| TrSSCom (Trustworthy Service Selction and Composition)
The TrSSCom project is aimed to develop a comprehensive framework for design,select and compose
trustworthy distributed systems from existing software services using principles of trust models,
subjective logic, multi-level specifications and matching, theory of evidence, and continuous testing.
Unlike prevalent approaches that focus on one view or a specific application domain, this research is
developing a generic model for trust that considers the internal and external views, an associated
formalism, and its application to distributed systems.
| UniFrame (Framework for Seamless Integration of Heterogeneous Distributed Components)
The UniFrame Approach (UA) provides a framework that allows an interoperation of heterogeneous and
distributed software components and incorporates the following key concepts: a) a meta-component model
(the Unified Meta Model - UMM), b) an integration of QoS at the individual component and distributed
system levels, c) the validation and assurance of QoS, based on the concept of event grammars, and e)
generative rules, along with their formal specifications, for assembling an ensemble of components out
of available choices.
