Hewlett-Packard kicked the first open source component to WebOS out the door today, along with a calendar for when its source code will be completely open.
The first part of WebOS to go open is Enyo, which also received a version bump to 2.0 today. Enyo is a developer's tool for writing a single app that will work across multiple mobile devices and PC browsers, including Firefox, Internet Explorer, Chrome, iOS, Android, and WebOS itself.
HP added that all WebOS code will be released under the Apache license.
As my colleague Roger Cheng noted in December when the company announced its decision to open WebOS, with the exception of Linux, the most successful open-source projects receive great scads of cash. What HP didn't reveal was how much backing the struggling operating system will continue to receive.
