the displayed "suggested" status in TemplateData documentation (it will display "required" if both "required" and "suggested" are set to true).	"suggested": true
deprecated	最後の、"deprecated" は true か false、または代わりにすべきことの説明を設定します。 指定しなければ、false とみなされます。 これはパラメータの使用が既に推奨されないものの、いまだに存在していることを示すものです。 この現象は、テンプレートを使用は するパラメータの組み合わせが変更された場合に起こりえます。 Effects The effect of this parameter in VisualEditor and the 2017 wikitext editor is that a grey exclamation mark shows next to the parameter's label when it is inserted, and in the parameter's information tooltip, the grey, italic text "Field is deprecated" is shown below the parameter description. It does not affect the functionality or usability of the parameter or show any additional warnings. 文字列を入れるという現実に対し、2020年1月時点で主要なエディタのどれも (VisualEditor、2010年版もしくは2017年版ウィキ文エディタ) 利用者に対して文字列の内容を表示しません。 Inputting a string has the same effect as true. 2010年版ウィキ文エディタで TemplateWizard を有効にした場合でも、この値を true に設定してもパラメータの追加あるいは表示はできません。 With other parameters これと「必須」の両方を true に設定すると、TemplateData 説明文書のパラメータの状況は「非推奨」となるものの、VisualEditor および 2017年版ウィキ文エディタでは両方の機能とも有効に保たれます。利用者がテンプレートを挿入するとパラメータが自動で表示されますが、「非推奨」の警告を伴います。 If you set both this and "required" as true, the parameter status will show as "deprecated" in the TemplateData documentation, but in VisualEditor and the 2017 wikitext editor it will have the same functionality as only "required"; the parameter will automatically show up when a user inserts a template, and it will have the "required" warnings around it. This is the same for if you set "deprecated", "suggested" and "required" as true. In the 2010 wikitext editor with TemplateWizard, "deprecated" overrides the parameters "required" and "suggested".	"deprecated": "代わりに'publicationDate'を使用してください。"
suggested values	The parameter property suggestedvalues lets you define a list of parameter values to be shown to VisualEditor users in a dropdown for easy selection. This can be done either directly in JSON or using the TemplateData editor (no coding required). You can add suggested values to be displayed in the VisualEditor for parameters which have their type set to one of the following options: content line string number unknown unbalanced wikitext. Other types (file, page, template, user, date, boolean, URL) are not currently supported because they have special functionalities in the VisualEditor already, such as autocomplete, which would interfere with the drop-down menu for suggested values in the VisualEditor. Editing TemplateData as JSON in wikitext To add suggested values to any parameter type, add the new property "suggestedvalues" to the parameter in JSON. The “suggestedvalues” attribute must be a list of strings. Editing TemplateData with the TemplateData Editor Click on "Manage TemplateData". Click on the name of the parameter you want to add suggested values to. If it’s not already done, set parameter type to one of the following: content, line, string, number, unknown or unbalanced wikitext. A new input field "Suggested values" will appear. If the parameter is already set to one of these types, the input field should already be visible. Type in the suggested value(s), including any spaces and special characters, and press enter to add the value(s) to the list. Effects Once the values have been added to TemplateData, the VisualEditor will display them in a combo box (a dropdown into which users can also enter a custom value) for the parameter types listed above. The user selects the desired value by clicking on it. If the list of values is long -- for example, a list of a country’s states -- the user can begin typing in the field, whereupon the list will be filtered to show only values containing the typed text. To change an entered value, the user must simply clear the field, and the full dropdown list will appear again. If the user needs a value not included in the list (for example, "message in a bottle") they can type it in manually.	"suggestedvalues": [ "Journal", "Book", "Newspaper", "Magazine" ]

Note: if neither "required", "suggested" nor "deprecated" are set as true for a parameter, its status will show as "optional" in the TemplateData documentation.

Type parameter

そのあとは"type"パラメータの役割は、テンプレートエディタに、そのパラメータ値の解釈を伝えることです。 In some cases, template editors have been programmed to modify the user interface for a certain parameter according to this TemplateData value, such as to only allow the user to enter valid values that match the specified type. このパラメータには、テンプレートのパラメータもしくはその設定値に影響する機能はありません。テンプレート編集者が編集モードでどう表示するか、パラメータをどう扱うか指定するのみです。

How to use

It is used by adding the "type" parameter, followed by a colon and a space, then adding any of the values listed in the table below in speech marks.

