Module:WikidataIB/doc explained

This module is intended to be used inside (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:

  1. getValue - main call, used to get the value(s) of a given property
  2. getQualifierValue - given: (1) a property; (2) its value; (3) a qualifier's propertyID, returns values which match
  3. getValueByQual gets the value of a property which has a qualifier with a given entity value
  4. getValueByLang gets the value of a property which has a qualifier P407("language of work or name") whose value has the given language code
  5. getValueByRefSource gets the value of a property which has a reference "stated in" (P248) whose value has the given entity-ID
  6. 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
  7. 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
  8. 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
  9. 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)
  10. getCoords gets coordinates and passes them through
  11. getPreferredValue - 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 parameter (which is set by default).

Utilities functions

  1. 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
  2. getAT (Article Title) If there is a sitelink to an article on the local Wiki, it returns the sitelink as plain text, otherwise nothing
  3. getSiteLink gets the plain text link to an article on a given wiki
  4. 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
  5. getAllLabels fetches the set of labels and formats it for display as wikitext
  6. labelorid returns the label with all wikitext removed, or the entity-ID if no label
  7. getDescription returns the article description for the Wikidata entity if the local parameter is "Wikidata"
  8. getAllDescriptions fetches the set of descriptions and formats it for display as wikitext
  9. getAliases returns the aliases for the entity in the current or given language
  10. getAllAliases fetches the set of aliases and formats it for display as wikitext
  11. pageId returns the connected Wikidata page id (entity-ID, Q-number) of the current page
  12. 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
  13. formatNumber formats a number according to the supplied language code
  14. checkBlacklist returns true if the field is not blacklisted (i.e. allowed)
  15. emptyor returns nil if the parameter is just punctuation, whitespace or html tags, otherwise returns the argument unchanged
  16. getLang returns the MediaWiki language code or the full language name of the current content
  17. getItemLangCode looks for country (P17), then for that country's official language (P37), and returns its language code (P424)
  18. findLanguage returns (1) supplied language if valid; or (2) the user's set language; or (3) the language of the current wiki
  19. 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
  20. 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)
  21. getGlobe returns the entity-ID of the globe used in P625 (coordinate location), or nil if there isn't one
  22. 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
  23. siteID returns the root of the globalSiteID, e.g. "en" for "enwiki", "enwikisource", "en-gb", etc.
  24. projID same as siteID
  25. location scans from the current location upwards along the chain of higher-level locations, returning each one until it reaches a country
  26. examine returns a formatted dump of the given property
  27. url2 takes a parameter that is a proper url and formats it for use in an infobox; it accepts its own output as input
  28. getWebsite fetches the Official website (P856) and formats it for use in an infobox
  29. checkvalue looks through a property for a given entity-ID as its value and returns that entity-ID if found; otherwise nil
  30. checkValidity returns whether the first unnamed parameter represents a valid entity-id
  31. showNoLinks displays the article titles that should not be linked

Function getValue

Parameters to getValue

NameAliasFunctionDefault
(first unnamed)1The property-ID whose values are returned. Required.
(second unnamed)2A locally supplied value that, if it is not empty, will be returned in preference to the value on Wikidata.empty
qidThe 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
eidAn alternative to qid. Except for eid, all parameters to getValue treat nil and the empty string the same. So, setting gives the same result as omitting the parameter. However, to provide some compatibility with other modules, using 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
qualA 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 and with a date separator.none
qualsonlyqoA 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
fetchwikidatafwdList of fields to fetch values from. ALL fetches all fields. A value of NONE or blank or omitting the parameter fetches no fields.none
suppressfieldsspfList of fields which will never display. This will even force a local value in the field not to display.none
nameName 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
onlysourcedosdA 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
dfDate format: may be dmy (day before month) or mdy (month before day) or y (year alone).dmy
qdfDate format of qualifiers. If omitted, defaults to parameter df, or "y" if df is also omitted.value of df or "y"
bcFormat of the BC/BCE suffix for dates.BCE
plaindatepdString 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
linkedA 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
displaytextdtA string that overrides the displayed text of a linked item if it is non-empty.empty
shortnamesnA 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
uselabeluselblA 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
wdlinkswdlA 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
unitabbruabbrA boolean that enables unit abbreviations for common units. Values no, false and 0 are all false; anything else is true.false
convertconvA boolean that enables passing of quantities to Template:Cvt. Values no, false and 0 are all false; anything else is true.false
showunitssuA boolean that enables showing units for quantities. Values no, false and 0 are all false; anything else is true.true
scaleA string that sets scaling for format of quantities. Values are: "a"=automatic; "0"=no scaling; "3"=thousand; "6"=million; "9"=billion; "12"=trillion.0
maxvalsSets 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)
collapseSets 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)
linkprefixlpA 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
linkpostfixA 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
prefixA 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
postfixA 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
qlinkprefixqlpQualifier link prefix (see linkprefix).empty
qlinkpostfixQualifier link postfix (see linkpostfix).empty
qprefixQualifier prefix (see prefix).empty
qpostfixQualifier postfix (see postfix).empty
sortedA boolean which enables sorting of the values returned. Values no, false and 0 are all false; anything else is true.false
qsortedA 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
noiconA 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
listThe 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
sepCustomises 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).", "
qsepCustomises 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).", "
formatDetermines 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
showDetermines 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, 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
langAllows 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
parametersetpsConvenience 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.
linkredirBoolean 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

Whitelist and blacklist

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 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 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 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 is recommended for readability).

Following a discussion at, 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 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 that may take the values "BC", or "BCE" - default is "BCE". Some test cases are shown at .

Ranks

The 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. 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:

  1. 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.
  2. Items that represent dates. These may be centuries, years, years and months, or years, months and days.
  3. Items that represent Commons media, urls, external ids, or other sorts of plain text.
  4. Items that represent quantities. All of these may have an associated unit, or be dimensionless, and may have a range.
  5. 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:

If you don't supply at least one of or, then just and are used. For example, when getting the in :

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

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 in we can make the links:

The parameters,,, are also applied to wikibase-items if they are linked.
