Using GPL differently: WordPress and MovableType Open Source
September 16th, 2007 by John EckmanEarlier this summer, the folks at Six Apart announced the formation of an open source project around the Movable Type blogging platform (see my post on OpenParenthesis and Sebastian’s on blog.wohlrapp.com).
There’s been a fair amount of anticipation surrounding the project, since Movable Type was an early an important platform for users hosting their own blogs, and it seemed that a GPL’d version of that platform would be a potentially strong competitor to WordPress and Roller for anyone interested in an open source blog platform. (The launch date for the OpenSource version is still said to be Q3 of 2007 - which ought to be quite soon).
Recently, Mark on WordPress (”What a GPL’d Movable Type Means for WordPress“) pointed out a key difference between WordPress and MTOS (and not just that Movable Type is two words while WordPress is just one, though that seems hard enough for me to remember - you’d think the fact that the company name is Six Apart should be enough to remind me).
Although both WordPress and MTOS are/will be released under the GPL (v2 presumably, though Six Apart hasn’t said for certain), Six Apart’s Open Source Contribution Policy will require contributors to assign copyright to Six Apart for anything they contribute, in order to preserve their ability to dual license the application.
