TOGAF 9.1 Vs Archimate 2.1

Both TOGAF 9.1 and the ArchiMate 2.1 Modeling Language have been developed and maintained by The Open Group.

TOGAF describes the process of developing and managing an enterprise architecture, but it doesn’t contain a defined modeling language structure. ArchiMate is meant to be complimentary to the TOGAF content framework and architecture development process.

So what are the differences?

ArchiMate is a multi-purpose modeling language, whereas TOGAF is an Architecture Development Framework.

Core
Core Relationship Types in ArchiMate

TOGAF provides a Single Holistic meta-model with relationships, while ArchiMate provides a High Level generic meta-model, as well as detailed per domain or layer meta-models.

Where TOGAF defines the logical and physical concepts, ArchiMate makes no distinction between logical and physical architecture components.

Archimate is diagram based, whereas TOGAF contains three different artifacts: Catalogues, Matrices and Diagrams.

TOGAF artifacts are agnostic and can be created using any modelling language. On the other hand Archimate viewpoints are specifically tailored to the Archimate languages.

Archimate relationships have a simplified structure and provide better support for cross domain relationships. On the other hand, TOGAF has many relationships which makes it difficult to maintain consistency, especially when using different notations.

TOGAF has a clearly defined Architecture Development Method but Archimate has no defined architecture development process or method.
