ماڈیوٗل:WikidataIB/doc

This Lua module is used on many pages and changes may be widely noticed. Test changes in the module's /sandbox or /testcases subpages, or in your own module sandbox. Consider discussing changes on the talk page before implementing them.

For a more user-friendly wrapper of this module see {{wdib}}.

This module is intended to be used inside {{infobox}} (letters WikidataIB stand for Info Box, hence the name) or other templates and designed specifically to allow editors of an article (as opposed to editors of the infobox the article uses) to control whether Wikidata values are displayed.

One of the two sandboxes should be used for testing anything other than trivial amendments.

Test examples for the main module and the two sandboxes are available.

Overview

The module provides these calls specifically for use in infoboxes at present:

getValue - main call, used to get the value(s) of a given property
getQualifierValue - given: (1) a property; (2) its value; (3) a qualifier's propertyID, returns values which match
getValueByQual gets the value of a property which has a qualifier with a given entity value
getValueByLang gets the value of a property which has a qualifier P407("language of work or name") whose value has the given language code
getValueByRefSource gets the value of a property which has a reference "stated in" (P248) whose value has the given entity-ID
getPropOfProp if the value(s) of prop1 are of type "wikibase-item" then it returns the value(s) of prop2 of each of those wikibase-items
getAwardCat if the item has values of P166 (award received), then it examines each of those awards for P2517 (category for recipients of this award) and it returns the corresponding category, with the item's P734 (family name) as sort key, or no sort key if there is no family name
getIntersectCat for each value of the prop1 it fetches the value's main category and then each value of prop2, then it returns all of the categories representing the intersection of those properties
getSumOfParts scans the property 'has part' (P527) for values matching a list, If the matched values have a qualifier 'quantity' (P1114), those quantities are summed and returned (but zero returns nil)
getCoords - gets coordinates and passes them through {{Coord}}
getPreferredValue - Deprecated but retained for backward compatibility. Use the |getValue|rank=best parameters instead.

The obsolete call getSourcedValue has now been removed as it is redundant to getValue which can do the same job using the |onlysourced=true parameter (which is set by default).

Utilities functions

getLink if there is a sitelink to an article on the local Wiki, it returns a link to the article with the Wikidata label as the displayed text. If there is no sitelink, it returns the label as plain text. If there is no label in the local language, it returns the entity-ID
getAT (Article Title) If there is a sitelink to an article on the local Wiki, it returns the sitelink as plain text, otherwise nothing
getSiteLink gets the plain text link to an article on a given wiki
getLabel returns the Wikidata label for the local language as plain text. If there is no label in the local language, it returns the entity-ID
getAllLabels fetches the set of labels and formats it for display as wikitext
labelorid returns the label with all wikitext removed, or the entity-ID if no label
getDescription returns the article description for the Wikidata entity if the local parameter is "Wikidata".
getAllDescriptions fetches the set of descriptions and formats it for display as wikitext
getAliases returns the aliases for the entity in the current or given language
getAllAliases fetches the set of aliases and formats it for display as wikitext
pageId returns the connected Wikidata page id (entity-ID, Q-number) of the current page
formatDate takes a datetime of the usual format from mw.wikibase.entity:formatPropertyValues and formats it according to the df (date format) and bc parameters
formatNumber formats a number according to the supplied language code
checkBlacklist returns true if the field is not blacklisted (i.e. allowed)
emptyor returns nil if the parameter is just punctuation, whitespace or html tags, otherwise returns the argument unchanged
getLang returns the MediaWiki language code or the full language name of the current content
getItemLangCode looks for country (P17), then for that country's official language (P37), and returns its language code (P424)
findLanguage returns (1) supplied language if valid; or (2) the user's set language; or (3) the language of the current wiki
getQid returns (1) the entity-ID, if supplied; or (2) the entity ID of the "category's main topic (P301)"; or (3) the entity ID associated with the current page; or (4) nothing
followQid given a list of properties, looks for each property in turn and returns the entity-ID of the first value that matches (optionally, returns all entity-IDs that match)
getGlobe returns the entity-ID of the globe used in P625 (coordinate location), or nil if there isn't one
getCommonsLink returns one of the following in order of preference: the Commons sitelink of the linked Wikidata item; the Commons sitelink of the topic's main category of the linked Wikidata item;
siteID returns the root of the globalSiteID, e.g. "en" for "enwiki", "enwikisource", "en-gb", etc.
projID same as siteID
location scans from the current location upwards along the chain of higher-level locations, returning each one until it reaches a country
examine returns a formatted dump of the given property
url2 takes a parameter that is a proper url and formats it for use in an infobox; it accepts its own output as input
getWebsite fetches the Official website (P856) and formats it for use in an infobox
checkvalue looks through a property for a given entity-ID as its value and returns that entity-ID if found; otherwise nil
checkValidity returns whether the first unnamed parameter represents a valid entity-id
showNoLinks displays the article titles that should not be linked

