What is SysML?
The OMG systems Modeling Language (OMG SysML™) is a general-purpose graphical modeling language for specifying, analyzing, designing, and verifying complex systems that may include hardware, software, information, personnel, procedures, and facilities. In particular, the language provides graphical representations with a semantic foundation for modeling system requirements, behavior, structure, and parametrics, which is used to integrate with other engineering analysis models.

SysML and OpenEcology
SysML can provide engineering rigor to the overarching, "big picture" OpenEcology project, especially at the "seams" between the above-highlighted areas.
