The aim of the SASO conference series is to provide a forum for laying the foundations of a new principled approach to engineering systems, networks and services based on self-adaptation and self-organization. UAAR presented two papers at this conference.

The paper "Semantic Web based Self-management for a Pervasive Service Middleware" proposes and presents a semantic web based selfmanagement approach for a pervasive service middleware where dynamic context information is encoded in a set of self-management context ontologies. The proposed approach is justified from the characteristics of pervasive computing and the open world assumption and reasoning potentials of semantic web and its rule language.

The other paper entitled "Towards Self-Managed Executable Petri Nets" introduce a self-management approach which combines high-level Petri Nets with the capability of distributed communication among nets. Organized in a three-layer Goal Management, Change Management, and Component Control architecture this allows for self-management in distributed systems. The paper validates the approach through the Flamenco/CPN middleware that allows for self-management of service-oriented pervasive computing systems through the runtime interpretation of Coloured Petri Nets.