Function getValue

Parameters to getValue

Name	Alias	Function	Default
(first unnamed)	1	The property-ID whose values are returned. Required.
(second unnamed)	2	A locally supplied value that, if it is not empty, will be returned in preference to the value on Wikidata.	empty
qid		The Q-number (entity-ID) of the entity that the property belongs to. If not supplied or empty, defaults to the associated Wikidata entry of the current page – uses mw.wikibase.getEntityIdForCurrentPage().	Item id for current page
eid		An alternative to qid. Except for `eid`, all parameters to getValue treat nil and the empty string the same. So, setting `\|x=` gives the same result as omitting the parameter. However, to provide some compatibility with other modules, using `\|eid=` always returns an empty string, while omitting `eid` allows `qid` to work as normal.	Item id for current page
rank		[Case insensitive] When set to `best`, returns preferred values if present, otherwise returns normal values. When set to `preferred` returns preferred values. When set to `normal`, returns normal values. When set to `deprecated` returns deprecated values. Any parameter value beginning with "b" is "best"; beginning with "p" is "preferred"; beginning with "n" is "normal"; beginning with "d" is deprecated. Multiple values are allowed: "p n d" would return all ranks. "Best" overrides the other flags. Other values are ignored and if no ranks are requested, preferred and normal are returned.	preferred and normal
qual		A punctuation-separated list of property-IDs of qualifiers that are to be returned in parentheses after the property. Setting `qual=ALL` returns all qualifiers. Setting `qual=DATES` returns آغاز وَقٕت (P580) and اِختِتام وَقٕت (P582) with a date separator.	none
qualsonly	qo	A boolean which enables the display of just the qualifier(s), without the property value or parentheses. Values `no`, `false` and `0` are all false; anything else is true.	false
fetchwikidata	fwd	List of fields to fetch values from. `ALL` fetches all fields. A value of `NONE` or blank or omitting the parameter fetches no fields.	none
suppressfields	spf	List of fields which will never display. This will even force a local value in the field not to display.	none
name		Name of the field. When encoding an infobox, this is the name that fetchwikidata and suppressfields will recognise. Required if fetchwikidata or suppressfields is specified (except when `fetchwikidata=ALL`).	nil
onlysourced	osd	A boolean which will filter out Wikidata values that are unsourced or only sourced to Wikipedia. This 2018 RFC requires that Wikidata values displayed in article infoboxes must be sourced. Values `no`, `false` and `0` are all false; anything else is true.	true
df		Date format: may be `dmy` (day before month) or `mdy` (month before day) or `y` (year alone).	dmy
qdf		Date format of qualifiers. If omitted, defaults to parameter `df`, or "y" if `df` is also omitted.	value of df or "y"
bc		Format of the BC/BCE suffix for dates.	BCE
plaindate	pd	String to modify formatting of dates. Setting "true"/"yes"/"1" disables adding "sourcing cirumstances" (P1480) and any links. Setting "adj" does the same but uses the adjectival form of the date.	false
linked		A boolean that enables the link to a local page via its sitelink on Wikidata. Values `no`, `false` and `0` are all false; anything else is true.	true
displaytext	dt	A string that overrides the displayed text of a linked item if it is non-empty.	empty
shortname	sn	A boolean that enables the use of shortname (P1813) instead of label for a linked item. Values `no`, `false` and `0` are all false; anything else is true.	false
uselabel	uselbl	A boolean that forces the display of the label instead of the disambiguated sitelink for a linked item. Labels are much more prone to vandalism that sitelinks. Values `no`, `false` and `0` are all false; anything else is true.	false
wdlinks	wdl	A boolean that enables the display of links to Wikidata when no local article exists. Values `no`, `false` and `0` are all false; anything else is true.	false
unitabbr	uabbr	A boolean that enables unit abbreviations for common units. Values `no`, `false` and `0` are all false; anything else is true.	false
convert	conv	A boolean that enables passing of quantities to Template:Cvt. Values `no`, `false` and `0` are all false; anything else is true.	false
showunits	su	A boolean that enables showing units for quantities. Values `no`, `false` and `0` are all false; anything else is true.	true
