4. Copyright © 2006 4 GIT SysML Involvement - Overall Purpose Collaborate within SE DSIG: composable object (COB) concepts  SysML (esp. SysML parametrics) Leverage COB-based simulation template work to demonstrate and verify SysML capabilities CAD-CAE interoperability Systems-of-systems (SoS) knowledge representations... For further background and GIT SysML work-to-date: - See SE DSIG minutes/archives - Atlanta - 9/05, 12/05 - http://syseng.omg.org/ - http://www.pslm.gatech.edu/topics/sysml/
