Module:Edition

The Edition module is responsible for retrieving and displaying various bits of data about editions on Wikisource.

For all of the methods below, the wikidata parameter can be left out and the item ID of the page on which it is invoked will be used.

Method: author_list

Get a list of authors. These will be linked to their author pages where they exist.

Used by {{author-list}}.

Wikitext	Output
{{#invoke:Edition|author_list|wikidata=Q28913867}}

Method: badge

Display Wikidata badges for an edition.

Edition	Wikitext	Output
A Camp in the Adirondacks	{{#invoke:Edition|badge|wikidata=Q16325556}}
The Great Secret	{{#invoke:Edition|badge|wikidata=Q75047127}}
The Riverside song book/The Open Window	{{#invoke:Edition|badge|wikidata=Q59364480}}
Douglas Adams (no badge)	{{#invoke:Edition|badge|wikidata=Q42}}

Method: inline

The 'inline summary' of an edition can be used on an author's page, for example, to show the basic details about the edition and work.

Wikitext	Output
{{#invoke:Edition|inline|wikidata_id=Q28913867}}

Method: authority_control

For editions, you can list all available authority controlled identifiers with:

Wikitext	Output
{{#invoke:Edition|authority_control|wikidata=Q28020002}}

And if you want to list all for the parent work of the edition, use:

Wikitext	Output
{{#invoke:Edition|authority_control|wikidata=Q28020002|show_work=yes}}