scale		A string that sets scaling for format of quantities. Values are: "a"=automatic; "0"=no scaling; "3"=thousand; "6"=million; "9"=billion; "12"=trillion.	0
maxvals		Sets the maximum number of values to be returned when multiple values are available. Setting it to 1 is useful where the returned string is used within another call, e.g. image. Values `0` and empty return all values.	0 (all)
collapse		Sets the maximum number of values to be returned before the content is auto-collapsed. Values `0` and empty allow all content to be displayed uncollapsed.	0 (all)
linkprefix	lp	A link prefix that is prepended to the linked value when linked. Applies only to items that have articles and to strings (e.g. url). It triggers linking of strings. Any double-quotes " are stripped out, so that spaces may be passed.	empty
linkpostfix		A link postfix that is appended to the linked value when linked. Applies only to items that have articles and to strings (e.g. url). It triggers linking of strings. Any double-quotes " are stripped out, so that spaces may be passed.	empty
prefix		A prefix that is prepended to the displayed value of strings (e.g. url). Any double-quotes " are stripped out, so that spaces may be passed.	empty
postfix		A postfix that is appended to the displayed value of strings (e.g. url). Any double-quotes " are stripped out, so that spaces may be passed.	empty
qlinkprefix	qlp	Qualifier link prefix (see linkprefix).	empty
qlinkpostfix		Qualifier link postfix (see linkpostfix).	empty
qprefix		Qualifier prefix (see prefix).	empty
qpostfix		Qualifier postfix (see postfix).	empty
sorted		A boolean which enables sorting of the values returned. Values `no`, `false` and `0` are all false; anything else is true.	false
qsorted		A boolean which enables sorting of the qualifier values within each item returned. Values `no`, `false` and `0` are all false; anything else is true.	false
noicon		A boolean which will suppress the trailing "edit at Wikidata" pen-icon. Useful for when the returned value is to be further processed. Values `no`, `false` and `0` are all false (i.e. shows the icon); anything else is true (i.e. suppresses the icon).	false
list		The name of a template that the list of multiple values is then passed through. Examples include "cslist", "hlist", "ubl", "blist", "olist", "p-1". A special value, `prose`, produces "1, 2, 3 and 4".	none
sep		Customises the string that is used to separate multiple returned values. Any double-quotes " are stripped out, so that spaces may be passed. If nothing or an empty string is passed it is set to the default list separator (", " in English).	", "
qsep		Customises the string that is used to separate multiple returned qualifier values. Any double-quotes " are stripped out, so that spaces may be passed. If nothing or an empty string is passed it is set to the default list separator (", " in English).	", "
format		Determines whether global coordinates should be rendered as degree/minute/second or as decimal degrees. Any value beginning "dec" (case insensitive) will render as decimal. Anything else will render as DMS.	dms
show		Determines how global coordinates should be returned. The value "longlat" will return `longitude, latitude`. Any other value beginning "lon" (case insensitive) will return just longitude. Any value beginning "lat" (case insensitive) will return just latitude. When used with `\|noicon=true`, all of these will be pure numbers in decimal degrees (signed: N and E as positive), which are intended for use in mapping templates, etc. Anything other value (or nothing) will render the usual coordinate values as DMS or decimal with "NSEW" qualifiers, etc.	empty
lang		Allows an unlinked value to be returned in the chosen language. Takes a standard ISO language code recognised by MediaWiki. If not supplied or blank, the local language (or set language for multi-lingual wikis) is used as normal.	local language
parameterset	ps	Convenience parameter to allow commonly used sets of parameters to be specified with a single parameter: ps=1 gets a simple linked value wherever possible; ps=2 represents a plain text value. See Parameter sets
linkredir		Boolean to switch on or off the check for a redirect with the same name as the label when there is no sitelink on Wikidata for the value. Values `no`, `false` and `0` are all false; anything else is true.	false

