Patterns for Screenography

The visual design development of Web Information Systems is a complex task. At present, the process is mainly based on experiences and seems to be an immovable part of art, because there is no systematic concept to develop the layout from intentional towards presentational level. Typically, there is a late consideration of graphical issues that results in inflexibility and cause problems for extension and change management. Therefore, we propose an early involvement of layout and playout. Further, we follow a pattern-based approach to be able to reuse concepts. This paper introduces such patterns and try to clarify their structure and task for the whole development. Because the WIS development process is based on six dimensions, we initially introduce development dimensions.
