TRAK Information











TRAK is a general purpose and pragmatic enterprise architecture framework which has its roots in the UK MoD's MODAF 1.2.

TRAK allows you to describe an enterprise, a concept, a solution (and its procurement) and an architecture task. In ISO/IEC/IEEE 42010 terms each is a ‘system of interest’ and has stakeholders who have concerns that need to be addressed through the resulting architecture description.

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

TRAK adopts the ISO/IEC/IEEE 42010 approach where


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


The international standard for architecture description for systems and software engineering is ISO/IEC/IEEE 42010. The latest release was in 2011 (i.e. ISO/IEC/IEEE 42010:2011).

TRAK was designed from the outset to be compliant with the standard. The basis of the claim of conformance together with the supporting arguments and evidence is described using TRAK MV-04 Assurnace Views (based on claims, arguments and evidence metamodel elements) and presented as an architecture description (too good an opportunity to miss!) exported as a separate set of linked web pages. This contains the output provided for formal assessment of the claims.

The claims fall into 2 main areas:-

TRAK. Architecture Description. Conformance Assessment - ISO/IEC/IEEE 42010:2011.


TRAK Enterprise Architecture Framework Document

The TRAK Enterprise Architecture Framework document is a specification.

Where Does this Fit In?

The TRAK Enterprise Architecture Framework document is part of the logical definition of TRAK.

The TRAK Enterprise Architecture Framework document invokes the other parts of the definition:

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 known implementations of TRAK are listed separately.