Base parameters

getValue can also take a named parameter |qid= which is the Wikidata ID for an article. This will not normally be used as omitting it defaults to the current article.
The property whose value is to be returned is passed in the first unnamed property and is required.
The second unnamed parameter, if supplied, will become the returned value and no call to Wikidata will be made.

Whitelist and blacklist

The name of the field that this function is called from is passed in the named parameter |name=, which is first checked against a blacklist of fields that are never to be displayed, (i.e. the call must return nil in all circumstances). If the field is not on the blacklist, it is then checked against a whitelist. If the name of the field matches, the call will return any locally supplied value if it is supplied as the second unnamed parameter, or the Wikidata value otherwise.
Specifying |fetchwikidata=ALL is a shortcut to return all fields that are not blacklisted.
The name is compulsory when the blacklist or whitelist is used, so the module returns nil if it is not supplied, other than when |fetchwikidata=ALL.
The blacklist is passed in the named parameter |suppressfields=
The whitelist is passed in the named parameter |fetchwikidata=

Sourcing

The getValue function will accept a boolean parameter onlysourced which will suppress return of Wikidata values that are unsourced or only sourced to a Wikimedia project. The absence of the parameter, an empty parameter (|onlysourced=) and the empty string ("") all default to true (i.e. only referenced values are returned). The values no, false and 0 are treated as false (i.e. all values are returned); any other value is true (although |onlysourced=yes/no is recommended for readability).

Link to Wikidata

The getValue function will accept a boolean parameter noicon which will suppress the trailing "edit at Wikidata" icon and link for cases when the returned value is to be further processed by the infobox (e.g. a url). The absence of the parameter or an empty parameter (|noicon=) default to false (i.e. the icon is added). The empty string ("") and the values no, false and 0 are treated as false; any other value is true (although |noicon=true is recommended for readability).

Following a discussion at Module talk:WikidataIB #Visibility of pen icon, the pen icon is hidden from users who are not autoconfirmed. This means that most readers don't see the pen icon, and represents a balance between aesthetics and vandalism at Wikidata on the one hand, and the desire to encourage editing Wikidata on the other.

Dates

In order to handle the requirement for dates in mdy, dmy or just year formats, getValue accepts a named parameter |df= that may take the values "dmy", "mdy", or "y" - default is "dmy".

As an article may require either of suffixes BC and BCE, getValue accepts a named parameter |bc= that may take the values "BC", or "BCE" - default is "BCE". Some test cases are shown at Module talk:WikidataIB/testing #Calls to getValue for dates.

Ranks

The |rank= parameter, when set to preferred, returns only preferred values; when set to normal, returns only normal values; when set to deprecated, returns only deprecated values. If the parameter is set to best, it returns preferred values if present, otherwise normal values. Any parameter value beginning with "p" is "preferred"; any parameter value beginning with "n" is "normal"; any parameter value beginning with "d" is "deprecated"; any parameter value beginning with "b" is "best". Combinations of values are allowed, e.g. |rank=p n returns all the preferred and normal values (which is the default), although "best" overrides any other parameters.

