We discuss the development of an OCL specification for the JAVACARD API. The main purpose of this specification is to support and aid the verification of JAVA CARD programs in the KeY system. The main goal of the KeY system is to integrate object oriented design and formal methods. The already existing specification written in JML (JAVA Modelling Language) has been used as a starting point for ...

This article describes ECML (ETRI CPS Modeling Language), a modeling langue for hybrid system simulation. ECML extends DEV&DESS (Discrete Event and Differential Equation System Specification), with conveniences in modeling and simulation. Modeling environment EcoPOD (ETRI CPS Open Developer) and visual simulator EcoSIM (ETRI CPS Simulator) support visual modeling and simulation. We introduce mo...

Specifications that are used in detailed design and in the documentation of existing code are primarily written and read by programmers. However, most formal specification languages either make heavy use of symbolic mathematical operators, which discourages use by programmers, or limit assertions to expressions of the underlying programming language, which makes it difficult to write complete s...

The Web Service Modeling Language (WSML) is a language for the specification of different aspects of Semantic Web Services. It provides a formal language for the Web Service Modeling Ontology WSMO which is based on well-known logical formalisms, specifying one coherent language framework for the description of Semantic Web Services, starting from the intersection of Datalog and the Description ...

Making Domain-Specific Modeling Languages a part of a tool chain, a part of a proven development process, or the subject of verification cannot be achieved without the precise specification of the language and the models expressed in it. Defining formal semantics for modeling languages is a widely accepted solution to this problem. We have developed methods, techniques and processes to provide ...

based on how formal a conversation is, how much familiar the speaker and the listeners are with each other and how distant is the speaker's social status from the listener's one, the speaker uses certain forms of language known as styles of language. linguistic styles are different from language varieties. selection of the styles depends on definite social situations and the kind of r...

Designing a correct model for distributed and reactive systems is the first goal of using Rebeca modeling language as an actor-based language supported by a formal verification tool. This paper proposes a method to perform formal verification of reactive systems at the early stages of the design cycle. We propose a UML profile for modeling systems consisting of reactive objects which are commun...

We present a formal semantics for the Object Constraint Language (OCL) which is part of the Uniied Modeling Language (UML) { an emerging standard language and notation for object-oriented analysis and design. In context of information systems modeling, UML class diagrams can be utilized for describing the overall structure, whereas additional integrity constraints and queries are speciied with ...

developing reliable yet flexible software is a hard problem. although modeling methods enjoy a lot of advantages, the exclusive use of just one of them, in many cases, may not guarantee the development of reliable and flexible software. formal modeling methods ensure reliability because they use a rigorous approach to software development. however, lack of knowledge and high cost practically fo...
