A Pattern-Based Approach to Manage Model References

Model references play an important role in model integration, especially when models belonging to different domains are to be integrated. They are also needed in various model transformation tasks. In some cases, they need to be instantiated systematically, following certain rules. This calls for an instantiation specification of model references. In this paper we propose a pattern-based approach for modeling, specifying, and finally applying model references. We represent model references as so-called collaboration patterns, modeled as UML collaborations. We further describe the instantiation rules of collaboration patterns. A tool has been implemented for establishing the model references according to the specification, allowing the designer to assist in the process of semi-automated model reference instantiation. We demonstrate the usefulness of the approach and tools by applying them in designing Web service orchestrations

Model-Driven Development of Aspect-Oriented Software Architectures

[EN] The Model-Driven Development (MDD) paradigm has become widely spread in the last few years due to being based on models instead of source code, and using automatic generation techniques to obtain the final software product. Until now, the most mature methodologies that have been proposed to develop software following MDD are mainly based on functional requirements by following the Object-Oriented Paradigm. Therefore, mature MDD methodologies are required for supporting the code generation from models that specify non-functional requirements. The Aspect-Oriented Software Development (AOSD) approach was created to provide explicit mechanisms for developing non-functional requirements through reusable elements called aspects. Aspect-Oriented Software Architectures (AOSA) emerged to deal with the design of both, functional requirements and non-functional requirements, which opened an important challenge in the software engineering field: the definition of a methodology for supporting the development of AOSAs following the MDD paradigm. This new methodology should allow the code generation from models which specify functional and non-functional requirements. This paper presents a mature approach, called PRISMA, which deals with this challenge. Therefore, this contribution takes a step forward in the area presenting in detail the PRISMA MDD process, which has been applied to generate the code of several real applications of the tele-operated robotics domain. PRISMA MDD approach provides complete support for the development of technology-independent AOSAs, which can be compiled from high-level, aspect-oriented architectural models into different technology platforms and languages following an MDD process. This contribution illustrates how to apply the PRISMA MDD approach through the modelling framework that has been developed to support it, and a case study of a tele-operated robot that has been completely developed using this approach. Finally, the results obtained from the application of PRISMA MDD process to develop applications of the tele-operation domain are analyzed in terms of code generation.The work reported here has been partially sponsored by the Spanish MEC projects (DSDM TIN2008-00889-E and MULTIPLE TIN2009-13838), and MICINN (INNOSEP TIN2009-13849)Pérez Benedí, J.; Ramos Salavert, I.; Carsí Cubel, JÁ.; Costa Soria, C.
