### Problem statement There are various use cases in core and extensions not directly related to URL-shortening. Cases where one want to show urls to users that should take advantage of URL shortening. There should be a core service to support this transformation, where you can pass in an URL (or maybe a Title object and an array of query parameters) and get back another URL which resolves to the same address but if possible is shorter. ### Proposal The default behavior in MediaWiki core could be to just return the URL unchanged, or maybe to use `curid` instead of `title` page name (that changes the semantics though as page name and page id are not inseparably linked together). The non-default behavior could be implemented by an extension like UrlShortener. One complication is that shortening a URL that wasn't shortened before requires a DB write, which should be avoided on GET requests. See also: * `File::getDescriptionShortUrl()`

Another is that it should work with cross-DB titles (as the main use case is Commons file description pages). See also: * `File::getDescriptionShortUrl()`
