The static and dynamic relationships between the system actors and objects, but also the domain and business constraints must be taken into consideration in order to produce a consistent specification. Actual tools mainly support relationships and forget constraints. It is nevertheless necessary to have tools which enable to express and to validate them. In order to enable the validation of con...

This position paper presents work in progress on a formal model for the composition of object-oriented hyperslices with method-level join points. With the formal model, we should be able to study existing approaches such as subject-oriented programming, as well as extend other object-oriented languages, such as the UML, to accommodate the use of hyperslices. We show here a sample of the specifi...

This paper presents a case study in formal specification and verification of a smart card application. The application is an electronic purse implementation, developed by the smart card producer Gemplus as a test case for formal methods for smart cards. It has been annotated (by the authors) with specifications using the Java Modeling Language (JML), a language designed to specify the functiona...

The Unified Modeling Language (UML) is the de facto standard for designing models of software systems in both industry and academia. UML has many advantages, and is often the tool of choice when conveying information between various stakeholders. UML’s main disadvantage is that it is too abstract – resulting in ambiguous models. In safety critical systems, ambiguity could result in the loss of ...

Syntax Can Make the Definition of Modelica Less Abstract David Broman and Peter Fritzson Department of Computer and Information Science Linköping University, Sweden {davbr,petfr}@ida.liu.se Abstract. Modelica is an open standardized language used for modeling and simulation of complex physical systems. The language specifiModelica is an open standardized language used for modeling and simulatio...

In this paper we show how a modeling language from the area of business process engineering can be formally specified using meta modeling concepts. This serves as a basis for the implementation on an industry-scale meta modeling platform. For this purpose we revert to the Horus modeling method and the FDMM formalism that has recently been introduced to formally describe meta models and models. ...

Formal verification of time-dependent properties is crucial in the development of real-time reactive systems for safety-critical applications. Systems modeled in UML (Unified Modeling Language) result in graphic descriptions of the static structure and dynamic behavior of a system and its components. Generating a formal specification from the UML models supports rigorous techniques for validati...

This paper discusses links that may be made between process models and UML software specification techniques, working from an argument that the whole complexity of organisational activity cannot be captured by UML alone. The approach taken is to develop a set of use cases which would be capable of providing information support to a pre-defined organisational process. The nature of the thinking ...

The Unified Modeling Language (UML) has received wide acceptance as a standard language in the field of software specification by means of different diagram types. In a recent version of UML, the textual Object Constraint Language (OCL) was introduced to support specification of constraints for UML models. But OCL currently does not provide sufficient means to specify constraints over the dynam...

The textual Object Constraint Language (OCL) is an official part of the Unified Modeling Language (UML). OCL is primarily used to formulate restrictions over UML models, in particular, invariants and operation preand postconditions in the context of class diagrams. However, OCL is missing means to specify constraints over the dynamic behavior of a UML model. We have therefore developed a tempor...
