Abstract

This paper outlines the architecture of a system designed to demonstrate large scale web accessibility assessment developed in a European research project. The system consists of a set of integrated software components designed to automatically evaluate accessibility metrics for a large number of websites and present results in a common report. The system architecture is designed to be maintainable, scalable, and extensible in order to facilitate further development of the tool. To meet these design criteria within a limited set of resources, an Open Source approach is adopted both for selecting, designing and developing the software.
