Defense architecture frameworks like DoDAF, MoDAF or NAF (UPDM) are widely accepted standards, not only in defense-related organizations. Because of different frameworks and vendor-specific implementations of the modeling language, interoperability isn´t always achieved easily and information exchange is hardly possible
IBM Rational® System Architect® (SA) is a great tool for enterprise architecture (EA) projects, e.g. using meta-models such as ArchiMate® from The Open Group. ArchiMate® has been implemented as a modeling language for SA by CORSO with support by IBM.
