Module:Wd

Module documentation

This module is intended to fetch data from Wikidata with or without a link to the connected Wikipedia article and with many other features.

Usage

The general structure of a call to this module is as follows. Note that the basic structure consists of positional commands, flags and arguments, which all have a fixed position.

{{#invoke:wd |command1|flag1a|flag1b|flag1c |command2|flag2a|flag2b|flag2c |flag0a|flag0b|flag0c |arg1|arg2|arg3}}

Use different commands to get different kinds of values from Wikidata. At least one command must be given and multiple commands can be combined into one call as shown above (in any order, more than two is also possible), but this only applies to commands from the claim class; calls containing a command from the general class cannot contain any other command. Each command can be followed by any number of command flags, which are optional and can be used to tweak the output generated by that command.

The commands and their flags may be followed by any number of configuration flags, which are also optional and affect the selection of data and the module's behaviour in general. The call is closed with the positional arguments, which may be required depending on the given command(s). Some named arguments (i.e. name-value pairs) also exist, as well as a set of named flags for advanced usage that can be used to change the way the fetched values are merged together into the output.

This module was designed to provide the basic needs for fetching data from Wikidata, but a lot can be achieved through different combinations of calls. For convenience, such combinations could be wrapped into new templates that serve a specific need. See also the section on common use cases below for some examples of useful "building blocks". Likewise, the functionality of this module can be extended by creating wrapper templates that use the main command provided by this module (just like {{WikidataOI}} does).

Common use cases

Below follows a list of common use cases. In the future, shortcut commands may be implemented that are equivalent to these calls for convenience.

Call	Use case
`{{#invoke:wd\|label\|raw}}`	Returns the Q-identifier of the Wikidata item connected to the current page (e.g. "Q55").
`{{#if:{{#invoke:wd\|label\|raw}}\|...}}`	Performs a check to determine if the current page has a Wikidata item. Note that this statement relies on a returned value that is either empty or non-empty and that the `raw` flag is important to include. Without this flag, an existing item's regular label would be returned which could be empty, giving an undesired result. If the flag is given on the other hand, then a non-empty Q-identifier is always returned if an item exists and an empty value if an item does not exist.

Commands

The commands (command1, command2, ...) determine what kind of values are returned. One call can only contain commands from a single class.

Claim class

The claim class commands can be combined, meaning that multiple commands of different types from this class can be given at one time (see above for usage).

Combine multiple commands into one call to this module, instead of making multiple calls to this module with one command each, to be sure that all the returned pieces of information belong to each other (see also the examples below).

Type	Command	Returns	Basic usage	Description
I	`property`	first match^[a]	`{{#invoke:wd\|property\|P1}}`	Returns the requested property – or list of properties – from the current item-entity or from a given entity. This command can be given only once in one call.
I	`properties`	all matches	`{{#invoke:wd\|properties\|P1}}`

II	`qualifier`	first match^[b]	`{{#invoke:wd\|qualifier\|P1\|P2}}`	Returns the requested qualifier – or list of qualifiers – from the given property of the current item-entity or of a given entity. Unlike the other claim class commands, this command can be given multiple times to retrieve different qualifiers in one call.
II	`qualifiers`	all matches	`{{#invoke:wd\|qualifiers\|P1\|P2}}`

III	`reference`	first match^[b]	`{{#invoke:wd\|reference\|P1}}`	Returns a reference – or list of references – from the given property of the current item-entity or of a given entity.^[c] This command can be given only once in one call.
III	`references`	all matches	`{{#invoke:wd\|references\|P1}}`

General class

The general class commands cannot be combined.

Type	Command	Returns	Basic usage	Description
I	`label`		`{{#invoke:wd\|label}}`	Returns the label of the current item-entity or of a given entity if present.

II	`title`		`{{#invoke:wd\|title}}`	Returns the title of the page connected to the current item-entity or to a given item-entity if such page exists.

III	`description`		`{{#invoke:wd\|description}}`	Returns the description of the current item-entity or of a given entity if present.