Example:

"type": "string",

Effects

2020年2月時点でTemplateWizard が全13件の変数種別のうち8件を表示したのに対し、VisualEditor および2017年版ウィキ文エディタは5種のみでした。

The effects of certain values are likely to change as the template editors get updates to support them. One such effort for VisualEditor and the 2017 wikitext editor is tracked in the Phabricator task T55613. A similar effort to get TemplateWizard to support the boolean value is tracked in T200664.

The currently known effects are listed as follows.

Value	Description
unknown	The "unknown" value is the default type value if no type is set. It can also be set manually, by typing "type": "unknown". Effects In all main editors (VisualEditor, 2017 wikitext editor and the 2010 wikitext editor with TemplateWizard), "unknown" has no visible effects compared to a template without TemplateData.
number	The "number" value is intended for numerical values, including negative values and decimals. Effects In VisualEditor and the 2017 wikitext editor, "number" has no visible effect. In the 2010 wikitext editor with TemplateWizard, "number" causes the input box to display a "+" and "-" button on either side, which can raise or lower a number value in the input box, and the user can only type numbers into the box. The buttons can also lower the number into negatives. With other parameters In the 2010 wikitext editor with TemplateWizard, "number" overrides the effects of "autovalue"; the value of "autovalue" will not be automatically placed in the input box if the parameter type is "number".
string	The "string" value is intended for any string of plain text. Effects In all main editors (VisualEditor, 2017 wikitext editor and the 2010 wikitext editor with TemplateWizard), "string" has no visible effect compared to "unknown".
line	The "line" value is intended for content that should be forced to stay on one line. Effects In VisualEditor and the 2017 wikitext editor, "line" prevents a parameter's input box from allowing new lines, which are usually possible in these editors. In the 2010 wikitext editor with TemplateWizard, "line" has no visible effect (input boxes do not allow new lines by default in this editor).
boolean	The "boolean" value is intended for a value that is either true, false or unknown. This is intended by the manual to be represented by a "1", "0" or blank value. Effects As of February 2020, none of the main Wikimedia editors (VisualEditor, 2017 wikitext editor or the 2010 wikitext editor with TemplateWizard) make use of this value. It has no visible effects. With the autovalue:0 checkbox appears in the VisualEditor, which can be switched on and off.
date	The "date" value is intended for a date in the YYYY-MM-DD (ISO 8601) format; for example, 2014-05-22. The TemplateData manual also designates it as being intended for ISO 8601 date–time combinations, such as 2014-05-22T16:01:12Z", but in practice no major editing interface as of February 2020 uses it in this fashion, and almost all major Wikimedia template parameters take dates and times separately. Effects In VisualEditor and the 2017 wikitext editor, "date" has no visible effect. In the 2010 wikitext editor with TemplateWizard, "date" makes the parameter input box about a third shorter and adds a dropdown calendar, allowing the user to choose a date input. It also displays the grey example text in the input box "YYYY-MM-DD". If an input does not conform to this standard, the box glows red, however the editor will always output a date conforming to the standard (if numbers are entered) or nothing (if only text or nothing is entered). With other parameters In the 2010 wikitext editor with TemplateWizard, "date" overrides the effects of "autovalue"; the value of "autovalue" will not be automatically placed in the input box if the parameter type is "date".
url	The "url" value is intended for a URL, with Internet protocol (e.g., "https://" or "//") included. Effects In VisualEditor and the 2017 wikitext editor, "url" makes the input box display an external link icon (a square with arrow pointing out of it) in the left hand side of the box and makes the box glow red when the user clicks away without entering a URL value that includes a valid Internet protocol (e.g., "https://", "ftp://" or "//") followed by some text. This second effect is similar to that of the "required" setting, but it does not warn the user if they attempt to insert the template without a valid URL. It also occurs with any status setting (such as "suggested"" or "deprecated"). In the 2010 wikitext editor with TemplateWizard, "url" has no visible effect. With other parameters In VisualEditor and the 2017 wikitext editor, "autovalue" overrides the visible effects of "url": when both are set, the input box will not contain a URL icon nor glow red when the user clicks away without entering a valid URL.
wiki-page-name	The "wiki-page-name" value is intended for a page name on a wiki. Effects In all main editors (VisualEditor, 2017 wikitext editor and the 2010 wikitext editor with TemplateWizard), "wiki-page-name" makes the parameter input box show a suggestion dropdown menu containing a list of pages on the wiki, such as articles on Wikipedia, which can be selected. Namespaces can also be defined in the search. Additionally, in VisualEditor and the 2017 wikitext editor, it forces the input box content to stay on one line. It has no other visible effect and doesn't prevent a non-page from being inputted.
wiki-file-name	The "wiki-file-name" value is intended for a file name hosted either locally on a wiki or on Wikimedia Commons. Effects In VisualEditor and the 2017 wikitext editor, "wiki-file-name" has no visible effect. In the 2010 wikitext editor with TemplateWizard, "wiki-file-name" makes the parameter input box show a suggestion dropdown menu containing a list of files hosted both locally and on Wikimedia Commons, which can be selected. The file names do not contain the "File:" namespace prefix. The dropdown menu also shows the thumbnail of the files. It has no other visible effect and doesn't prevent a non-file from being inputted.
wiki-template-name	The "wiki-template-name" value is intended for the name of a template. Effects In all main editors (VisualEditor, 2017 wikitext editor and the 2010 wikitext editor with TemplateWizard), "wiki-template-name" makes the parameter input box show a suggestion dropdown menu containing a list of templates, which can be selected. Additionally, in VisualEditor and the 2017 wikitext editor, it forces the input box content to stay on one line. It has no other visible effect and doesn't prevent a non-template from being inputted.
wiki-user-name	The "wiki-user-name" value is intended for a username on a wiki. Effects In all main editors (VisualEditor, 2017 wikitext editor and the 2010 wikitext editor with TemplateWizard), "wiki-user-name" makes the parameter input box show a suggestion dropdown menu containing a list of actual users' names, which can be selected. Additionally, in VisualEditor and the 2017 wikitext editor, it forces the input box content to stay on one line. It has no other visible effect and doesn't prevent a non-username from being inputted.
content	The "content" value is intended for wikitext of page content, for example, links, images or text formatting. Effects In VisualEditor and the 2017 wikitext editor, "content" has no visible effect. In the 2010 wikitext editor with TemplateWizard, "content" makes the parameter input box one line taller and allows new lines, which regular input boxes in the 2010 wikitext editor do not.
unbalanced-wikitext	The "unbalanced-wikitext" value is intended for wikitext that cannot stand alone, i.e. it lacks an opening or closing tag or refers to other parts of wikitext. Effects In VisualEditor and the 2017 wikitext editor, "unbalanced-wikitext" has no visible effect. In the 2010 wikitext editor with TemplateWizard, "unbalanced-wikitext" makes the parameter input box one line taller and allows new lines, which regular input boxes in the 2010 wikitext editor do not.

