Developing a RESTful API for a Web Accessibility Evaluation Tool

Nowadays, the evaluation of the accessibility of Enterprise Web Information Systems is based on the Web Content Accessibility Guidelines (WCAG 2.0), created by the World Wide Web Consortium (W3C) in 2008 and adopted in 2012 by the International Organization of Standardization (ISO) as ISO/IEC 40500 standard. Web accessibility evaluation tools are software programs or online services that help developers determine if web content meets the accessibility guidelines. This paper shows the extension of an existing online tool, with the aim of exposing its functionality also as an Application Program Interface (API). The original tool is used through a Web user interface, and this extension exposes functionality through web services based on REST technology, so that developers can invoke them from their own applications for accessibility testing.
