什么是TemplateData?
TemplateData是一种存储模板与它的参数信息的储存格式，可视化编辑器能够解释并显示它们，以方便可视化编辑器使用者更好地使用模板.

TemplateData允许用户在模板页内写入一个小型的结构信息，或者编合到模板页中（如在模板说明页）. 当一个模板有了它自己的结构信息，这就能在可视化编辑器中显示. 虽然听上去好像很复杂，但实际上这很简单.



TemplateData的结构
TemplateData的结构基于JSON，相当简洁. 里面的说明应该是纯文字（不允许任何格式化）.

首先我们见建立包含这对 标记的页面，可以在模板说明页的任何位置，好像这样：

这回告诉软件这个标记之间的信息就是TemplateData信息，当这个模板被使用时就会被引用.



例子
这里有一个TemplateData标准例子：这个例子是对应一个叫“Commons”的模板，用以连接到Commons的一个主题分类上. 这里需要一个必须的参数：一个在Commons的分类名称. 这个模板的TemplateData可能看上去是这样.

This would display, in the template, like so: {       "description": "A template for linking to a commons category about an article", "params": { "1": {                       "label": "Commons category", "description": "The commons category you want to link to.", "default": "Category:CommonsRoot", "type": "string", "required": true }       } }



Description and parameters
Once you're done, hit "save". If you've made errors, it will not let you save (which is disruptive, but means you can't break anything). Should you run into errors, explain on the feedback page what you were trying to do, and we will be happy to help.

Note that each bit of information is enclosed in quotation marks (except for  and  ), and separated from the next bit by a comma (unless it's the last one).



Parameter aliases
Some templates allow a same parameter to have different names.

For example,  could also be written as   or.

To add this information to TemplateData, you simply need to add the aliases to the parameter's information:



Multiple parameters
If you have multiple parameters, just repeat each section (starting from the "1" tag) and fill it out as you see fit. Note that if a template has multiple parameters, you need to separate them with a comma in the templatedata, like so:



Similar parameters
When a template has multiple parameters, sometimes some of them can be of the same kind. In this case, you only need to provide full properties for the first one, and the others can "inherit" their properties from it.



Blank boilerplate
You can copy the blank boilerplate below to add new TemplateData to a template. Only the most common tags are included.



Limitations and questions

 * Missing features — TemplateData is very much an example of tool that was made available with few features, in hope that users would help to guide development of features that they desired. If you'd like to request new features for TemplateData, please let us know.
 * Delays in showing in templates — After adding TemplateData to a template, the metadata should be visible immediately when the template is opened in VisualEditor. However, it is possible that it takes hours before the metadata show. You can force an update by making a null edit to the template page itself (not the documentation subpage). To perform a null edit, open the template page for editing, and save the page without making any change.
 * Current issues — A list of current bugs and feature requests is available in bugzilla.



Tools

 * TemplateDataEditor — A user script that makes the process of adding TemplateData easier. It currently exists in English and French, and can easily be translated into other languages.
 * TemplateData Wizard — A tool that generates TemplateData through an interactive interface.
 * Skeleton TemplateData generator — A tool that reads the source wikicode of a template, tries to find all the parameters used and outputs a skeleton document with the parameters listed.
 * JSONLint — A tool that allows you to validate manually-written JSON to help find errors in the syntax.