特別な書式

When editing the "format" value, you create custom formats by inputting a set of wikitext symbols using some predefined rules.

• {{ - start of the template
• _ - content (e.g., string, integer or parameter). This underscore serves to indicate the minimum length of a value in characters and can be repeated, like _______. If this length is not reached, it fills the remaining characters with spaces. This can be used to align all equals signs to a specific position after a parameter (if used with \n for new lines).
• | - pipe (separates parameters)
• = - equals sign (precedes the value of a parameter)
• \n or pressing the enter key - new line (this will display as ↵ in the entry field)
• - space (can be used with \n to indent new lines)
• }} - end of the template

The wikitext should at least meet the minimum of {{_|_=_}}, otherwise there will be an invalid format string error.

エラー

Syntax error in JSON / Bad JSON format

This error occurs if you attempt to save TemplateData that has certain types of invalid JSON code, such as duplicate keys (parameters) or trailing/missing commas, in VisualEditor or the 2017 wikitext editor (JavaScript-based editors).

"Syntax error in JSON" shows if you attempt to save such code in VisualEditor or the 2017 wikitext editor, while "Bad JSON format" shows if you attempt to open up such code in the TemplateData GUI editor, on template pages.

This error can come up quite frequently while editing a template's TemplateData. The most common mistakes that cause this error include excess commas (such as trailing commas), missing commas and missing quotation marks.

Examples of trailing commas:

<templatedata>
{
    "description": "",
    "format": "inline",
    "params": {
        "1": {
            "label": "",
            "description": "",
            "type": "", // <-- This comma shouldn't be here.
        }, // <-- This comma shouldn't be here.
    }, // <-- This comma shouldn't be here.
}
</templatedata>

Examples of missing commas:

<templatedata>
{
    "description": "",
    "format": "inline" // <-- A comma should be here.
    "params": {
        "1": {
            "label": "",
            "description": "" // <-- A comma should be here.
            "type": ""
        }
    }
}
</templatedata>

Example of missing quotation marks:

"description": An example description // <-- This text should have quotation marks.

To fix these errors, you can either look for the errors in the code yourself, or you can enter the JSON block into an external JSON validator, such as JSONLint, and it will highlight the problematic commas and keys that should be removed.

