Sometimes interwiki links like [[Wikipedia:fr:France]] are used. This could be problematic when we start outputting hreflang on interwiki links. [[Wikipedia:fr:France]] would end up with a hreflang="en" instead of the correct hreflang="fr". Additionally it would be much nicer to have direct hrefs. Besides looking saner when the user hovers over the link it would also play much nicer with the browser's :visited handling. And it's not that unreasonable for someone to suggest "We should have a sitename in the title/tooltip". In which case [[Wikipedia:fr:France]] becomes "fr:France - Wikipedia" instead of the "France - Wikipédia" that we want. ---- Basically this means that after we've parsed out our interwiki we should consider parsing out interwikis that other wikis use. I manage to come up with an idea how this could be done for non-local wikis. We handle this in multiple passes. - The first time we see [[Wikipedia:fr:France]] when parsing an article we end up outputting it the same way we do now as (Wikipedia, fr:France) - Because an interwiki for a site we don't know any information about was used a job is queued after parsing - In the job we do an API fetch to the other wiki to get site info and the wiki's local interwiki map and we store this info - After this info is fetched we do refreshlinks jobs on the page(s) where interwiki links to this wiki was used - This second time around when parsing now that we've stored the interwiki map we parse [[Wikipedia:fr:France]] as (Wikipedia:fr, France) now that we know that Wikipedia: has a fr: inside of it's local interwiki map. This is the way it would work for remote wikis. We might do the code for this a little more abstractly. So that local cases that only require a sql lookup can be handled. And so that cases like Wikia's custom [[w:c:foo:Bar]] can also be handled by them implementing some extra code.
