This document starts the formalisation of the modelling language of the SOCCA OO method in the formal specification language Z. It captures the “static” aspects of SOCCA, i.e. the meaning of SOCCA language elements at the type level, rather than “dynamic” aspects (dealing with the instance level (objects in execution)). It is restricted to core SOCCA; proposed extensions are not formalised.

This note discusses a verification in PVS of the AID (Appli­ cation Identifier) class from JavaCard’s API. The properties th a t are verified are formulated in the interface specification language JML. This language is also used to express the properties tha t are assumed about the native methods from the Util class tha t are used in the AID class.

In this chapter, we present a framework for the evaluation and (re)design of modeling languages. In our approach, this property can be systematically evaluated by comparing a concrete representation of the worldview underlying the language (captured in the language ́s meta-model), with an explicit and formal representation of a conceptualization of that domain (a reference ontology). Moreover, w...

As the Unified Modeling Language is evolving into a family of languages with individually specified semantics, there is an increasing need for highly automated and provenly correct model transformations that would assure the integration of local views of the system (in the form of different diagrams) into a consistent global view. Graph transformation provides an easy-to-understand visual speci...

A b s tr a c t This paper reports on an effort to increase the reliability of JavaCard-based sm art cards by means of formal specification and verification of JavaCard source code. As a first step, lightweight formal interface specifications, writ­ ten in the specifica...

As software systems become larger and more complex, developers require the ability to model abstract concepts while ensuring consistency across the entire project. The internet has changed the nature of software by increasing the desire for software deployment across multiple distributed platforms. Finally, increased dependence on technology requires assurance that designed software will perfor...

Object oriented constraint programs (OOCPs) emerge as a leading evolution of constraint programming and artificial intelligence, first applied to a range of industrial applications called configuration problems. The rich variety of technical approaches to solving configuration problems (CLP(FD), CC(FD), DCSP, Terminological systems, constraint programs with set variables, . . . ) is a source of...

The TURTLE toolkit, or TTool for short, offers a real-time UML front-end and a user-friendly interface to simulation techniques and formal verification techniques such as reachability analysis, observer-based analysis and traceability matrices generation. TTool’s main strength is the total hiding of formal languages to UML modelers, while offering formal verification capabilities.

A practical tool for natural language modeling and development of human-machine interaction is developed in the context of formal grammars and languages. A new type of formal grammars, called grammars with prohibition, is introduced. Grammars with prohibition provide more powerful tools for natural language generation and better describe processes of language learning than the conventional form...

The Unified Modeling Language UML is well-suited for the design of real-time systems. In particular, the design of dynamic system behaviors is supported by interaction diagrams and statecharts. Real-time aspects of behaviors can be described by time constraints. The semantics of the UML, however, is non-formal. In order to enable formal design verification, we therefore propose to complement th...
