SysML is an extension to UML to try and accomodate systems. AADL is a textual language, intended right from the start for system design. A feature-by- feature comparison would be too long for this thread... > Is it really > necessary to create yet another System level design language? This is a good question that should be directed to the SysML people. AADL evolved from MetaH, which was in use in avionics systems long before the SysML effort started. AADL is a registered standard *today*, while SysML is still in the early phases. > Wouldn't > these folks be better off trying to influence SysML which is currently > being defined. There is also a UML profile that will achieve standardization soon. We would have loved to have the OMG people participate, rather than starting their own effort from scratch. > Since OMG standards are freely available they will > probably have more impact, right or wrong IMHO and be more widely > adopted. I industry makes technical decisions based on the selling price of a standard... then I'm afraid of the future of industry! Moreover, free availability of the standard is not the most important thing. AADL *today* has a free Eclipse plug-in (OSATE), emacs mode, free tutorials, etc. See http://www.aadl.info. -- --------------------------------------------------------- J-P.
