“…These automata can be seen as concrete realisations of the more abstract framework [12,2]. By automatically distilling a concrete, minimised representation of a process as a history dependent automata, we can expect applications in model checking and verification along the lines of [1].…”

We apply the recently developed techniques of higher order abstract syntax and functorial operational semantics to give a compositional and fully abstract semantics for the π-calculus equipped with open bisimulation. The key novelty in our work is the realisation that the sophistication of open bisimulation requires us to move from the usual semantic domain of presheaves over subcategories of Set to presheaves over subcategories of Rel. This extra structure is crucial in controlling the renaming of extruded names and in providing a variety of different dynamic allocation operators to model the different binders of the π-calculus.

“…The finiteness property given by the HD-automata has been exploited to automatize the check of behavioral properties. Indeed, a semantic-based verification environment for the π-calculus, called HD Automata Laboratory (HAL) [1,2] has been implemented and experimented (http://fmt.isti.cnr.it:8080/hal). HAL is written in C++ and compiles with the GNU C++ compiler (the GUI is written in Tcl/Tk), and runs on SUN stations (under SUN Solaris 2.x) and on Linux machines.…”

“…In other words, the toolkit can be dynamically encompass a variety of verification techniques. Finally, the toolkit has been developed by targeting also the goal of extending an available verification environment (HAL [1,2]) with new facilities provided as WEB services. This has given us the opportunity to verify the effective power of the WEB service approach to deal with the reuse and integration of "old" modules.…”

Abstract. Web services allow the components of applications to be highly decentralized, dynamically reconfigurable. Moreover, Web services can interoperate easily inside an heterogeneous network environment. The vast majority of current available verification environments have been built by sticking to traditional architectural styles. Hence, they are centralized and none of them deal with interoperability and dynamic reconfigurability. In this paper we present a verification toolkit whose design and implementation exploit the Web service architectural paradigm. We describe the architectural design and the discuss in detail the current implementation efforts.

Abstract. In this paper an extension of a behavioural subset of UML Statecharts for modeling mobility issues is proposed. In this extension we relax the unique association between each Statechart -in a collection of Statecharts modeling a system -and its input-queue and we allow the use of (queue) name variables in communication actions. The resulting communication paradigm is much more flexible than the standard asymmetric one and is well suited for the modelling of mobility-oriented as well as fault tolerant systems.
