TL;DR: An interactive editor has been designed to assist designers and evaluators in abstracting and specifying new and existing guidelines in an XML-based Guideline Abstraction Language (GAL) without requiring further changes in the tool implementation.
Abstract: More and more accessibility and usability guidelines are being proposed, especially for Web applications. Developers and designers are experiencing an increasing need for tools able to provide them with flexible support in selecting, editing, handling and checking guidelines. In this paper, we present an environment for addressing such issues. In particular, an interactive editor has been designed to assist designers and evaluators in abstracting and specifying new and existing guidelines in an XML-based Guideline Abstraction Language (GAL). Our tool has been designed in such a way to be able to check any guidelines specified in this language without requiring further changes in the tool implementation.