IV	`alias`	first match^[a]	`{{#invoke:wd\|alias}}`	Returns an alias – or list of aliases – of the current item-entity or of a given entity if present.
IV	`aliases`	all matches	`{{#invoke:wd\|aliases}}`

V	`badge`	first match^[a]	`{{#invoke:wd\|badge}}`	Returns a badge – or list of badges – for the page connected to the current item-entity or to a given item-entity if such page exists.
V	`badges`	all matches	`{{#invoke:wd\|badges}}`

Flags

The following (optional) flags are available which can be used to alter this module's behaviour. They must be given after the (first) command and before the positional arguments. For convenience, empty flags (i.e. ||) are allowed and will simply be ignored.

Command flags

These flags (flag1*, flag2*, ...) apply to the command that precedes them directly.

Flag	Description
`raw`	Returns the raw value if applicable. If this flag is used with item or property datatypes, then this will return the Q-identifier or P-identifier instead of the regular label. For quantity datatypes, this flag will strip off any units of measurement, unless the `unit` flag is also given in which case the raw unit of measurement (its Q-identifier) will be returned. If this flag is used with time datatypes, then the returned date will be in the format of `yyyy-mm-dd` (e.g. `1731-02-11`), or `yyyy-mm`, or `yyyy` depending on the date's precision. Dates in the Julian calendar stored with a precision of days through millenniums will have `/Julian` attached to the output (e.g. `1731-02-11/Julian`, which may be split off using the {{#titleparts}} parser function). If it is used with globe coordinate datatypes, then it replaces the various symbols with forward slashes in the returned value (e.g. `52/5/3/N/4/19/3/E`, which may be split into parts using the {{#titleparts}} parser function).
`linked`	Creates a link to the Wikipedia article that is connected to the property or qualifier if it exists. Also links units of measurement that may be appended to values. If this parameter is omitted, then the plain property or qualifier value will be returned.
`short`	`[EXPENSIVE]` Returns the short name (P1813) of any entity returned if they have one attached. If that is not the case, then the default behaviour of returning the entity's label will occur.
`multilanguage`	Returns monolingual text values in any available language, not just the current wiki's language.
`unit`	Returns only the unit of measurement for quantity datatypes.

Configuration flags

These flags (flag0*) are general configuration flags and can be given anywhere after the first command (but before the positional arguments).

	Flag	Description	Command class
Combination of:	`preferred`	Sets a rank constraint for the selected claim(s). The first three set the ranks for which claim(s) will be selected. They can optionally be followed by a `+` or a `-`, e.g. `normal+` or `preferred-`, where the first selects claims with a 'normal' rank or higher and the second selects claims with a 'preferred' rank or lower. To get claims of all ranks, use `preferred-` or `deprecated+`. If the `best` flag is given additionally, then only the claims that have the highest rank amongst the selected claims will be returned. The default is `normal+\|best` (so by default claims with a 'deprecated' rank are never returned). Output is always sorted from highest rank to lowest (regardless of any of these flags being set).	claim
	`normal`
	`deprecated`
	`best`
Combination of:	`future`	Sets a time constraint for the selected claim(s). Uses the claims' qualifiers of start time (P580) and end time (P582) to determine if the claim is valid for the selected time period(s). The default is `future\|current\|former` (so by default claims that are valid for any time period are returned), except when `date=` is given (see below) in which case the default is `current`.	claim
	`current`
	`former`
	`mdy`	Returns date values in month-day-year order instead of day-month-year order.	claim
	`single`	Returns only a single claim instead of multiple (if multiple claims match). Has no effect if the `property`/`properties` command is given, in which case this flag would be redundant.	claim
	`sourced`	Only returns claims that have at least one non-empty reference. (References having only ignored parameters are considered empty.)	claim
One of:	`edit`	Adds a clickable icon after the output that may be used by readers to edit the returned claim on Wikidata. If `edit@end` is used, then the icon will be placed at the end of the line for neat alignment in infoboxes.	claim, general
One of:	`edit@end`		claim, general

Arguments

The arguments determine the sources from which all the returned values are fetched.

Positional arguments

The following table shows the available positional arguments (arg*) in their fixed order. For each command, the applicable set of arguments is marked. If multiple commands are given, then the applicable set is the union of the individual sets. For instance, if the commands properties and qualifiers have been given, then at least both the arguments property_id and qualifier_id should be given as well.

More than one qualifier/qualifiers command can be given. The order in which these commands with their flags are given matches the order in which the respective qualifier_id arguments are given.

