(arrghh, I forget that pastes *don't* render the Remarkup language.  Copy and paste this into a comment, edit until it looks right, then copy and paste the new version back up here.)

http://devhub.wmflabs.org is a prototype of the "Data and developer hub", a portal and set of pages whose goal is to encourage third-party developers to use Wikimedia data and APIs. Check it out. Your feedback is welcome, you can discuss in this mail thread, or [[https://phabricator.wikimedia.org/maniphest/task/create/?projects=dev.wikimedia.org | file Phabricator tickets in the project dev.wikimedia.org]].

Around the 2014 Zurich Hackathon, Moiz Syed, Juliusz Gonera, and others discussed creating "a thing" to expose our APIs and data to developers. When S Page moved to WMF tech writer, he wrote some articles for this and with Quim Gil developed a landing page from the [[ https://www.mediawiki.org/wiki/Dev.wikimedia.org#Structure | wireframes ]].

The prototype is using the Blueprint skin and running on a Wikimedia Labs instance, but the articles are all regular wiki pages on mediawiki.org.

Thanks to everyone who participated in the gestation of this idea.
S Page and Quim Gil

=== FAQ 
Q: How can I get it to feature my API?
A: [[https://phabricator.wikimedia.org/maniphest/task/create/?projects=dev.wikimedia.org,documentation | Create a task in dev.wikimedia.org and documentation]] with "Article" in the title. You can write an article yourself, see [[ https://www.mediawiki.org/wiki/dev.wikimedia.org/Contributing | dev.wikimedia.org/Contributing ]].

Q: Yet another site? Arghh!
A: Agreed, T101441 "Goal: Integrate new Developer hub with mediawiki.org". It's a separate site for now in order to present a different appearance.

Q: But why a different appearance? Why a separate skin?
Our competition for developer mindshare is sites like https://developers.google.com/. We believe looking like a 2000s wiki page is a //deterrent// to using APIs and data. We hope that many third-party developers join our communities and eventually contribute to MediaWiki, but "How to contribute to MediaWiki" [1] is not the focus, providing free open knowledge is.

Q: Why the Blueprint skin?
A: Prateek Saxena, Andrew Garrett, and May Galloway developed it for the OOUI Living Style Guide [2] and it has some nice features: a fixed header, and a sidebar that gets out of the way and combines page navigation and the TOC of the current page.

Q: So why not use the Blueprint skin on mediawiki.org?
A: Agreed, T93613 "Deploy Blueprint on mediawiki.org as optional and experimental skin" is a blocker for T101441.  We appreciate help with it and its blockers.

Q: I hate the appearance.
A: That's not a question :) Then forget the prototype exists and view the same content at https://www.mediawiki.org/wiki/API:Data_and_developer_hub

Q: Is this "dev.wikimedia.org"?
A: Sort of.  http://dev.wikimedia.org will be the well-known shortcut to the "hub" page. And dev.wikimedia.org is the project name for this "Data and developer hub".

Q: I thought dev.wikimedia.org was going to integrate generated documentation/replace doc.wikimedia.org/enumerate all Wikimedia software projects/cure cancer, what happened?
A: One step at a time.  For now, its goal is, to repeat, "to encourage third-party developers to use Wikimedia data and APIs".

Q: Why are the pages in the API: namespace?
A: That's temporary, they will probably end up in a `dev:` namespace on mediawiki.org that uses the Blueprint skin by default (T369).

Q: Where are the talk pages?
A: It's a bug that the sidebar doesn't have a "Discussion" link. The talk pages on the prototype all redirect to the talk pages on mediawiki.org, and Flow is enabled on them.
