Latest research work within ICT has outlined that future systems must possess the ability of adapting to changes in user requirements and application domains. Adaptation and evolution depend on several dimensions, e.g., time, location, and security conditions, expressing the diversity of the context in which systems operate. The Coordination Action (CA): Trustworthy Eternal Systems via Evolving Software, Data and Knowledge (EternalS) aims at coordinating research in the above-mentioned areas by means of a researcher Task Force and community building activities, where the organization of workshops and conferences is one of the important tools used for such purpose. EternalS aims at creating the conditions for mutual awareness and cross-fertilization among the four ICT-Forever Yours - FET projects (FP7-ICT-Call 3): LivingKnowledge, HATS, Connect and SecureChange. These projects are currently conducting research in key ICT areas: (i) automatic learning of systems capable of analyzing knowledge and diversity with respect to their complex semantic interactions and evolution over time, (ii) exploitation of formal methods for the design and networking of adaptive and evolving software systems; and (iii) design of security policies and fully connected environment. The above-mentioned projects will help EternalS to actively involve many researchers from both academic and industrial world in its action.
