Module:External links

| File:Ambox warning yellow.svg | This Lua module is used on approximately 60,000 pages and changes may be widely noticed. Test changes in the module's /sandbox or /testcases subpages, or in your own module sandbox. Consider discussing changes on the talk page before implementing them. |
| File:Full-protection-shackle.svg | This module is subject to page protection. It is a highly visible module in use by a very large number of pages, or is substituted very frequently. Because vandalism or mistakes would affect many pages, and even trivial editing might cause substantial load on the servers, it is protected from editing. |
This module is designed for implementing templates to display external links in an English Wikipedia article, using the properties defined in that article's Wikidata item. It was based on the Norwegian Wikipedia module no:Modul:External links.
The first test implementation is Template:Sports links (based on no:Mal:Sportslenker). The sports-related link properties and formats are specified in Module:External links/conf/Sports (based on no:Modul:External links/conf/Sport).
Other subject-based implementations at the Norwegian Wikipedia include:
- Arts (no:Mal:Artslenker and no:Modul:External links/conf/Arter)
- Astronomy (no:Mal:Astronomilenker and no:Modul:External links/conf/Astronomi)
- Authority data (no:Mal:Autoritetsdata and no:Modul:External links/conf/Autoritetsdata)
- Film (no:Mal:Filmlenker and no:Modul:External links/conf/Film)
- Film person (no:Mal:Filmperson and no:Modul:External links/conf/Filmperson)
- Music (no:Mal:Musikklenker and no:Modul:External links/conf/Musikk)
- Official links (no:Mal:Offisielle lenker and no:Modul:External links/conf/Offisielle lenker)
- Games (no:Mal:Spill-lenker and no:Modul:External links/conf/Spill)
