Introduction

TRAK is an enterprise architecture framework based on the UK MoD's MODAF 1.2. but substantially different in terms of its metamodel and the way in which view content is specified and applying consistency rules across the collection of views. TRAK metamodel elements have many properties that can be used to capture/better describe real world entities.

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.

It is important to note that TRAK views are defined as wholly triples - node - relationship - node e.g. 'Claim about System' or na set of triples e.g. 'Organisation plays Role extends to Software'. These form sentences or assertions which can be tested for consistency, path closure. They are readable by a non technical audience. It is the TRAK metamodel that provides these triples for the various TRAK Viewpoint definitions.

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

the questions or concerns it is designed to answer
a description of the view
what you must show
what you can show if you want
rules to help ensure that your model remains consistent

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

Governance of TRAK

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

TRAK Viewpoints Specification

The TRAK00001. TRAK. Enterprise Architecture Framework. Viewpoints specification defines architecture viewpoints - specifications against each of which a view is prepared and interpreted.

It contains:

a description of the TRAK perspectives used to group views of a similar nature
a definition of the colours used in TRAK
TRAK Bye Laws - overall rules
minimal modelling process for TRAK.
- how to select the views needed for the task
a definition of every single TRAK viewpoint (specification for an architecture view)
minimum allowed TRAK view sets

Where Does this Fit In?

The TRAK00001 TRAK. Enterprise Architecture Framework. Viewpoints specification is one of 3 documents that defines the logical definition (free of implementation or solution) of TRAK together with:

TRAK00004. TRAK. Enterprise Architecture Framework - an overall set of requirements (e.g. colour, conformance with TRAK, Bye Laws etc)
TRAK00002. TRAK. Enterprise Architecture Framework. Metamodel - the allowed elements and relationships and the triples that form the basis of the TRAK architecture viewpoints

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 languagesISO/IEC/IEEE 42010:2011 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.
