Microsoft, Opera, Google, Facebook, Mozilla, Nokia, Adobe, and W3C have collaborated together on a project named WebPlatform.org.

The idea is to collect all the information currently spread across their own development sections related to web development at a centralized location.

The project itself is open to anyone who wants to contribute as it also has a wiki powered database.

The project developers said in a blog post:

WebPlatform.org will have accurate, up-to-date, comprehensive references and tutorials for every part of client-side development and design, with quirks and bugs revealed and explained. It will have in-depth indicators of browser support and interoperability, with links to tests for specific features. It will feature discussions and script libraries for cutting-edge features at various states of implementation or standardization, with the opportunity to give feedback into the process before the features are locked down. It will have features to let you experiment with and share code snippets, examples, and solutions. It will have an API to access the structured information for easy reuse. It will have resources for teachers to help them train their students with critical skills. It will have information you just can’t get anywhere else, and it will have it all in one place. But it doesn’t. Not yet. Right now, it has a wiki, docs.webplatform.org, which anyone with an account can edit, and structured templates for ensuring consistency. It has a massive import of data from Microsoft, Opera, Google, Facebook, Mozilla, Nokia, Adobe, and W3C, still in a rough form, that needs a lot of polishing. It has a chat channel and Q&A forums, and a blog. And all this material will be available free, for anyone to use for any purpose.
