Title	WS-Diamond – Web Services: DIAgnosability, MONitoring and Diagnosis
Responsable	Marie-Odile Cordier
Begin	2005
State	Ongoing
Description	WS-Diamond is a European project (Specific Targeted Research Project or STREP) dedicated to developing a framework for self-healing web services. It started in September 2005 and will last 36 months. It will produce - an operational framework for self-healing service execution of conversationally complex web services. Monitoring, detection and diagnosis of anomalous situations, due to functional or non-functional errors (as quality of service), is carried on. Repair/reconfiguration is performed, guaranteeing reliability and availability of web services; -a methodology and tools for service design that guarantee effective and efficient diagnosability/repairability during execution. The results will be demonstrated on real applications. Our team is mainly involved in the fourth and fith work packages (WP4 and WP5). WP4 is concerned with model-based diagnosis and repair of cooperative web services. The challenge of this work package is to apply recent results and techniques developed for monitoring and reconfiguring complex physical systems, as telecommunication networks, to web services networks. We are currently developing a distributed chronicle recognition approach adapted to this new application area. WP5 is dedicated to developing a design methodology to ensure the dependability of web services. Our work in this work package concerns the definition of self-healability properties in order to ensure that the system can be both diagnosed and repaired.
