710733 - Implement breadcrumbs for page hierarchy navigation

Status: RESOLVED FIXED

(developer.mozilla.org Graveyard :: Editing, defect, P2)

Description

[Les Orchard [:lorchard]]

MindTouch supports breadcrumbs for navigation between sections of page hierarchy. Kuma should probably support this, though we may also need to revise page models to accommodate breadcrumbs and hierarchy

More thoughts: This might go beyond just breadcrumbs in the web UI. Mindtouch actually supports page hierarchy with paths in the slug/title. 

We should support that and consider what that implies. ie. Access control to edit pages below a given path? Moving a whole section of pages? what else?

There should be a link between the breadcrumbs and the <title> of the page.

Example: 

The page en/CSS/pointer-events should have a breadcrumbs:
MDN > Cascading Style Sheets (CSS) > pointer-events

and its (default) <title> should be:
pointer-events — CSS — MDN

This would help in cases of synonyms (title displayed as tab name) and for SEO, too.

That confuses me - the titles and url slugs are up to the authors. It seems we could implement a minimum-viable-breadcrumbs feature by splitting on '/' characters in the slug and linking to each token? That could cover all the migrated content until we decide to build out better page hierarchy, yes?

[Jean-Yves Perrier [:teoli]]

Currently (DekiWiki) the page name (<H1>) and title (<title>) are synchronous (with - MDN appended to the title). 

This prevents us to make user-friendly title, which allows to differentiate Time - Javascript - MDN and Time - HTML - MDN in a tab bar. (Worse, the current situation is bad as some people adapt the H1 to have a search-engine-friendly title).

If these two entities are no more synchronized in Kuma, it is a good thing. But this creates a new problem: I don't want to go to all Javascript/HTML/XUL/CSS/... pages to manually edit the titles to something sensible. More I don't want to do this for each and every new created page (as most contributors don't care about such details), so we need a sensible default. And to populate, by default, the <title> with a part of the hierarchical structure, *like the breadcrumbs but in a reverse order*, is a possible solution.

Maybe it should be a different bug...

Bumping to 2.7 - let's discuss this at MDNYC.

Would prefer not to use page title to define hierarchy

Currently the parent/child relationship is used for translation (English version = parent) so this would have to be addressed.

break into 4 subbugs: 
1. implement page hierarchy in kuma (parent doc field in kuma)- add parent field.
2. migrate the relationship from MindTouch
3. draw breadcrumbs from that relationship
4. build UI to manage the relationships (set parent for this page, create child for this page)

turn this into tracking bug

All blockers of this bug are closed... I think we're good for breadcrumbs as a feature, for now? File additional blockers of bug 756263, if there are must-have additions or things broken for pre-July