	(required)	(optional)	(optional)	(required)	(optional)	(required)	(required)

`{{#invoke:wd`	`commands`	`flags`	`entity_id`	`property_id`	`raw_value`	`qualifier_id`	`qualifier_id`	`}}`

			`label`, `title`, `description`, `alias`/`aliases`, `badge`/`badges`

			`property`/`properties`
			`property`/`properties`
			`reference`/`references`
			`reference`/`references`
			`qualifier`/`qualifiers`
			`qualifier`/`qualifiers`
			`qualifier`/`qualifiers` (optional 2^nd, 3^rd, etc.)
			`qualifier`/`qualifiers` (optional 2^nd, 3^rd, etc.)

Below follows a description of all positional arguments.

Argument	Description
`entity_id` (optional)	`[EXPENSIVE]` Q-identifier of the item-entity to be accessed (e.g. `Q55`), P-identifier (or an available alias) of the property-entity to be accessed preceded by the `Property:` prefix (e.g. `Property:P38`), or page title of the Wikipedia article whose connected item-entity is to be accessed preceded by `:`, a prefixed colon (e.g. `:Netherlands`). In case of the general class commands, the `Property:` prefix may be omitted for P-identifiers (e.g. `P38`). If this parameter is omitted, then the item-entity connected to the current page will be used (except when `eid=` or `page=` is given, see below). If this parameter is given, but empty (i.e. `\|\|`), then due to its position it will be interpreted as an empty flag and thus be ignored, giving the same result as if it were omitted. See also the named arguments `eid=` and `page=` below that can be used to give an entity-ID or page title too, but without the item-entity connected to the current page being used as a default.
`property_id`	P-identifier (or an available alias) of the property within the entity to be accessed, without the `Property:` prefix (e.g. `P35`).
`raw_value` (optional)	Either the Q-identifier equal to the property value (e.g. `Q29574`) or a literal value (i.e. string or quantity etc., no entity label) equal to the raw property value of the particular claim to be accessed. Dates as literal values must be formatted `yyyy-mm-dd` (e.g. `1731-02-11`) for dates with a precision of days, `yyyy-mm` (e.g. `1731-02`) for dates with a precision of months, and `yyyy` (e.g. `1731`) for dates of lesser precision. Dates BCE require a minus sign in front of the year (e.g. `-2950-01-31`). Dates stored in the Julian calendar must have `/Julian` attached to the end (e.g. `1731-02-11/Julian`). Decades like the 2010s must be given as `2010` (but the 2010s BCE as `-2019`), centuries like the 20th century as `1901` (but the 20th century BCE as `-2000`), and millenniums like the 3rd millennium as `2001` (but the 3rd millennium BCE as `-3000`). Globe coordinates as literal values must be formatted with forward slashes (i.e. `/`) between the parts and no symbols (e.g. `52/5/3/N/4/19/3/E`) without any spaces or leading zeros. The special type 'no value' can be given by entering the empty string (i.e. `\|\|`) and the special type 'unknown value' can be given by entering a single underscore (i.e. `\|_\|`). To get a literal underscore, escape it by placing a backslash `\` directly in front of it (i.e. `\_`); the same holds for a literal backslash (i.e. `\\`). To get a literal vertical bar `\|`, use `{{!}}` or `\|`. If this parameter is omitted, then all claims (matching any other constraints) within the property will be accessed.
`qualifier_id`	P-identifier (or an available alias) of the qualifier within the entity to be accessed, without the `Property:` prefix (e.g. `P580`).

Named arguments

Below follows a description of all named arguments, which are name-value pairs (i.e. |name=value). These are all optional and can be given anywhere after the first command.

