The common term used to define the developer community around Sun Microsystems‘ open source project for the Solaris operating system. The term OpenSolaris refers not only to the operating system but also to the source base and developer community as well. The OpenSolaris project included source for the kernel, networking, libraries, and commands from Sun’s Solaris operating system. OpenSolaris contributions are released under the Common Development and Distribution License (CDDL), an Open Source Initiative (OSI) approved open source license.
Oracle discontinued open development and replaced the OpenSolaris distribution model with the proprietary Solaris Express in in 2010. See also Solaris for a better understanding of this term.
