Goal

In the overall topic of reliable software, we are specifically interested in improving the way software developers can manage the complexity of developing software which is most of the time distributed, based on existing reused pieces, and with stronger and stronger timing constraints. The goal of this workshop is to look at issues related to the integration of non-functional properties expression, evaluation, and prediction in the context of component-based software engineering development. It is now widely recognized that what makes Component-Based Software Engineering (CBSE) hard to efficiently use is the fact that components are easy to produce but not easy to compose. This scope is addressed by a number of ongoing researches. In the context of this particular workshop we would like to focus on the difficulty of predicting the overall behavior and offered quality of service (in a broad sense, e.g. performance, dependability) of a composite out of its "internal" components. This implies that a software builder should have the behavior and the quality of service offered and required of each components expressed in some way, as well as some support tool or underlying framework supporting the composition of these added-value features. The aim of this workshop is to bring together practitioners and academics that are currently working around these topics to highlight the ongoing solutions and the problems encountered. The workshop is organized on two half-day sessions. The morning session is dedicated to invited talks and presentations. Followed, in the afternoon, by working sessions. The number and subject of these sessions will be decided by the organizers depending upon the position papers.

Topics

A number of open questions will be addressed during the workshop. These questions will be refined, selected and modified according to the early discussions of the day, and some working sessions will be organized in order to give some indications on their answer. Examples of open questions:

How can I constraint/improve my component-based design with QoS annotations?
What research path should we take to make progress in predicting system behavior based on component behavior?
How do you decompose system behavior to get specific component requirements for non-functional system properties?

Previous workshops

Some of the organizers of this proposed workshop have already organized various workshops on related issues at conferences like UML, ECOOP, OOPSLA, or OOIS. The aim of the organizing team is to merge the initiatives in the modeling area with those in the performance evaluation area. For example a workshop close to the proposed topics has been held in the UML'2002 conference in Dresden and another one was a special issue of the International Symposium On Computer and Information Sciences, but the attendees were from different areas although the problems were related.

Submissions (Closed)

Researchers and practitioners were invited to submit position papers on topics related to the workshop. A partial list of topics was:

Composition Language
Software performance modeling and evaluation
QoS specification
ADLs and their use in supporting features composition
Software dependability
Compositionality
Modeling methods and tools for non-functional requirements
Industrial case studies

The 5-10 pages (single-spaced, 12-point, 1-inch margins) papers should be submitted either in postscript or as pdf file, via email to bruel@univ-pau.fr. The workshop organizers will review the submissions and select papers that present relevant and interesting ideas and concepts that can contribute to the discussions that will take place in the workshop. The workshop proceedings will be made available before the start of the workshop on the workshop website and may appear as a technical report at one of the organizers' universities.
