Help:Magic links

Magic links are a feature of MediaWiki core that create automatic links for 3 hardcoded external identifiers.

As of MediaWiki 1.28, this feature is disabled by default but may be enabled using the  configuration parameter.

Examples:


 * -> ISBN 0-7475-3269-9
 * -> PMID 1234
 * -> RFC 1234

ISBN is hardcoded to link to Special:Booksources, while the URLs for PMID and RFC can be changed by editing the help>Special:MyLanguage/Help:System message|system messages   and  , respectively.

Alternatives
Because magic links are hardcoded and inflexible, you can also use more straightforward interwiki or links:


 * -> RFC 1234
 * -> PMID 1234
 * -> ISBN 0-7475-3269-9

Creating a local template similar to w:Template:ISBN, v:Template:RFC, or v:Template:PMID may be useful.
