Verifying bigraphical models of architectural reconfigurations

ARCHERY is an architectural description language for modelling and reasoning about distributed, heterogeneous and dynamically reconfigurable systems. This paper proposes a structural semantics for ARCHERY, and a method for deriving labelled transition systems (LTS) in which states and transitions represent configurations and reconfiguration operations, respectively. Architectures are modelled by bigraphs and th...

Analysing tactics in architectural patterns

We present an approach to analyse the application of tactics in architectural patterns. We define and illustrate the approach by resorting to Archery, a language for specifying, analysing and verifying architectural patterns. The approach consists of characterising the design principles of an architectural pattern as constraints, expressed in the language, and then, establishing a refinement relation based on t...

A language for behavioural modelling of architectural patterns

The complexity of interactions governing the coordination of loosely-coupled services, which forms the core of current software, brought behavioural issues up to the front of architectural concerns. This paper takes such a challenge seriously by lifting typical behaviour modelling techniques to the specification of both types and instances of architectural patterns in which the later ones are connected by ports...

Bigraphical modelling of architectural patterns

Selected for publication in FACS'2011 post-proceedings, to appear in Springer Lecture Notes in Computer Science ; Archery is a language for behavioural modelling of architectural patterns, supporting hierarchical composition and a type discipline. This paper extends Archery to cope with the patterns' structural dimension through a set of (re-)configuration combinators and constraints that all instances of a pa...

Towards rigorous analysis of open source software

Workshop proceedings with local publication by the University of Oslo ; This paper discusses the (often hidden) potential of Open Source Software development to resort to, benefit from and cross-fertilize formal engineering methods, whose role is indisputable in the production of trustworthy software components. A strategy addressing the incorporation of formal verification methods in the Open Source Software ...
