Sun Industry Standards Source License
Encyclopedia
The Sun Industry Standards Source License (SISSL) is now a retired free
and open source
license, recognized as such by the Free Software Foundation
and the Open Source Initiative
(OSI). Under SISSL, developers could modify and distribute source code and derived binaries freely. Furthermore, developers could choose to keep their modifications private or make them public. However, the SISSL is unique among OSI-approved licenses in requiring that "The Modifications which You create must comply with all requirements set out by the Standards body in effect one hundred twenty (120) days before You ship the Contributor Version." If the Modifications do not comply, SISSL becomes a copyleft license, and source must be published "under the same terms as this license [SISSL] on a royalty free basis within thirty (30) days."
Several open source projects funded by Sun Microsystems
were licensed under SISSL, including OpenOffice.org
, and Sun Grid Engine
(SGE). Later versions of OpenOffice.org were dual-licensed under the SISSL and LGPL until the retirement of the SISSL, at which time OpenOffice.org was relicensed only under the LGPL. Sun Grid Engine appears to still be covered by the SISSL.
Sun's Chief Open Source Officer Simon Phipps
announced the retirement of the license on September 2, 2005. It is now listed by OSI as "voluntarily retired" by Sun, and the OSI license page states that "Sun has ceased to use or recommend this license." OpenOffice.org 2.0 code, for example, is now licensed exclusively under the LGPL. Sun has developed the Common Development and Distribution License
, a variant of the Mozilla Public License
and has since released OpenSolaris
and the GlassFish
Application Server under that license.
