By presenting state-of-the-art research results on various aspects of formal and visual modeling of software and systems, this book commemorates the 60^th birthday of Hartmut Ehrig.

The 24 invited reviewed papers are written by students and collaborators of Hartmut Ehrig who are established researchers in their fields. Reflecting the scientific interest and work of Hartmut Ehrig, the papers fall into three main parts on graph transformation, algebraic specification and logic, and formal and visual modeling.

This volume contains selected papers from WADT 2004, the 17th International Workshop on Algebraic Development Techniques. Like its predecessors, WADT 2004 focussed on the algebraic approach to the speci?cation and development of systems, an area that was born around the algebraic speci?cation of abstract data types and encompasses today the formal design of software systems, new speci?cation frameworks and a wide range of application areas. WADT 2004 took place at the Technical University of Catalonia (UPC), Barcelona, Spain, on 27 29 March 2004, and was organized by Fernando Orejas and Jordi...