Specific value-type handlers

The module has specific handlers for the following data types:

Items that correspond to an article in some Wikipedia, called "wikibase-items". These will be linked to the corresponding (and disambiguated) article on English Wikipedia where possible.
Items that represent dates. These may be centuries, years, years and months, or years, months and days.
Items that represent Commons media, urls, external ids, or other sorts of plain text.
Items that represent quantities. All of these may have an associated unit, or be dimensionless, and may have a range.
Items that represent global coordinates. These will be in degrees of latitude and longitude and will have an associated precision.

Items that represent other types of data are not handled at present.

The third class of data types may be used with the parameters:

|prefix=, |postfix=, |linkprefix=, |linkpostfix=

If you don't supply at least one of |linkprefix= or |linkpostfix=, then just |prefix= and |postfix= are used. For example, when getting the (P717) in (Q532127):

{{#invoke:WikidataIB/sandbox|getValue|P717|fetchwikidata=ALL|onlysourced=no |prefix="before " |postfix=" after" |qid=Q532127}} → سِکرپٹ نُقُص: "WikidataIB/sandbox" ناو سٟتؠ چھُنہٕ کانٛہہ ماڈیوٗل موجوٗد.

Use double-quotes to enclose the parameter value if it has leading or trailing spaces (otherwise they are stripped out). If you supply |linkprefix= or |linkpostfix=, then all four parameters are used and a link is made for each value like this:

[[ linkprefix WikidataValue1 linkpostfix | prefix WikidataValue1 postfix]], [[ linkprefix WikidataValue2 linkpostfix | prefix WikidataValue2 postfix]], etc.

That allows multiple links to be made to different sections of a list article, such as List of observatory codes. For example, when getting the (P717) in (Q532127) we can make the links:

{{#invoke:WikidataIB/sandbox|getValue|P717|fetchwikidata=ALL|onlysourced=no |prefix= |postfix= |linkprefix="List of observatory codes#" |linkpostfix= |qid=Q532127}} → سِکرپٹ نُقُص: "WikidataIB/sandbox" ناو سٟتؠ چھُنہٕ کانٛہہ ماڈیوٗل موجوٗد.

The parameters |prefix=, |postfix=, |linkprefix=, |linkpostfix= are also applied to wikibase-items if they are linked.

Formatting multiple returned values

|sorted=<yes|no> is a boolean passed to enable sorting of the values returned. No parameter, or an empty string, or "false", or "no", or "0" disables sorting. It's only a very dumb alphabetical sort and sorts linked values as "[[ ..."
|sep=<separator characters> allows the separator between multiple returned values to be defined. The default is ", " (comma plus normal space). If the separator has leading or trailing spaces, enclose it in double quotes (e.g. |sep=" - "). Any double quotes are stripped from the separator. The pipe character (|) must be escaped as {{!}}. For reasons of accessibility (see ), do not use |sep=  for vertical unbulleted lists; use |list=ubl instead.
|list=<prose|cslist|hlist|ubl|blist|olist> allows multiple returned values to be displayed as a sentence with last two values separated by "and" (|list=prose), a horizontal comma-separated list (|list=cslist, not to be used in prose), a horizontal list (|list=hlist), a vertical unbulleted list (|list=ubl), a vertical bulleted list (|list=blist), or a vertical ordered list (|list=olist). These override the separator and do not display the 'pen icon' linked to "Edit at Wikidata".
|list=p-1 displays the last value. Combine with |maxvals=n to display the nth value.

Limiting the returned values

Sometimes a property is expected to have a single value, such as تَصویٖر (P18), but may have multiple values on Wikidata. Setting |maxvals=1 will limit the number of values returned to 1. Any other value is possible and functions as expected, but zero is treated as "no limit".

Unlinking

A returned value that represents an article on the local wiki will be linked by default. This includes redirects, but not dab pages. Sometimes there is a need not to link that returned values and this may be accomplished by setting |linked=no.

