IT-enabled operations are changing the face of global business. With the emergence of open standards such as HTTP, SOAP, and web services, .web-enabled. enterprise applications are expected to revolutionize the nature of large-scale distributed computing in a eScience, eResearch, and eBusiness. The next generation of enterprise applications is being built on service-oriented architecture principles, emphasizing loose coupling and high reuse, with XML and web services as the underlying implementation technology. The proposed workshop will provide a venue for academic and industry researchers to present and discuss issues and solution approaches for the design of scalable, configurable, and high-performance large-scale enterprise applications. As indicated by the title of the workshop, two aspects are of interest . engineering and optimization. Engineering encompasses issues in software engineering, software architecture and frameworks, development methodologies, design principles for web services and SOA, etc., that help create scalable, rapidly deployable, and configurable applications with reusable components and abstractions. Optimization refers to quantification and measurement of aspects such as ease of integration and reuse, in addition to traditional metrics such as latency, throughput, response time, etc.

Authors are invited to submit original unpublished manuscripts that demonstrate current research on performance measurement and optimization of such applications. Topics of interest include but are not limited to:

• Processes, frameworks, and methodologies
• Performance metrics and measurement strategies
• Innovative applications and performance evaluation of semantic web technologies
• Software architectures for reusability and rapid reconfiguration
• Large scale event modeling and management
• Service discovery, composition, availability, and adaptive reconfiguration
• Theoretical performance analysis: complexity, correctness, scalability, fault-tolerance
• Case studies related to engineering and optimization in real world deployments

Submitted manuscripts may not exceed 8 single-spaced pages using 11-point size font on 8.5x11 inch pages, including figures and tables. References may be included in addition to the 8 pages. Submissions will be judged on correctness, originality, technical strength, significance, quality of presentation, and interest and relevance to the workshop attendees. Submitted papers may not have appeared in or be under consideration for another workshop, conference, or a journal. Submission procedures will be made available at the workshop web site.

All manuscripts will be reviewed. Manuscripts must be received by September 15, 2007, by 5 p.m. U.S. Pacific Coast Time. Notification of review decisions will be mailed by October 22, 2007. Camera-ready papers will be due November 15, 2007.

Proceedings will be distributed at the workshop.
