Information technology — Object Management Group Unified Modeling Language (OMG UML) — Part 2: Superstructure

ISO/IEC 19505-2:2012 defines the Unified Modeling Language (UML), revision 2. The objective of UML is to provide system architects, software engineers, and software developers with tools for analysis, design, and implementation of software-based systems as well as for modeling business and similar processes.
