The Unified Modeling Language (UML) has been widely accepted as the standard object-oriented (OO) modeling language for modeling various aspects of software and information systems. The UML is an extensible language, in the sense that it provides mechanisms to introduce new elements for specific domains if necessary, such as web applications, database applications, business modeling, software development processes, data warehouses. Furthermore, the latest version of UML 2.0 got even bigger and more complicated with more diagrams for some good reasons. Although UML provides different diagrams for modeling different aspects of a software system, not all of them need to be applied in most cases. Therefore, heuristics, design guidelines, lessons learned from experiences are extremely important for the effective use of UML 2.0 and to avoid unnecessary complication. Also, approaches are needed to better manage UML 2.0 and its extensions so they do not become too complex too manage in the end. Already, the many UML extensions are not well integrated and the UML 2.0 metamodel has become very complex.

The Fifth International Workshop on Foundations and Practices of UML (FP-UML'09) intends to be a sequel to the successful BP-UML'05, BP-UML'06, FP-UML'07, and FP-UML'08 workshops held in conjunction with the ER'05, ER'06, ER'07, and ER'08, respectively. FP-UML'09 intends to be an international forum for exchanging ideas on the best and new practices of the UML in modeling and system developments. Papers focused on the application on the UML in new domains and new experiences with UML 2.0, and foundations, theory, and UML 2.0 extensions are also highly encouraged. As UML 2.0 is oriented towards the software design driven by models, papers applying the Model Driven Architecture (MDA) or the Model Driven Engineering (MDE) to specific domains are also highly encouraged. The workshop will be a forum for researchers, analyzers, designers, and users who use the UML to develop systems and software.
