Background and motivation

The development of composite services poses very interesting
challenges concerning their Quality of Service (QoS) characteristics.
On the one hand, a composite Web Service depends on the QoS properties
of its own Web Service suppliers in order to provide a satisfactory
service to the user. On the other hand, the main issues for
the fulfillment of QoS and service level agreements are concerned
with Web service performance variability. Indeed, the QoS of a
Web Service may evolve relatively frequently, either because of
internal changes or because of workload fluctuations.
The performance of the composite Web service may be significantly
improved by monitoring the execution of the component Web Services
and by flexibly reacting to faults and anomalies in a timely fashion.

The concept of self-healing Web Service has been introduced
in order to describe services which exhibit such properties.
A self-healing Web Service can repair itself if any execution problems
occur, in order to successfully complete its own execution,
while respecting QoS agreements. In the design of a self-healing WS,
several aspects have to be considered. For instance,
the service should be able to detect failures as soon as possible and
to enact suitable recovery actions. Moreover, different QoS
service levels might be considered in order to complete
the service execution in case of error, possibly with degraded performance.

Call for papers ************

For this workshop, we will consider contributions devoted to Web Services,
QoS management, diagnosis and autonomic services.
Specifically, the relevant topics include, but are not limited to:

• Distributed and centralized solutions for the diagnosis and repair of choreographed and/or orchestrated Web Services
• Design for the diagnosability and repairability of Web Services
• QoS management in choreographed and/or orchestrated Web Services
• Monitoring simple and composite Web Services
• Ontologies for QoS
• Dynamic reconfiguration of Web Services
• Predictive QoS management for Web Services
• Autonomic services

Workshop format

The goal of this workshop is to bring together researchers and practitioners,
both from the Academia and from the Industry, working in the areas of
Web Service composition, QoS management and diagnosis,
who investigate concepts, methods, techniques, and tools to
design and manage self-healing Web Services.

All contributions will be made available in a Web site before the main conference,
so that participants can read them in advance.
Morever, a CD including the contributions and pre-proceedings will
be distributed at the conference.
After the workshop, post-proceedings will be prepared and published
in a volume edited by Springer (the post-proceedings will include the
papers presented at all the BPM 2008 workshops and reviewed on the basis of the discussion).

Moreover, the best paper of each workshop will be invited to a special
issue of the "Software Process Improvement and Practice" Journal: best
papers will undergo a further peer revision process in order to select
the subset to be published in the special issue.
