The '''Sun Industry Standards Source License''' ('''SISSL''') is now a retired [[free software|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 (programmer)|Simon Phipps]] announced the retirement of the license on September 2, 2005 to combat [[license proliferation]].<ref>[http://blogs.oracle.com/webmink/entry/addressing_proliferation_deeds_not_just Addressing Proliferation: Deeds not just Words]</ref> 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."<ref>{{cite web|url=http://www.opensource.org/licenses/sisslpl.php|title=Sun Industry Standards Source License (SISSL)|publisher=Open Source Initiative|accessdate=2008-05-20|archiveurl=https://web.archive.org/web/20130113054628/http://opensource.org/licenses/sisslpl.php|archivedate=2013-01-13}}</ref><ref>{{cite web|url=http://www.opensource.org/licenses/category|title=Open Source Licenses by Category|publisher=Open Source Initiative|accessdate=2008-05-20}}</ref>  OpenOffice.org 2.0 code, for example, is now licensed exclusively under the LGPL. Sun developed the [[Common Development and Distribution License]], a variant of the [[Mozilla Public License]] and later released [[OpenSolaris]] and the [[GlassFish]] Application Server under that license.