Argument	Description	Command class
`eid=`	`[EXPENSIVE]` This argument can be used to give the Q-identifier (e.g. `\|eid=Q55`) or P-identifier (or an available alias) of the entity to be accessed. It offers the same functionality as the positional argument `entity_id`, with one difference: if the argument is given but its value is left empty (i.e. `\|eid=`), then no entity is accessed at all instead of the item-entity connected to the current page. This is useful in some cases where a variable entity-ID is expected, but where the item-entity connected to the current page should not be accessed as the default. Also, the `Property:` prefix may be omitted for P-identifiers (e.g. `\|eid=P38`) for all commands. This argument only has effect if the positional argument `entity_id` is omitted.	claim, general
`page=`	`[EXPENSIVE]` This argument can be used to give the page title (e.g. `\|page=Netherlands`) of the Wikipedia article whose connected item-entity is to be accessed. It behaves similar to the named argument `eid=` and can be used instead of the positional argument `entity_id` (note that no prefixed colon, `:`, is required). If the argument is given but its value is left empty (i.e. `\|page=`), then no entity is accessed at all instead of the item-entity connected to the current page. This argument only has effect if the positional argument `entity_id` and the named argument `eid=` are omitted.	claim, general
`date=`	This argument can be used to set a particular date (e.g. `\|date=1731-02-11`) relative to which claim matching using the `future`, `current` and `former` flags is done, instead of relative to today. It overrides the default of these flags to `current` so that by default only claims that were valid at the given date are returned (based on the claims' qualifiers of start time (P580) and end time (P582)). The date value must be formatted `yyyy-mm-dd` (e.g. `1731-02-11`), `yyyy-mm` (e.g. `1731-02`) or `yyyy` (e.g. `1731`).	claim
`<qualifier>=`	The `<qualifier>` is a placeholder for a set of arguments that determine which claims should be accessed based on qualifier value, analogous to the pair of positional arguments `property_id` and `raw_value` (that determine access based on property value). As such, `<qualifier>` is any qualifier's P-identifier (or an available alias) without the `Property:` prefix (e.g. `P518`). Its value is either the Q-identifier equal to one of the qualifier values (e.g. `Q27561`) or a literal value (i.e. string or quantity etc., no entity label) equal to one of the raw qualifier values of the particular claim to be accessed. The value format is the same as for the positional argument `raw_value`. The special type 'no value' given by the empty string also matches the total absence within the claim of the particular qualifier. Example: `\|P518=Q27561` Multiple arguments of this type can be given to match multiple qualifier values simultaneously for each claim.	claim

Property aliases

Property aliases are other names for P-identifiers that can be used instead. The following property aliases (which are case-sensitive) are currently available:

References

When either the reference or the references command is used and a reference is encountered (in Wikidata), the module attempts to display it using the {{Cite web}} template. The reference to be displayed has to have at least title (P1476) and reference URL (P854) properties. The below table shows the mapping of Wikidata properties to parameters of Cite web.


Wikidata property	Parameter of Cite web	Notes
archive date (P2960)	archive-date
archive URL (P1065)	archive-url
author (P50)	authorN	N can be 1, 2, 3...
author name string (P2093)	authorN	N can be 1, 2, 3...
language of work or name (P407)	language	Ignored when the same as the local language.
page(s) (P304)	pages
publication date (P577)	date
publisher (P123)	publisher
quotation (P1683)	quote
reference URL (P854)	url
retrieved (P813)	access-date	Ignored when Wikimedia import URL (P4656) is present but reference URL (P854) is not.
section, verse, paragraph, or clause (P958)	at
stated in (P248)	website
subject named as (P1810)	title	Used only when title (P1476) is not present, but a URL (either from reference URL (P854) or from an external identifier, as described below) is, otherwise ignored.
title (P1476)	title

The following properties are ignored: image (P18), imported from Wikimedia project (P143), inferred from (P3452), type of reference (P3865), Wikimedia import URL (P4656).

If there is no reference URL (P854) property present in the reference, but a property of the "External identifier" data type is present both in the reference and in the Wikidata property (P1687) of the item in stated in (P248), a URL is generated from its content and is used in the same manner as a URL given in reference URL (P854).

If a title (P1476) or a reference URL (P854) property is missing or the reference has unknown properties, the module attempts to display it using the {{Cite Q}} template. The stated in (P248) property is needed. It's used for the first (unnamed) parameter of Cite Q. The below table shows the mapping of other properties to Cite Q parameters.


Wikidata property	Parameter of Cite Q	Notes
chapter (P792)	chapter
column (P3903)	at
page(s) (P304)	pages
publication date (P577)	date
retrieved (P813)	access-date
section, verse, paragraph, or clause (P958)	section
title (P1476)	title
any property of the "External identifier" data type	id	The label of the property is prepended before its content.

The properties listed under the first table (in this section) are also ignored when using Cite Q.

A reference could be displayed using Cite Q only if the reference has a stated in (P248) property and has only properties listed in the table above. If neither Cite web nor Cite Q could be used to display a reference, the following error is returned:

Error: Unable to display the reference properly. See the documentation for details.

