OMG Systems Modeling Language V1.1

This specification defines a general-purpose modeling language for systems engineering applications, called the OMG Systems Modeling Language (OMG SysMLTM). Throughout the rest of the specification, the language will be referred to as SysML.
SysML supports the specification, analysis, design, and verification and validation of a broad range of complex systems. These systems may include hardware, software, information, processes, personnel, and facilities.
The origins of the SysML initiative can be traced to a strategic decision by the International Council on Systems Engineering’s (INCOSE) Model Driven Systems Design workgroup in January 2001 to customize the Unified Modeling Language (UML) for systems engineering applications. This resulted in a collaborative effort between INCOSE and the Object Management Group (OMG), which maintains the UML specification, to jointly charter the OMG Systems Engineering Domain Special Interest Group (SE DSIG) in July 2001. The SE DSIG, with support from INCOSE and the ISO AP 233 workgroup, developed the requirements for the modeling language, which were subsequently issued by the OMG as part of the UML for Systems Engineering Request for Proposal (UML for SE RFP; OMG document ad/2003-03- 41) in March 2003.
