Interoperability is guaranteed using semantic Web technologies, which allow describing the reports by RDF (Resource Description Framework) triples. The reports refer to elements of a knowledge base consisting of vocabularies, ontologies and rules of inference, in which the conceptual relations between accessibility standards, as WCAG (Web Content Accessibility Guidelines) or Section 508 among others, are formalized previously. A software prototype that uses the Apache Jena framework for implementing the process is presented. Keywords: Interoperability, Semantic Web, Software Testing, Web Accessibility. 1. Introduction The accessibility of a Web application is essential to make it understandable, usable and practical for all users, including disabled people. The evaluation of the accessibility of a website must be done checking the compliance of accessibility requirements established by well-known specifications, standards or laws. The most used standard is WCAG (Web Content Accessibility Guidelines) [20], created by the World Wide Web Consortium (W3C) and adopted as a standard by the International Organization for Standardization (ISO) [8]. Another important set of accessibility requirements are the ones included in the American Law known as Section 508 [21].
