This Festschrift volume has been published in honor ofFrank de Boer, on the occasion of his 60th birthday.Frank S. de Boer is a prominent member of the research community in formalmethods and theoretical computer science. A brief look at his lengthypublication list reveals a broad area of interest and a versatile modusoperandi with: logic and constraint programming; deductive proof systems,soundness, and completeness; semantics, compositionality, and full abstraction;process algebra and decidability; multithreading and actor-based concurrency;agent programming, ontologies, and modal logic; real-time systems, timedautomata, and schedulability; enterprise architectures, choreography, andcoordination; testing and runtime monitoring; and cloud computing and service-levelagreements. For a while, he also liked failures, especially in semantics, andoptimistically concluded with the failure of failures. In fact, Frank has anopportunistic approach to research. Rather than seeing obstacles, he findsopportunities.

This Festschrift volume has been published to celebrate the lifelong scientific achievements of Farhad Arbab on the occasion of his retirement from the Centre of Mathematics and Computer Science (CWI).

Over the years Farhad Arbab  has sucessfully been engaged in scientific explorations in various directions: Software Composition, Service Oriented Computing, Component-based Software, Concurrency Theory, Coordination Models and Languages, Parallel and Distributed Computing, Visual Programming Environments, Constraints, Logic and Object-Oriented Programming.

Farhad Arbab has shaped the field of Coordination Models and Languages. His insight that it is all about exeogeneous coordination gave rise to the striking elegance and beauty of Reo: an exogenous coordination model based on a formal calculus of channel composition. Reo has been extremely successful and is having a great impact in many of the areas mentioned above.

The present volume collects a number of papers by several of Farhad’s close collaborators over the years.
