Today, HP gave the first details regarding the now open source webOS mobile platform, cleverly dubbed "Open webOS 1.0." The company released Enyo, its JavaScript app framework, under an open source license, allowing developers to port their apps to other mobile platforms. 

This initial open source release includes Enyo 1.0, which allows current developers of Enyo apps for webOS devices to distribute their apps to other platforms. While this release is not intended to be expanded any further, there is considerable utility for our current developer base in releasing it.

Today’s release also includes the core of Enyo 2.0, which will be the foundation for Enyo going forward. It expands Enyo’s “write once, run anywhere” capability to even more platforms, from mobile devices to desktop web browsers. It works on many of the most popular web browsers, including Chrome, IE 9, Firefox, and Safari.

HP says that the current release of version 2.0 doesn't include UI widgets, but a future release will. In addition, the company notes that a future release will include a version of WebKit, a platform that web browsers are based from, with support for HTML5, Silverlight, Flash, 3D textures and multi-touch. 

More information is available at the official Enyo website.

HP announced last month that it plans to keep webOS, which was killed in August 2011, around as open source development.
