An OCL Semantics Specified with QVT

Slavisa Markovic

Metamodeling became in the last decade a widely accepted tool to describe the (abstract) syntax of modeling languages in a concise, but yet precise way. For the description of the language's semantics, the situation is less satisfactory and formal semantic ...

Looking Ahead in Open Multithreaded Transactions

Maxime Monod

Open multithreaded transactions constitute building blocks that allow a developer to design and structure the execution of complex distributed systems featuring cooperative and competitive concurrency in a reliable way. In this paper we describe an optimiz ...

Validation of Visual Contracts for Services

Alain Wegmann, Lam Son Lê, José Diego de la Cruz Garcia

Visual modeling languages have specialized diagrams to represent behavior and concepts. This diagram specialization has drawbacks like the dif-ficulty to represent the effects of actions. We claim that visual contracts can de-scribe actions in a more compl ...

A Method of Functional Alignment Verification in Hierarchical Enterprise Models

Alain Wegmann, Irina Rychkova

Enterprise modeling involves multiple domains of expertise: requirements engineering, business process modeling, IT development etc. Our experience has shown that hierarchical enterprise models, made of an assembly of system models, are effective. In these ...

OCL and Graph-Transformations – A Symbiotic Alliance to Alleviate the Frame Problem

Many popular methodologies are influenced by Design by Contract. They recommend to specify the intended behavior of operations in an early phase of the software development life cycle. Formal contract specification languages, however, are still rarely used ...

Action Semantics in Smart Objects

Daniel Thalmann, Tolga Abaci, Jan Ciger

We present a method of formal description of the action semantics in smart objects. Smart objects were primarily used for behavioral animation in the past. We demonstrate, how a formally described semantics can be used for action planning purposes by intel ...
