It is important that whatever the UI language is, only one URL linked to the document. If we don't do that we will have the following problems: - users will have trouble to link to our content as what is seen will depend not of the viewer choice but of the linker choice (I will see the interface in polish if the link has been done by a polish guy) - It will create numerous duplicate pages in search engines. (Which may even lead us to be flagged as "Duplicate content" web site and being unindexed) - Link juice for SEO will be split into the different pages. We need to have this as a user facing urls: https://developer.mozilla.org/docs/en-US/<name_of_the_page> and not https://developer.mozilla.org/fr/docs/en-US/<name_of_the_page> https://developer.mozilla.org/en-US/docs/en-US/<name_of_the_page> https://developer.mozilla.org/it/docs/en-US/<name_of_the_page> https://developer.mozilla.org/es/docs/en-US/<name_of_the_page> https://developer.mozilla.org/pt-BR/docs/en-US/<name_of_the_page> ... The language of the chrome UI of the page must be selected using Accept-Language:, eventually overriden by a profile parameter (if logged).
And of course we need to have 3xx Permanent redirect from the old pages to the new ones.
Could be complicated - all of our other sites use the "site language prefix" part of the url. CC'ing James Socol who has done much of the SUMO locale prefix work that we're using.
So, from a broader perspective... Nearly all Mozilla sites (and those that don't have a good reason) right now use the locale in the URL as a prefix. whatever.mozilla.org/%LOCALE%/content So we should really stick to that convention. What we have here is an extremely unique requirement: no other Mozilla site (in fact very few other sites I know of at all) asks for "content" and "UI" in different languages. Kitsune, from which Kuma was forked, will occasionally show English document content with a localized URL (where the locale for the UI is dependent on the URL) when there _is_ no localized content. For SUMO, which is in a less competitive SEO space, that's fine. In response to comment zero, I'll say: 1) It should be developer.m.o/%LOCALE%/docs/%PAGE%, not /docs/%LOCALE%/page, for consistency with all other Mozilla sites. 2) MDN is in a competitive SEO space, but in cases where we show English (or any other Locale's) content with a different UI language, something like <link rel="canonical"> should be able to help solve that. 3) I do not agree with the final comment "The language of the chrome UI of the page must be selected using Accept-Language:, eventually overriden by a profile parameter (if logged)." W/r/t (3), the URL should be the winner. A URL should give you a single resource, linkable to anyone. Now, part of that may need to be contained in a query string. I don't fully understand the use-case for splitting UI locale and content locale, but 1) the path shouldn't contain both, that's silly, bad for SEO, and silly, 2) the path should contain the locale of the intended content, 3) if the split is necessary, can we push part of that into a query string or cookie, instead of the URL?
I was leaning towards a query string halfway into reading your comment. So: d.m.o/%LOCALE%/docs/%PAGE%?site_language=%LOCALE% e.g., d.m.o/fr/docs/HTML/HTML5?site_language=en-US That way d.m.o/fr/docs/HTML/HTML5 always means "The French article for HTML on MDN"
> 3) I do not agree with the final comment "The language of the chrome UI of > the page must be selected using Accept-Language:, eventually overriden by a > profile parameter (if logged)." That's the only correct way to do it. That's the goal of the Accept-Language. That's not the person who makes the link who decide it, but the one who access it.

That's the goal of the Accept-Language. That is not how Mozilla sites do it. This decision has its reasons and we should stick to it for those reasons and consistency with all other Mozilla web properties. > That's not the person who makes the link who decide it, but the one who > access it. One URL should be one resource, not different resources for different people. MDN is not enough of an "app" for that. I think we'd agree that the resource here is the page content, not the site UI.
Why can't the user simply have a preference that lets them pick their UI language? Default to showing the same UI language as the page if they haven't set a preference. This seems the most reasonable solution to me, and is what I would prefer. Then you don't need to do weird stuff with the URL, query strings, etc. We need user preferences anyway.
(In reply to James Socol [:jsocol, :james] from comment #6) > This decision has its reasons Sorry James, I find this answer rude and not acceptable. I'm not stupid: I can understand reasons. I think we are loosing time here. We should revert the ability to have a chrome of the page in the different language than the content. It is not perfect, but it is better than what we have know which is a no-go for Kuma. We can leave with the same language for chrome and content for Kuma launch, even if it is annoying when we want to edit a Chinese page because of vandalism. We can discuss reintroduction separation of language for UI and chrome in Q3 or Q4.

