GPL 3 debate begins in earnest
Published: 17 Jan 2006 09:50 GMT
The Free Software Foundation on Monday released the first public discussion draft of the GPL version three, shedding light on proposed reforms to the document's patent and digital rights management provisions.
The GPL 3 draft can be downloaded from the FSF's Web site, which also includes an explanation of the changes and an online commentary section. The revised GPL is the subject of a conference this week at the Massachusetts Institute of Technology.
The foundation is revising the GPL for the first time in 15 years, and this time the organisation is accepting suggestions from the broad base of people and organisations now involved in the free software and open source software movements. Over the last decade and a half, the GPL grew from an academic curiosity created by programmer and FSF founder Richard Stallman into a critical foundation of much of the software realm.
The GPL governs countless open source projects, including the Linux kernel, the Samba file server software and the MySQL database. "It's tremendously important," Tom Carey, an intellectual-property attorney at Bromberg & Sunstein, said in an earlier interview. "Probably most lawyers who have an active practice in the software area have read the GPL and committed its essence to memory, which is something you can't say about any other licence."
The proposed GPL revisions include changes in several expected areas:
• Provisions to make sure digital rights management mechanisms don't curtail software freedoms;
• An explicit grant of patent rights by anyone redistributing GPL-governed software;
• A retaliation clause that prohibits an organisation from using privately modified GPL software if it files a patent infringement lawsuit relating to that software.
• And new terms describing how copyright holders may add additional licensing terms, such as more severe patent retaliation provisions, to GPL software.
Regarding the new patent provisions, Aberdeen Group analyst Stacey Quandt said, "GPL 3 is an improvement over its predecessor." But she also predicted the issue is likely to spark debate. In addition, in the GPL 3 draft, it's "not necessarily clear what constitutes a derivative work", a central concept that describes modified versions of a program, she said.
The FSF hopes to complete GPL 3 by 15 January, 2007, but is giving itself until March 2007. A second discussion draft is planned to be released June, with a possible third in October.
GPL-governed software is widely used in the technology industry. However, there are many other open source licences in use. Sun, for example, is touting its Community Development and Distribution License as an alternative.
