Usage[edit]

[[External formatter uri::https://www.example.org/$1]]

Example[edit]

If you create a property called "Has Wikidata item ID" of datatype datatype "External identifier"Holds a value that associates it with with a external URI for formatting and specify an external formatter URI using this special property ([[External formatter uri::https://www.wikidata.org/entity/$1]]) when a value annotated to a page with e.g. [[Has Wikidata item ID::Q42406391]] will display the value "Q42406391" automatically linked to the respective Wikidata site entry like Q42406391.

Reusing interwiki prefixes[edit]

You can reuse an existing interwiki prefix with the fullurl parser function. For example:

[[External formatter uri::{{fullurl:wikipedia:$1}}]]

Multi parameters[edit]

An external canonical URL can have different parameters to represent different versions of the content as in case of Wikipedia. In order to pinpoint the version, an additional parameter is necessary. The syntax {...} supports those additional parameters.

For a property "wikipedia" with:

[[Has type::External identifier]] [[External formatter uri::https://en.wikipedia.org/w/index.php?title=$1&oldid=$2]]

You can annotate

[[wikipedia::Truid Aagesen{837787373}]]

Thus, {...} identifies aditional parameters to the external URI and SMW will create a link to:

https://en.wikipedia.org/w/index.php?title=Truid_Aagesen&oldid=837787373

You can also add a space in between "Truid Aagesen" and "{837787373}" for better readability.
