Software Technologies: Applications and Foundations (STAF) is a federation of leading conferences on software technologies. It was formed after the end of the successful TOOLS federated event in 2012, providing a loose umbrella organisation with a steering committee that aims to provide continuity.
The STAF federated event runs annually. The conferences that participate may vary from year to year, but all focus on practical and foundational advances in software technology. The conferences address all aspects of software technology, from object-oriented design, testing, mathematical approaches to modelling and verification, transformation, model-driven engineering, aspect-oriented techniques, and tools.