To fix this error, check if the reference has the required properties and doesn't have any unknown properties, as described above. The Wikidata help page on references can also be helpful when sourcing statements.

Note: Users copying this template/module to another wiki: The local names of the Cite web and Cite Q templates are fetched from the sitelinks of the Q5637226 or the Q22321052 item, respectively. If the local citation template isn't linked from its Wikidata item or it doesn't exist at all, this module skips attempting to display citations using it.

Advanced usage

The layout of the output from (a combination of) commands that have both a singular and a plural form (e.g. property/properties) can be customized by using a number of named flags, which are name-value pairs (i.e. |flag=value), that can be given anywhere after the first command. The table below shows the available named flags.

To insert a space at the beginning or end of a value, use an underscore _. To get a literal underscore, escape it by placing a backslash \ directly in front of it (i.e. \_); the same holds for a literal backslash (i.e. \\). To get a literal vertical bar |, use {{!}} or |.

Named flag Default value Default condition Description

format=

%p[%s][%r]

if the property/properties command was given and the qualifier/qualifiers command was not given

The format of a single claim. The available parameters are as follows.

Parameter	Description
`%p`	The claim's property value applied by the `property`/`properties` command.
`%q1`, `%q2`, `%q3`, ...	The claim's qualifier value or list of qualifier values applied by the corresponding `qualifier`/`qualifiers` command.
`%q`	The collection of the qualifier values applied by each `qualifier`/`qualifiers` command (i.e. `%q1` + `%q2` + `%q3` + ...). If only one `qualifier`/`qualifiers` command was given, then this parameter is equivalent to `%q1`.
`%r`	The claim's reference value or list of reference values applied by the `reference`/`references` command.
`%a`	The entity's alias applied by the `alias`/`aliases` command.
`%b`	The entity's page badge applied by the `badge`/`badges` command.
`%s`	The movable separator placeholder. This is a special parameter that is not applied by a command, but instead is filled automatically between each pair of claims, aliases or badges (if a list of claims, aliases or badges is returned). This is particularly handy in case a claim's reference is returned as well, since it allows the reference to be placed after the punctuation mark as prescribed by Wikipedia's manual of style. The default value is a comma (`,`) and can be overridden with the `sep%s` flag (see below).

Optional parameters can be given by encapsulating them between square brackets: [...]. All content between the square brackets is only displayed if a value for each optional parameter that has been defined between the same brackets has been found. Optional content can also be nested.

To use two opening square brackets that directly follow each other (i.e. [[), use {{!((}}.

At least one parameter must be given that is not optional, while the %s parameter must always be defined as optional.

To get a literal [, ], % or \, escape the character by placing a backslash \ directly in front of it (e.g. \%). See also the description directly above this table for more.

%q[%s][%r] if the property/properties command was not given and the qualifier/qualifiers command was given

%r if only the reference/references command was given

%p[ <span style="font-size:85\%">(%q)</span>][%s][%r]

if the property/properties command was given and the qualifier/qualifiers command was given

%a[%s] if the alias/aliases command was given

%b[%s] if the badge/badges command was given

sep= _ default The fixed separator between each pair of claims, aliases or badges.

if only the reference/references command was given without the raw flag

sep%s= , default The movable separator between each pair of claims, aliases or badges. This will be the value of the %s parameter applied to all claims, aliases or badges, except for the last in the list (which can be set with the punc flag).

; if the property/properties command was not given and the qualifier/qualifiers command was given

sep%q1=, sep%q2=, sep%q3=, ...

,_

default

The separator between each pair of qualifiers of a single claim. These are the value separators for the %q1, %q2, %q3, ... parameters.

If only one qualifier/qualifiers command was given, then the sep%q1 flag is equivalent to sep%q.

sep%q=

,_

if exactly one qualifier/qualifiers command was given

The separator between each set of qualifiers of a single claim. This is the value separator for the %q parameter.

If only one qualifier/qualifiers command was given, then this flag is equivalent to sep%q1.

;_ if more than one qualifier/qualifiers command was given

sep%r= default The separator between each pair of references of a single claim. This is the value separator for the %r parameter.

_ if the raw flag was given for the reference/references command

punc=

default

A punctuation mark placed at the end of the output. This will be placed on the %s parameter applied to the last claim (or alias or badge) in the list.

This allows the last claim's references to be placed after the punctuation mark when the output is used as part of a sentence.