Unit abbreviations

When the returned value is a quantity, the name of the units in which it is expressed is appended. Infoboxes may wish to use abbreviations instead for common units. This can be done by setting |unitabbr=true.

Qualifiers

A parameter |qual= may be supplied, which will return qualifiers of the required property, if they exist. If the value is set to a punctuation-separated list of property-IDs (e.g. P123, P456), then only the values of qualifiers with that property will be returned. If the value is set to |qual=ALL, then all of the qualifier values are returned. If the value is set to |qual=DATES then the آغاز وَقٕت (P580) and the اِختِتام وَقٕت (P582) of the property are returned with a date separator. In each case, any qualifier values returned follow the property value, and are enclosed in parentheses. If multiple qualifier values are returned, they will be separated by commas by default, although the separator can be changed by specifying |qsep= (which may be enclosed in double-quotes, which are stripped out, so that spaces can be included). Setting the parameter |qsorted=yes will sort the returned qualifier values alphanumerically.

Short form of parameters

Some of the longer parameters may be abbreviated to make infobox designs more compact:

fwd → fetchwikidata
osd → onlysourced
spf → suppressfields
wdl → wdlinks

Parameter sets

Generally, getValue has a set of defaults for its parameters that represent consensus decisions by editors. For example, |onlysourced= defaults to true so only Wikidata values that are sourced to something better than "Wikipedia" will be returned, and |fetchwikidata= defaults to none so nothing is returned until it is enabled by setting some field names or "ALL". This represents the fail-safe condition and allows infoboxes to be made Wikidata-capable without changing any article until enabled for that article.

To simplify the use of getValue in other circumstances, common combinations of parameters can be specified with |parameterset= or its alias |ps= for convenience. Two combinations are implemented at present and these are:

ps=1: a common set of overrides to get a simple value, linked where possible:

|rank         ="best"
|fetchwikidata="ALL"
|onlysourced  ="no"
|noicon       ="true"

ps=2: a sort of raw value in plain text:

|rank          = "best"
|fetchwikidata = "ALL"
|onlysourced   = "no"
|noicon        = "true"
|linked        = "no"
|plaindate     = "true"

Other sets could be created if there is a demand.

Wrapper template

The template {{wdib}} can be used as a convenient wrapper for {{#invoke:WikidataIB |getValue}}.

Other main functions

Function getPreferredValue

The getPreferredValue function works exactly like getValue, taking the same parameters, but if any values for a property have the preferred rank set, it will only return those values. This is now deprecated in favour of getValue|rank=best.

Function getCoords

getCoords can also take a named parameter |qid= which is the Wikidata ID for an article. This will not normally be used as omitting it defaults to the current article.
The first unnamed parameter, if supplied, will become the returned value and no call to Wikidata will be made.
The coordinates from Wikidata are parsed and passed to Template:Coord which returns the display as if it were called manually.
The blacklist of fields that are never to be displayed, and the whitelist are implemented in the same way as for getValue using |suppressfields= and |fetchwikidata=
The format parameter sets the display format to decimal or dms. Any value beginning with "dec" sets decimal; anything else sets dms.
The display parameter sets the display position to "inline", "title" or "inline, title". Default is nothing (so uses default for {{Coord}}, currently "inline").

Function getQualifierValue

The getQualifierValue function is for use when we want to fetch the value of a qualifier. We need to know the property and the value of the property that the qualifier relates to. The parameters are:

The property ID passed in the unnamed parameter (or |1=)
The target value for that property in |pval=
The qualifier ID for that target value in |qual=
The same parameters to implement whitelisting and blacklisting of the property as in getValue
Optional boolean to specify whether only sourced values of the property are returned (defaults to "no") in |onlysourced=
Optional item ID for arbitrary access in |qid=
The same parameters to format output as in getValue

Example of getQualifierValue

In (Q1513315) there is a property قٲبلہٕ ذِکر (P793), which has a value (Q385378). That has two qualifiers, آغاز وَقٕت (P580) and اِختِتام وَقٕت (P582). To get the start date:

