ᥗᥦᥛᥰ ᥙᥣ ᥘᥥᥐᥳ:Formatter link/doc

Wikidata contains many examples of "External identifiers" such as ATC code (P267) – see Anatomical Therapeutic Chemical Classification System.

These codes are used with formatter URL (P1630) such as http://www.whocc.no/atc_ddd_index/?code=$1 where the $1 is to be substituted by the ATC code.

This template takes an external identifier code as |code= and uses a formatter url as |url= to construct a link to the external resource; an optional |label= parameter sets the text of the link, defaulting to the value of |code= otherwise.

Supplying the code as a parameter to this template allows one call to be made to Wikidata to fetch the code.

For aluminium acetoacetate (Q26979), ATC code (P267):

• {{Formatter link |url=http://www.whocc.no/atc_ddd_index/?code=$1 |code={{wdib |P267 |qid=Q26979 |fwd=ALL |osd=n |noicon=y |maxvals=1}} }} →

The formatter url to use for ATC code (P267) can be found from:

• {{wdib |P1630 |qid=P267 |fwd=ALL |osd=n}} →

In infoboxes, it will generally be hard-coded because it is specific to the infobox field. Otherwise the following can be used if Wikidata changes of the formatter url should be tracked:

• {{Formatter link |url={{wdib |P1630 |qid=P267 |fwd=ALL |osd=n |noicon=y}} |code={{wdib |P267 |qid=Q26979 |fwd=ALL |osd=n |noicon=y |maxvals=1}} }}