Thanks James, even I knew that it wasn't your intention, but it got me heated anyway. I will look at this bug again tomorrow, once I will have really cooled down :-) New day, new eyes, new ideas, new opinions.

Also, just for some more input to the topic: http://restpatterns.org/Articles/Designing_URIs
I'm neck-deep in this right now for bug 728417. I'm restoring lots of the translation features we inherited from kitsune/SUMO. I agree we should show the same single language for both site UI and doc content. I propose we go with the Accept-Language and URI segments as kitsune/SUMO: /%LOCALE%/docs/%SLUG% E.g., /fr/docs/AJAX /en-US/docs/AJAX /es/docs/HTML/HTML5 The kitsune/SUMO locale-detection code first uses Accept-Language header AND allows that language selection to be overridden via direct url. E.g., GET /docs/AJAX Accept-Language: fr, en;q=0.8 HTTP/1.1 301 MOVED PERMANENTLY Location: /fr/docs/AJAX Vary: Accept-Language GET /en-US/docs/AJAX Accept-Language: fr, en;q=0.8 HTTP/1.1 200 OK Later we can decide if/when we need the ability to show site UI and content in separate languages. Sound good?
Luke, that's ok for me, but: all internal links in Kuma must be of the form /%LOCALE%/docs/%SLUG% . We should never have /docs/%slug% in it (or locale-detection override user choice and it renders the Web site unusable)
Sounds good to me.
Links to /docs/%slug% go thru this locale-detection logic: https://github.com/groovecoder/kuma/blob/page-translation-features-bug-728417/apps/sumo/urlresolvers.py#L94-123 i.e., ?lang or the most appropriate and relevant Accept-Language is used, if we support the language. Lastly, we default to en-US. So, the only way the user *chooses* their language is by the ?lang parameter (using the language drop-down in the header or footer of the site) or by Accept-Language header value. We have a "Language" drop-down in the user profile, but we don't use it to determine language (yet).
Sorry, all that is to say links to docs/%slug% seem good to me - i.e., link to a doc and let the site determine the best language based on that logic.
You seem to assume that content in all languages is equal. That's not the case. In my strong opinion, the canonical URL of a page should include the language, and the wiki-internal links should link directly to the canonical URL.
What is this attribute lang? We never spoke about that. We need to have the locale of the page in the URL. We want people to link to a specific locale of the page and when I'm navigating I want to be sure to stay on the same locale, except if I explicitly choose another locale. That's what is done now and must not be changed. If the page I'm navigating to doesn't exist in the locale I'm requesting, we want to have an "Article not found" page (that is a 404 page) with the ability to create it. URL without locale in them must redirect to a page with a locale in the URL, the way the locale is chosen in that case is either Accept-language either the lang parameter. URL with locale in them must ignore the lang parameter for the content language. Internal links in the wiki must always link to URL with locale.
:teoli - sounds perfect, with on caveat: django middleware uses the ?lang= parameter to *switch* languages. E.g., if you go to /fr/HTML/HTML5?lang=en-US it redirects to /en-US/HTML/HTML5 We don't want to change that - we use it all over the rest of MDN and other Mozilla websites. It's how users "explicitly choose another locale" - it's an explicit signal to the middleware that the user is intentionally changing language, so we can do things like set a language preference cookie. In reality, there are never links to ?lang= url's. It's only used internally by the language selector menu in the footer of the site.
(In reply to Luke Crouch [:groovecoder] from comment #20) > django middleware uses the ?lang= parameter to *switch* languages. E.g., if > you go to /fr/HTML/HTML5?lang=en-US it redirects to /en-US/HTML/HTML5 I have no problem with that :-) That's ok.
Time to do this is pre-July, if ever.
