TRAK Viewpoints

TRAK is an enterprise architecture framework based on the UK MoD's MODAF 1.2.

TRAK provides a way of describing systems and their place in the world through architectural models. The elements used to make the TRAK models is defined by the TRAK Metamodel. The TRAK views that contain these elements are defined by TRAK Viewpoints.

TRAK adopts the ISO/IEC/IEEE 42010:2011 approach where each viewpoint specifies an individual TRAK architecture view in terms of:

An overview of the viewpoints and some examples of TRAK architecture views are provided.


Release of the TRAK Viewpoints are under the control of the TRAK Steering Group.

It contains:

Where Does this Fit In?

The TRAK Viewpoints document is one of 3 documents that defines the logical definition (free of implementation or solution) of TRAK together with:

The definition of TRAK is released through Sourceforge as open source.

Implementations of TRAK

TRAK can be implemented in a wide range of modelling tools and architecture description languages (a term taken from ISO 42010) such as UML, BPMN etc can be used to represent parts of the TRAK metamodel and therefore can be used in creating TRAK architecture views.

The implemementations of TRAK for various tools are listed separately on the overall TRAK project site on Sourceforge.
