Introduction

The TRAK.vss is a stencil for Microsoft Visio. It provides a set of node and connector elements in to allow you to create TRAK architecture views using the Microsoft Visio application.

It also provides:-

• attributes for each shape and connector to hold data e.g. protective marking, stereotype (element type)
• the ability to orient text on connectors - parallel, horizontal
• hovering over the shape or connector in the stencil provides the definition
• hovering over the shape in your drawing provides the description (from the underlying shape data)

It is an implementation of the logical definition of TRAK and as such may include limitations of the Visio tool.

Releases

This Release

Adds blocks and connectors to allow creation of TRAK MV-04 Assurance architecture view to allow description / structuring of Claims with supporting Arguments and Evidence e.g. for safety assurance claims, claims of compliance with a requirement, scientific claims etc.

Installation

Place in Documents | My Shapes and under whatever category you wish

Use

1. Make sure you are showing the Shape Data (right-click a shape and select 'Data | Shape Data' or go to the Data menu and select 'Shape Data Window' ).
2. Drag a shape from the stencil onto your drawing
3. In the Shape Data window enter the name of the shape. The name of the shape is taken from the contents of the 'Name' attribute.
4. In the Shape Data window enter the description for the shape.The description is taken from contents of the 'Description' attribute.
5. Complete as many of the attributes for the shape or connector as are needed.

TRAK Architecture Framework

Defining TRAK Documents

TRAK is defined by 3 documents.

The top level TRAK definition is at https://trak.sourceforge.io. This describes important ideas, choice of architecture description language, colour rules, bye laws, conformance with TRAK and the minimal modelling process. It invokes the following 2 documents:

• The specifications for TRAK architecture views (architecture viewpoints) are available at https://trakviewpoints.sourceforge.io

• The TRAK metamodel is available at https://trakmetamodel.sourceforge.io. This defines the architecture description elements, their properties, property values and triples.

Informative Documents

• TRAK-on-a-page.pdf provides a very short 4 page introductory guide to TRAK including the metamodel diagrams.
