An environment for defining and handling guidelines for the Web

Several accessibility and usability guidelines are proposed more and more. In this paper we present an environment for defining, handling and checking guidelines for the Web. The goal of such a tool is to support developers and evaluators in flexibly handling multiple sets of guidelines, which can be dynamically considered in the evaluation process. In particular, an interactive editor has been designed to assist the evaluators in abstracting and specifying new and existing guidelines in our XML-based Guideline Abstraction Language (GAL), which are then stored in external files. Our tool is able to check any guidelines specified in this language without requiring changes in its implementation.
