Template talk:Iw
From Mass Spec Terms
https://www.mediawiki.org/wiki/Manual:Interwiki
As an alternative to interwiki linking, a template can be created to wrap a plaintext page title into a URL-encoded external link to a known wiki, which can then be called with syntax equivalent to interwiki links.
This preserves the appearance of external links while providing the same convenience as interwiki linking.
<!-- Template:IW --> [https://example.com/wiki/{{urlencode:{{{1}}}|WIKI}} {{{2|{{{1}}}}}}]
Then, instead of [[iw:External Page Title]], call the template:
{{IW|External Page Title}}→ External Page Title{{IW|External Page Title|Alternate text}}→ Alternate text
