We propose the development of a framework for the dynamic interpretation of trust models, defined via a domain specific language. A trust model usually defines abstractions, the interpretation of which change in conjunction with changes in the domain or changes in the context in which the program executes. In a scenario where trust model assumptions encoded in the DSL change, programmers must still...
Digital systems have been rapidly evolving within highly dynamic and unstructured environments, where the lack of a central authority forces entities to interact with each other through collaboration and negotiation. Digital agents often use Trust models in order to compute the level of trustworthiness of the partner they want to collaborate with. Unfortunately, due to the evolution speed of open...
For the realization of language-independent, effective, and user-friendly model versioning systems, generic and efficient conflict detection is essential for correct and complete identification of conflicts caused by parallel modifications on one artifact. Usually, the genericity of the conflict detection costs a high price: language-specific operations and refactorings often remain undetected. Consequently,...
This work explores how model-driven engineering techniques can support the configuration of systems in domains presenting multiple variability factors. Video surveillance is a good candidate for which we have an extensive experience. Ultimately, we wish to automatically generate a software component assembly from an application specification, using model to model transformations. The challenge is...
The trust management in P2P networks allow to establish the trust relationships among the peers and decide whether the considered transaction will be realized. It tries to ensure safety in the extremely unsafe environments of P2P networks. In this paper we focus on the formal description of requirements of trusted P2P networks and we propose the model which is able to measure them. Our model should...