Due to a longstanding bug, users using the 2010 wikitext editor are able to save pages that have such invalid JSON (details: タスク T128029), as the JavaScript parser is less strict and allows invalid JSON.

Required property "paramOrder(number)" not found.

This error occurs if you state a parameter in "params" that is not stated in "paramOrder". The number in the square brackets refers to the parameter in "paramOrder" that is missing. It refers to its order in the sequence, but it is one less than its actual position, since "paramOrder" is an array; 0 is the first one, 1 is the second, etc.

"params": {
    "date": { ...
    },
    "reason": { ...
    },
    "talk": { ... // <-- This parameter is not stated in "paramOrder", but it should be.
    }
},
"paramOrder": [
	"date",
	"reason"
]

// Error: Required property "paramOrder[2]" not found.

To fix this, make sure all parameters stated in "params" are listed in "paramOrder". Alternatively, you can remove the "paramOrder" object to remove this error.

Invalid value for property "paramOrder(number)".

This error occurs if you state a parameter in "paramOrder" that is not stated in "params". The number in the square brackets refers to the parameter in "paramOrder" that shouldn't be there. It refers to its order in the sequence, but it is one less than its actual position, since "paramOrder" is an array; 0 is the first one, 1 is the second, etc.

"params": {
    "date": { ...
    },
    "talk": { ...
    }
},
"paramOrder": [
	"date",
	"reason", // <-- This parameter is not stated in "params", but it should be.
    "talk"
]

// Error: Invalid value for property "paramOrder[1]".

To fix this, make sure all parameters stated in "paramOrder" are listed in "params". Alternatively, you can remove the "paramOrder" object to remove this error.

Property "params.parametername.required" is expected to be of type "boolean".

This error occurs if you put quotation marks around the value of either "required" or "suggested".

"suggested": "true" // <-- These quotation marks shouldn't be here.

These are boolean values, not strings, therefore they require no quotation marks. To fix this, remove any quotation marks around the values true or false for these parameters.

Property "format" is expected to be ...

もし "format" パラメータは存在するが設定値が "inline" または "block" 以外、あるいは書式ストリングが無効の場合、次のエラーメッセージが表示されます。「プロパティの「書式」は「inline」「block」もしくは有効な書式の文字列にしてください」。

"format": "notinline"

// Error : Property "format" is expected to be "inline", "block", or a valid format string.

修正するには、"format": 直後の設定値が "inline" もしくは "block" と等しく、また文字のつづりに間違いがないことを確認します。代わりの方法としてウィキ文であること、{{_|_=_}} は最少で、かつテンプレートの障害を防ぐため構文にエラーがないことを確かめ、とくに等号「=」が連続しないか大カッコ記号「{」と「}」のペアが崩れて片方だけ多い・足りない状態ではないかを確認します。カスタム書式の構文の詳細は#Custom formats節をご参照ください。 Alternatively, you can remove the "format" parameter to remove this error.

Unexpected property "parametername".

This error occurs if you state a parameter that does not exist in TemplateData. This is probably due to spelling mistakes.

<templatedata>
{
    "description": "",
    "format": "inline",
    "params": {
        "1": {
            "label": "",
            "descriptino": "", // <-- spelling mistake
            "type": ""
        }
    }
}
</templatedata>

It also occurs if you state a parameter in any TemplateData object that is not a parameter of that object. This may be due to spelling mistakes, or you may have written the parameter of one TemplateData object under another object that it doesn't belong to.

For example, you might have written the parameter "label" under the root TemplateData object instead of inside "params":

<templatedata>
{
    "description": "",
    "format": "inline",
    "label": "", // <-- incorrectly placed parameter
    "params": {
        "1": { // ↓ it should be in here
            "description": "",
            "type": ""
        }
    }
}
</templatedata>

別の方法として、if the unexpected parameter is under a template parameter inside "params", 内のテンプレートのパラメータに想定外のパラメータが含まれる場合、名称はエラー内の"パラメーター。parametername." 配下に表示します。

To fix this, make sure there aren't any spelling mistakes in the parameter names, and make sure your parameters are in their correct location. Additionally, make sure you don't state any parameters that don't exist for a TemplateData object. 特定のオブジェクトにどのパラメータが設定されているか、#TemplateData parametersの節をご参照ください。

Required property "params" not found.

This error occurs if there is no "params" object in the TemplateData. This is a necessary object, as it contains all the details of each parameter, so to fix this error, make sure it's added and that there are no spelling mistakes. "params" パラメータの追加方法は、このページの前述の節をご参照ください。