{{#invoke:WikidataIB |getQualifierValue |qid=Q1513315 |P793 |pval=Q385378 |qual=P580 |name=xyz |fetchwikidata=ALL }}

In South Pole Telescope it returns:

نَوَمبَر 2006

Function getValueByQual

The getValueByQual function returns the value of a property which has a qualifier with a given entity value. The parameters are:

The property ID passed in the unnamed parameter (or |1=)
The property ID for a qualifier (or "ALL" or "DATES") in |qualID=
The Wikibase-entity ID of a value for that qualifier in |qvalue=
The same parameters to implement whitelisting and blacklisting of the property as in getValue
Optional boolean to specify whether only sourced values of the property are returned (defaults to "no") in |onlysourced=
Optional item ID for arbitrary access in |qid=
The same parameters to format output as in getValue

Example of getValueByQual

In ماز (Q10990) there is a property (P443) that has multiple values, each of which has a qualifier ناو یا کامہِ ہٕنٛز زَبان (P407). We can return the property value whose qualifier has the value برطٲنوی اَنٛگریٖزی زَبان (Q7979)

{{#invoke:WikidataIB |getValueByQual |qid=Q10990 |P443 |qualID=P407 |qvalue=Q7979 |fwd=ALL |osd=no |noicon=true}} → سِکرپٹ نُقُص: "WikidataIB/sandbox" ناو سٟتؠ چھُنہٕ کانٛہہ ماڈیوٗل موجوٗد.

Function getValueByLang

The getValueByLang function returns the value of a property which has a qualifier ناو یا کامہِ ہٕنٛز زَبان (P407) whose value has the given language code. The parameters are:

The property ID passed in the unnamed parameter (or |1=)
The وِکیٖمیٖڈیا زَبان کوڈ (P424) to match the language whose code is given by |lang=xx[-yy]. If no code is supplied, it uses the default language.
The same parameters to implement whitelisting and blacklisting of the property as in getValue
Optional boolean to specify whether only sourced values of the property are returned (defaults to "no") in |onlysourced=
Optional item ID for arbitrary access in |qid=
The same parameters to format output as in getValue

Example of getValueByLang

In (Q7565108) there is a property وؠب سایِٹ (P856) that has multiple values, each of which has a qualifier ناو یا کامہِ ہٕنٛز زَبان (P407). We can return the property value whose ناو یا کامہِ ہٕنٛز زَبان (P407) qualifier value (a WD item) itself has the وِکیٖمیٖڈیا زَبان کوڈ (P424) property that is "ja", i.e, جاپأنؠ زبان (Q5287)

Utility functions

Function getLink

getLink has the qid of a Wikidata entity passed as the first unnamed parameter or as |qid=

If there is a sitelink to an article on the local Wiki, it returns a link to the article with the Wikidata label as the displayed text. If there is no sitelink, it returns the label as plain text. If there is no label in the local language, it displays the qid instead.

Function getLabel

getLabel has the qid of a Wikidata entity passed as the first unnamed parameter or as |qid=

It returns the Wikidata label in the local language for an item by the given qid. If there is no label in the local language, it returns the qid instead. Note that this is the label given to the Wikidata entry in the same language as the current Wiki, if the label exists.

Function label

label has the qid of a Wikidata entity passed as the first unnamed parameter or as |qid=

It returns the Wikidata label in the local language for an item by the given qid or linked to the current page. If there is no label in the local language, it returns an empty string. Note that this is the label given to the Wikidata entry in the same language as the current Wiki, if the label exists.

Function getAT

getAT has the qid of a Wikidata entity passed as the first unnamed parameter or as |qid=

If there is a sitelink to an article on the local Wiki, it returns the sitelink as plain text, i.e. the article title. If there is no sitelink, it returns nothing. Note that this is the title of the article in the current Wikipedia, if the interlanguage link exists in the Wikidata entry.

