About ArchiMate

ArchiMate®, an Open Group Standard, is an open and independent modelling language for enterprise architecture that is supported by different tool vendors and consulting firms. ArchiMate provides instruments to enable enterprise architects to describe, analyze and visualize the relationships among business domains in an unambiguous way.

Just as an architectural drawing in classical building architecture describes the various aspects of the construction and use of a building, ArchiMate offers 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 2.1 Specification

The ArchiMate 2.1 Specification is a maintenance update to ArchiMate 2.0, addressing comments raised since the introduction of ArchiMate 2.0 in 2012. The ArchiMate Specification is based on many years of practical experience of modeling and analysis of Enterprise Architecture (EA) by a world-wide user base. It enables the creation of fully integrated models of the organization’s enterprise architecture, the motivation for it, and the programs, projects and migration paths to implement it.

The detailed changes between version 2.0 and 2.1 are available as Document U132: ArchiMate 2.0 Specification Technical Corrigendum Number 1

The ArchiMate modeling language has evolved to be fully aligned with the TOGAF® standard:

  • By providing a vendor-independent set of concepts, that helps to create a consistent, integrated model “below the waterline”, which can be depicted in the form of TOGAF views
  • The ArchiMate® language enables modeling throughout the TOGAF® Architecture Development Method
  • The language structure of the ArchiMate Core corresponds with the three main architectures as addressed in phases B, C & D in the TOGAF® ADM
  • The extensions to the Core closely correspond with the main aspects to be addressed in the Preliminary phase, Phase A and the Central Requirements management repository, as well as Phases E, F, G and H

The Open Group ArchiMate® Model Exchange File Format (Phase 2) Snapshot Specification released for Comment

The Open Group has released a snapshot specification for Phase 2 of the ArchiMate Model Exchange File format - a standard file format for the exchange of ArchiMate models between different tools. The Snapshot is intended to make public the direction and thinking about the path The Open Group is taking. Feedback and guidance is requested. To provide feedback on this Snapshot, please send comments by email to no later than May 15, 2015.

The Snapshot can be obtained from The Open Group publications catalog at
(You will be required to register for an free web ID if you do not already have one).

This is the second Snapshot release of the exchange file format . It implements both phases of the
development of the file format, including new in this release the detailed visual layout.
The phases of development have been as follows:

  • Phase 1 includes the core exchange format.
  • Phase 2 includes in addition the visual layout.

The deliverables included with this Snapshot are as follows:

  • Open Group Snapshot, ArchiMate® Model Exchange File Format
  • Schema Documentation for the ArchiMate® 2.1 XML/XML Schema Definition (XSD) Binding
  • A ZIP file containing: the XSD Schema file, an example Extended XSD Schema file, and example models in the exchange file format

As proof of concept a plugin has also been released for the open source Archi tool.
