Документација модула[прикажи] [уреди] [историја] [освежи]

This модул is intended to fetch data from Wikidata with or without a link to the connected Wikipedia article.

Usage[уреди извор]

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

Commands[уреди извор]

Value class[уреди извор]

The value class commands can be combined, meaning that multiple commands of different types from this class can be given at one time.

Combine multiple commands into one call to this модул instead of making multiple calls to this модул with one command each to be sure that all the returned pieces of information belong to each other.

Type Command Returns Basic usage Description
1 property first match* {{#invoke:wd|property|P1}} Returns the requested property – or list of properties – from the current item, or a given item.
properties all matches {{#invoke:wd|properties|P1}}
2 qualifier first match* {{#invoke:wd|qualifier|P1|P2}} Returns the requested qualifier – or list of qualifiers – from the given property of the current item, or a given item.

Unlike the other value-class commands, this command can be given multiple times to retrieve different qualifiers in one call.

qualifiers all matches {{#invoke:wd|qualifiers|P1|P2}}
3 reference first match* {{#invoke:wd|reference|P1}} Returns a reference – or list of references – from the given property of the current item, or a given item.
references all matches {{#invoke:wd|references|P1}}
* Returns only a single value instead of multiple (if multiple claims or statements match). The returned value is the first match found from the best-ranked claims.

Name class[уреди извор]

The name class commands cannot be combined.

Command Basic usage Description
label {{#invoke:wd|label}} Returns the label of the current item, or a given item or property. In case of an item that has no label, the title of the linked page will be returned instead if it exists.
title {{#invoke:wd|title}} Returns the title of the page linked to the current item, or a given item, if such page exists. The label of the item will never be returned instead.

Main class

Command Basic usage Description
main {{#invoke:wd|main|command|P1}} Intended for use by a wrapper template (around this module) to invoke one of the above commands, returning their respective output.

The parameters passed to the wrapper template are the ones that will be used by the module, e.g. {{wikidata|property|P1549}}{{#invoke:Wd|main}}{{#invoke:Wd|main|property|P1549}}.

Therefore, any parameters set by the wrapper template itself will be discarded, e.g. {{wikidata|property|P1549}}{{#invoke:Wd|main|qualifier|P1082|P585}}{{#invoke:Wd|main|property|P1549}}.

Flags[уреди извор]

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

Command flags[уреди извор]

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

Flag Description
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 Gets the short name (P1813) of any item returned if they have one attached. If that is not the case, then the default behaviour of returning the item label will occur.
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.

For quantity datatypes, this flag will strip off any units of measurement.

If this flag is used with time datatypes, then the returned date will be in the format of year-month-day (e.g. 1731-2-11). Dates in the Julian calendar stored with a precision of days through millenniums will have /Julian attached to the output (e.g. 1731-2-11/Julian, which may be split off using the {{#titleparts}} template 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}} template function).

Configuration flags[уреди извор]

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

Flag Description
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).

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).

current
former
mdy Returns date values in month_day_year order instead of day_month_year order.

Arguments[уреди извор]

The following table shows the available arguments (arg*) in their fixed order. For each command, the minimal set of arguments is marked (i.e. 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 qualifier_id arguments are given.

(required) (optional) (optional) (required) (optional) (required) (required)
{{#invoke:wd commands flags item_id property_id claim_id_or_lit_value qualifier_id qualifier_id }}
label, title
property/properties
reference/references
qualifier/qualifiers
qualifier/qualifiers (optional 2nd, 3rd, etc.)

Below follows a description of all arguments.

Argument Description
item_id

(optional)

EXPENSIVE Q-identifier of the item to be accessed (e.g. Q55).

In case of the label command, a P-identifier (or an available alias) of a property (e.g. P38) can also be given.

If this parameter is omitted, then the item connected to the current page will be used.

property_id P-identifier or an available alias of the property to be accessed (e.g. P38).
claim_id_or_lit_value

(optional)

Either the Q-identifier equal to the property value of the particular claim to be accessed (e.g. Q6655) or a literal value (i.e. string or quantity etc., no item label) equal to the property value (in its raw form) of the claim to be accessed.

Dates as literal values must be formatted year-month-day (e.g. 1731-2-11) for dates with a precision of days, year-month (e.g. 1731-2) for dates with a precision of months, and year (e.g. 1731) for dates of lesser precision without any spaces or leading zeros. Dates BCE require a minus sign in front of the year (e.g. -2950-1-31). Dates stored in the Julian calendar must have /Julian attached to the end (e.g. 1731-2-11/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 space (i.e. ||).

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 to be accessed (e.g. P518).

Named properties[уреди извор]

Named properties are aliases for P-identifiers. The following named properties (which are case-sensitive) are currently available:

Advanced usage[уреди извор]

The layout of the output from value class commands can be customized by using a number of named flags, which are name-value pairs (i.e. |flag=value). The table below shows the available named flags.

Named flags can be given anywhere after the first command. To insert a space at the beginning or end of a value, use the HTML entity  .

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.
%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 (if a list of claims is returned). This is handy in case a 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.

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. \%).

%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:smaller">(%q)</span>][%s][%r] if the property/properties command was given and the qualifier/qualifiers command was given
sep= &#32; default The fixed separator between each pair of claims.
if only the reference/references command was given without the raw flag
sep%s= , default The movable separator between each pair of claims. This will be the value of the %s parameter applied to all claims except for the last in the list.
; if the property/properties command was not given and the qualifier/qualifiers command was given
sep%q1=, sep%q2=, sep%q3=, ... ,&#32; 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= ,&#32; 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.

;&#32; 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.
&#32; 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 in the list.

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