Function getDescription

getDescription has the qid of a Wikidata entity passed as |qid= (it defaults to the associated qid of the current article if omitted). It has a local parameter passed as the first unnamed parameter. Any local parameter passed (other than "Wikidata" or "none") becomes the return value. It returns the article description for the Wikidata entity in plain text if the local parameter is "Wikidata". Nothing is returned if the description doesn't exist or "none" is passed as the local parameter.

Function formatDate

formatDate accepts a datetime of the usual format from mw.wikibase.entity:formatPropertyValues, like "1 August 30 BCE" as parameter 1 and formats it according to the df (date format) and bc parameters.

{{#invoke:WikidataIB |formatDate | 1 August 30 BCE |bc=BCE |df=dmy}} → 1 August 30 BCE
{{#invoke:WikidataIB |formatDate | 1 August 30 BCE |bc=BC |df=mdy}} → August 1, 30 BC
df = "dmy" / "mdy" / "y" - default is "dmy"
bc = "BC" / "BCE" - default is "BCE"

Function checkBlacklist

checkBlacklist allows a test to check whether a named field is allowed. It returns true if the field is not blacklisted (i.e. allowed) It returns false if the field is blacklisted (i.e. disallowed)

Example:

{{#if:{{#invoke:WikidataIB |checkBlacklist |name=nationality |suppressfields=residence; nationality; citizenship}} | not blacklisted | blacklisted}} → not blacklisted
{{#if:{{#invoke:WikidataIB |checkBlacklist |name=birth_place |suppressfields=residence; nationality; citizenship}} | not blacklisted | blacklisted}} → not blacklisted

Function emptyor

emptyor returns nil if its first unnamed argument is just punctuation, whitespace or html tags otherwise it returns the argument unchanged (including leading/trailing space).

If the argument could contain "=", then it must be called explicitly:

| 1 = whatever-the-argument-is

In that case, leading and trailing spaces are trimmed.

It finds use in infoboxes where it can replace tests like:

{{#if: {{#invoke:WikidataIB |getvalue |P99 |fwd=ALL}} | {{#invoke:WikidataIB |getvalue |P99 |fwd=ALL}} | }}

with a form that uses just a single call to Wikidata:

{{#invoke |WikidataIB |emptyor |1= {{#invoke:WikidataIB |getvalue |P99 |fwd=ALL}} }}

Function labelorid

labelorid is a public function to expose the output of labelOrId().

The Q-number (entity ID) is passed as |qid= or as an unnamed parameter.

It returns the Wikidata label for that entity or the qid if no label exists.

Function getQid

getQid works with the current page and its associated Wikidata entry.
It returns qid, if supplied as the first unnamed parameter or as |qid=;
failing that, the Wikidata entity ID of the "category's main topic (P301)", if it exists;
failing that, the Wikidata entity ID associated with the current page, if it exists;
otherwise, nothing

Function examine

examine provides a dump of the entire property given in the first unnamed parameter (or in |pid= as a named alias) from the item given by the parameter 'qid', or from the item corresponding to the current page if qid is not supplied. Both parameters may be unnamed and given in any order.

It works in a similar manner to the Dump function, but only loads a single claim, rather than the whole Wikidata entry.

Example: {{#invoke:WikidataIB |examine |qid=Q1396889 |P50}}

There is a Template:Examine which acts as a wrapper for the call.

Example: {{examine |Q4048254 |P31}} →

فرما:Examine

Function url2

url2 takes a parameter url= that is a proper url and formats it for use in an infobox.

Examples:

-- Version: 2021-02-06 -- Module to implement use of a blacklist and whitelist for infobox fields -- Can take a named parameter |qid which is the Wikidata ID for the article -- if not supplied, it will use the Wikidata ID associated with the current page. -- Fields in blacklist are never to be displayed, i.e. module must return nil in all circumstances -- Fields in whitelist return local value if it exists or the Wikidata value otherwise -- The name of the field that this function is called from is passed in named parameter |name -- The name is compulsory when blacklist or whitelist is used, -- so the module returns nil if it is not supplied. -- blacklist is passed in named parameter |suppressfields (or |spf) -- whitelist is passed in named parameter |fetchwikidata (or |fwd)
