The ArchiMate® Enterprise Architecture Modeling Language

About the ArchiMate Modeling Language

The ArchiMate® Specification, a standard of The Open Group, is an open and independent modeling language for Enterprise Architecture that is supported by different tool vendors and consulting firms. The ArchiMate Specification provides instruments to enable Enterprise Architects to describe, analyze, and visualize the relationships among business domains in an unambiguous way. (Download a copy of the ArchiMate Specification)

Just as an architectural drawing in classical building architecture describes the various aspects of the construction and use of a building, the ArchiMate Specification defines a common language for describing the construction and operation of business processes, organizational structures, information flows, IT systems, and technical infrastructure. This insight helps stakeholders to design, assess, and communicate the consequences of decisions and changes within and between these business domains.


The ArchiMate Specification

Developed by The Open Group ArchiMate Forum,  the latest version of the ArchiMate Specification is version 3.1.
