Current Web service composition approaches and languages such as WS-BPEL do not allow to define temporal constraints in a declarative and separate way. Also it is not possible to verify if there are contradictions between the temporal constraints implemented in the composition. These limitations lead to maintainability and correctness problems. In this(More)
In this paper, we propose an “end-to-end” approach that supports dynamic reconfiguration of software architectures taking advantage of graphical modeling, formal methods and aspect-oriented programming. There are three ingredients of the proposal. The specification end of the solution is covered by a new UML profile enabling to specify the desired(More)

In this context, organizations tend to rely more on business process management (BPM) to streamline their operations. The business process field is influenced by a wide range of temporal constraints which rise from legal, regulatory, and managerial rules. One of the(More)
Managing embedded system complexity and scalability is one of the most important problems in software development. To better address this problem, it is very recommended to have an abstraction level high enough to model such systems. Architectural description languages (ADLs) intend to model complex systems and manage their structure at a high abstraction(More)
OATAO is an open access repository that collects the work of Toulouse researchers and makes it freely available over the web where possible. Abstract—Security engineering with patterns is currently a very active area of research. Security patterns í an adaptation of Design Patterns to security – capture experts' experience in order to solve recurrent(More)
One key perspective when dealing with Business Process Management (BPM) is time. All business experts agree upon the fact that time is a key resource for each business process within an organisation. Indeed, time managing is an effective cost and error reduction strategy and thus ensures profit maximization for the organisation. As a result, business(More)
