Welcome

The SysML Forum is a web community dedicated to the Systems Modeling Language (SysML), a new visual modeling language standard for specifying systems and systems-of-systems. Here you can find information related to SysML modeling tools, specifications, tutorials, mailing lists, and blogs.

SysML customizes the UML™, the industry standard for modeling software-intensive systems, for systems engineering applications. It supports the specification, analysis, design, verification and validation of a broad range of systems and systems-of-systems. These systems may include hardware, software, information, processes, personnel, and facilities. The SysML Partners completed their SysML v. 1.0a open source specification draft and submitted it to the Object Management Group (OMG) in November 2005. A series of competing specification proposals was followed by a "SysML Merge Team" proposal submission to the OMG in April 2006, which was adopted by the OMG as OMG SysML™ in July 2006.

The most current version of the SysML open source specification is available for download by clicking here. See for yourself why this new domain specific language is smaller and better suited for systems engineering applications than the Unified Modeling Language™ (UML™) on which it is based. (SysML is currently specified as a UML 2.0 Profile, or customization.)

February 26, 2008. – Top Coder Introduces Free Open Source UML Design Tool to Developers.
TopCoder, Inc., a leader in online programming competition, skills assessment, and competitive software development, today introduced a free Unified Modeling Language (UML) design tool for the virtual and professional development communities. The Top Coder UML tool was designed, built, and tested by Top Coder's global community of developers and purports to offer a better solution for the core functionality developers typically need in a UML tool, and avoids unnecessary feature sets. The source code for the Top Coder UML tool is open for anyone to extend or enhance for their own purposes. To download TopCoder's free UML tool or to view its source code and documentation click here. For the full press release click here.

October 22, 2007. – OMG Board of Directors votes to adopt UML Profile for DoDAF and MODAF.
The OMG Board of Directors has voted to adopt the UML Profile for DoDAF and MODAF (UPDM). The UPDM specification defines a UML Profile for the Department of Defense Architecture Framework (DoDAF) and the Ministry of Defence Architecture Framework (MODAF)that can be used with the UML and SysML modeling languages.
