Tɛmplet:Authority control

Template documentation[view] [edit] [history] [purge]

Description

Further information: Authority control and Wikipedia:Authority control

This template links Wikipedia articles to various library (and other) catalogue systems, for biographies and other topics.

This template draws its values from Wikidata. A pencil icon gives convenient access to the "Identifiers" section of the corresponding Wikidata item.

Empty instances

If there is no information in Wikidata for the specific subject, an empty instance of this template will be dormant, meaning it will be invisible on the rendered page. Thus, using this template on a page with no authority information is harmless. An empty instance of this template stays dormant in an article, until values are added to Wikidata, when it will then display them.

Validation

The template attempts to validate digits for all values and shows an error if the check fails.

Position

See also: Wikipedia:Manual of Style/Layout

As a metadata template, the Authority control template should be placed on a new line, after the external links section and navigation templates, immediately before the categories.

Usage

{{Authority control}}

As a general guideline:

1. Insert the empty version
2. Click "Show preview" to see which sources are automatically pulled from Wikidata
3. If you know of more sources, add those sources to the article's Wikidata item, so that other language versions of Wikipedia will automatically benefit.

Suppression of identifiers

Identifiers can be selectively suppressed via the |suppress= parameter. For example Tɛmplet:Q can be suppressed by typing:

{{Authority control |suppress=P434}}

Specifying the Wikidata item

If a page is not connected to a Wikidata item (for example, a page in draft space, user space or project space), you can specify the appropriate item to draw data from, by using the |qid= parameter.

{{Authority control |qid=Q49605590}}

To find the correct item, you can search the database. If there is not yet an existing item, you can create a new item.

As soon as the page is connected to a Wikidata item, this parameter will be ignored so you can remove it from the template.

Additional Wikidata items

In some cases, you might need to specify additional items to draw data from. For example,

• Bonnie and Clyde also draws data from Tɛmplet:Q and Tɛmplet:Q
• North Rona also draws data from Tɛmplet:Q

To specify additional items, you can use the |additional= parameter. For example: {{Authority control | additional = Q2319886, Q3320282}}

To automatically add additional links from related items, use |additional=auto. This is useful for married couples, musical groups, etc.

Whitelists

A number of whitelists are configured, which allow only a limited selection of identifiers to be displayed. These can be used with the |show= parameter. For example, including |show=arts will only show identifiers which have identified as particularly relevant to the arts.

Multiple whitelists may be used. For example: {{Authority control|show=arts,SV}} adds identifiers from the arts and Sweden whitelists.

|country= can be used as an alias for |show= (but they can't both be used simultaneously).

List of whitelists

Examples

Victor Hugo

{{Authority control |qid=Q535}}

Alexander Graham Bell

{{Authority control |qid=Q34286}}

Harry Forbes Witherby

{{Authority control |qid=Q352545}}

Carl Larsson

{{Authority control (arts) |country=SV |qid=Q187310}} Tɛmplet:Authority control (arts)

Rendering

The template is split into a number of sections, including "International", "National", "Academics", "Artists" etc. The template usually displays as a navbox with a header:

If all identifiers are in the same section, |state= is ignored, and the template displays on one line.

If you use additional qids to draw data from additional wikidata items, then a new section will be added for each. In this case, the identifiers will not be separated further:

Initial visibility: currently defaults to autocollapse

To set this template's initial visibility, the |state= parameter may be used:

• |state=collapsed: {{Authority control|state=collapsed}} to show the template collapsed, i.e., hidden apart from its title bar
• |state=expanded: {{Authority control|state=expanded}} to show the template expanded, i.e., fully visible
• |state=autocollapse: {{Authority control|state=autocollapse}}
  • shows the template collapsed to the title bar if there is a {{navbar}}, a {{sidebar}}, or some other table on the page with the collapsible attribute
  • shows the template in its expanded state if there are no other collapsible items on the page

If the |state= parameter in the template on this page is not set, the template's initial visibility is taken from the |default= parameter in the Collapsible option template. For the template on this page, that currently evaluates to autocollapse.

Microformat

The template wraps each UID value with the HTML markup: <span class="uid">...</span>, which enables the first-found value to be included in an hCard microformat.

List of identifiers

The template gets its information from the following properties on Wikidata:

Additional tracking categories

This template may add the following categories:

• Category:Pages with authority control identifiers needing attention (243) – category to track errors
  • Category:Pages using authority control with parameters (0) – identifiers should be migrated to Wikidata
  • Category:All articles with faulty authority control information (0) - faulty identifiers to fix

What is template data?

Template data is the standardized description of a template, used by the default VisualEditor, the optional 2017 wikitext editor and other tools to improve the template-editing experience for the user. Both VisualEditor and the 2017 wikitext editor include a wizard to edit templates, but for the wizard to be most useful, it needs to present specific information to the user about each template, such as a short description of the template's purpose and its parameters. This information is codified formally (by any wiki editor) using template data.

Editing without template data

Without template data, each parameter needs to be added manually when inserting a new template.

No information is provided about what the value of the parameter should be.

Editing with template data

With template data, a list of supported parameters (and their description) is provided for the template.

Template data provides context for each parameter, and makes it much easier for users to modify templates.

Adding template data

Anyone can help by adding template data to templates (particularly high-profile ones, such as infoboxes) so that they are easier to edit in VisualEditor. The following is a minimal example, placed on a template's documentation page:

<templatedata>{
  "description": "insert description here",
  "params": {
    "first parameter": {
      "label": "x",
      "description": "x",
      "type": "string",
      "suggested": true,
      "autovalue": "derived automatic value",
      "default": "default value",
      "required": false
    }
  }
}</templatedata>

You can also add or edit template data using a GUI, by pressing the following button which appears at the top of the edit page: Edit template data

The template data tutorial explains in detail how to add template data information to a template.

Adding suggested values for parameters

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 with no coding required. Both methods are explained in detail below.

Once the values have been added to template data, the VisualEditor will display them in a combo box (a dropdown into which users can also enter a custom value). 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.

For suggested values to be displayed in the VisualEditor, the parameter’s type must be 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 dropdown menu for suggested values in the VisualEditor.

Adding suggested values for parameters 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.

An example might look like this:

"media_type": {
	"label": "Type of media",
	"example": "Newspaper",
	"type": "string",
	"description": "In what medium was the article published?",
	"suggestedvalues": [
    	"Journal",
    	"Book",
    	"Newspaper",
    	"Magazine"
	]
}

Adding suggested values for parameters with the template data editor

For the parameter types listed above, you can add suggested values using the template data editor.

Step 1. Click on "Manage TemplateData".
Step 2. Click on the name of the parameter you want to add suggested values to.
Step 3. If it’s not already, set the type of the parameter 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.
Step 4. Type in the suggested value(s), including any spaces and special characters, and press enter to add it to the list.

Here you can see an example of how to add suggested values in the TemplateData editor.
