Hoping to create the definitive resource for all open Web technologies, Apple, Adobe, Facebook, Google, HP, Microsoft, Mozilla, Nokia, and Opera have joined the W3C to launch a new website called Web Platform. The new website, which just launched into alpha, will serve a a single source of relevant, up-to-date and quality information on the latest HTML5, CSS3, and other Web standards, offering tips on web development and best practises for the technologies. According to the W3C, the website will also display the status of a particular technology’s standardisation and cross-browser implementation. The site is also a wiki that allows users to ask, answer and rate questions similar to Stack Overflow, which seems the closes competitor. Originally, the site was open to just employees of the sponsor, but it seems to have opened to all registered users now. All documents posted to the Web Platform website are licensed under creative commons. While the initial content was provided by the member companies, website visitors are encouraged to share code examples, tips and tricks or any other relevant information using the Wiki. Building and maintaining interoperable systems on the web is a community effort and one that we at ExtensionEngine participate in on a daily basis. We look forward to engaging on Webplatform.org and contributing to ensure a bright, interoperable future!
