In the object-oriented world, much effort is spent into the development of dedicated tools to ease programming and to prevent programming errors. Recently, the techniques of model-driven engineering (MDE) have been proven especially valuable to manage the complexity of modern software systems during the software development process. In the world of answer-set programming (ASP), the situation is different. Much effort is invested into the development of efficient solvers, but the pragmatics of programming itself has not received much attention and more tool support to ease the actual programming phase would be desirable. To address this issue, we introduce the tool VIDEAS which graphically supports the partial specification of answer-set programs, applying technologies provided by MDE.
