property = Wikidata property number, without the prefix P.
section = section number to place the identifier. See #List of sections for details.
pattern =Lua pattern of valid format for identifier. Note this is similar but not identical to a regular expression. If this is omitted, then the module will not check the validity of the identifiers.
link = the URL of the external page with details of the identifier. The code $1 will be replaced with the identifier.
label = the label for the link.
remark = a brief explanation of the authority control database, for use on the documentation of Template:Authority control only.
The syntax below generates a link to the Dictionary of Irish Biography in section 5. It gets its data from Wikidata property (P6829) and identifiers need to be in the following form: 0, followed by 0 or 1, followed by 4 digits, possibly followed by a decimal point and then a letter from A to D.
patterns = if more than one Lua pattern is needed, then use the plural form of this argument and include the comma-separated list of patterns enclosed by curly braces.
prefix = a prefix to be included before the links. In this case numbers 1, 2, ... will be used as the labels and the label field will be ignored.
valid = the name of a custom Lua function in /auxiliary used to determine if the identifier is valid or not, in case the pattern method cannot be used. It should return false if the identifier is invalid.
customlink = the name of a custom Lua function in /auxiliary which will produce the entire external link. It should return false if the identifier is invalid.
suppressedbyproperty = if this identifier should not be displayed if other identifiers are present, then specify them here in a comma-separated list enclosed by curley braces.
