A Choreography-Driven Approach to APIs: The OpenDXL Case Study
We propose a model-driven approach based on formal data-driven choreographies to model message-passing applications. We apply our approach to the threat intelligence exchange (TIE) services provided by McAfee thr...

Reversing P/T Nets
Petri Nets are a well-known model of concurrency and provide an ideal setting for the study of fundamental aspects in concurrent systems. Despite their simplicity, they still lack a satisfactory causally rever...

Data-Driven Choreographies à la Klaim
We propose Klaim as a suitable base for a novel choreographic framework

A Denotational View of Replicated Data Types
“Weak consistency” refers to a family of properties concerning the state of a distributed system. One of the key issues in their description is the way in which systems are specified. In this regard, a major a...

A Formal Analysis of the Global Sequence Protocol
The Global Sequence Protocol (GSP) is an operational model for replicated data stores, in which updates propagate asynchronously. We introduce the GSP-calculus as a formal model for GSP. We give a formal accou...

A Normal Form for Stateful Connectors
In this paper we consider a calculus of connectors that allows for the most general combination of synchronisation, non-determinism and buffering. According to previous results, this calculus is tightly relate...

From Hierarchical BIP to Petri Calculus
We focus on Hierarchical BIP, an extension of Joseph Sifakis et al’s BIP component framework, to provide a semantics-preserving, compositional encoding in the Petri calculus, a recently proposed algebra of sta...

Resolving Non-determinism in Choreographies
Resolving non-deterministic choices of choreographies is a crucial task. We introduce a novel notion of realisability for choreographies –called whole-spectrum implementation– that rules out deterministic impleme...

On the Behaviour of General-Purpose Applications on Cloud Storages
Managing data over cloud infrastructures raises novel challenges with respect to existing and well studied approaches such as ACID and long running transactions. One of the main requirements is to provide avai...

Chapter
Behaviour, Interaction and Dynamics
The growth and diffusion of reconfigurable and adaptive systems motivate the foundational study of models of software connectors that can evolve dynamically, as opposed to the better understood notion of stati...

A Survey on Basic Connectors and Buffers
Recent years have witnessed an increasing interest about a rigorous modelling of (different classes of) connectors. Here, the term connector is used to name entities that can regulate the interaction of possib...

Connector Algebras, Petri Nets, and BIP
In the area of component-based software architectures, the term connector has been coined to denote an entity (e.g. the communication network, middleware or infrastructure) that regulates the interaction of indep...

A Connector Algebra for P/T Nets Interactions
A quite flourishing research thread in the recent literature on component-based system is concerned with the algebraic properties of various kinds of connectors for defining well-engineered systems. In a recen...

Transactional Service Level Agreement
Several models based on process calculi have addressed the definition of linguistic primitives for handling long running transactions and Service Level Agreement (SLA) in service oriented applications. Neverth...

A Fuzzy Approach for Negotiating Quality of Services
A central point when integrating services concerns to the description, agreement and enforcement of the quality aspect of service interaction, usually known as Service Level Agreement (SLA). This paper present...
