17:00-17:30 Closing & Discussion (Chair: Christian Zirpins)

The 2008 WESOA workshop has attracted a large variety of high-quality submissions. From these we have assembled an exiting program of technical sessions. WESOA 2008 is covering general principles of, specific methods for and concrete application perspectives on engineering service-oriented software applications. Moreover, we are delighted to announce that this year’s keynote address will be given by Keith Duddy, who will talk about challenging gaps between modern service-oriented systems and real world computing infrastructures.

What would Smart Services look like, and how can we build them on dumb infrastructure?

Abstract: The research for the next generation of service oriented systems development is well under way, and the shape of future robust and agile service delivery and service aggregation technologies is taking focus. However, the distributed computing infrastructure on which these systems must be built is suffering from years of “worse is better” thinking, and an almost invisible vendor fragmentation of the Business Process Modelling and Web Services spaces. The balkanisation of the basic technologies of process and service deployment threatens to undermine efforts to build the next generation of Smart Services. This talk paints a picture of services futures, reveals the problems of the present tangle of technologies, and points to some practical initiatives to find the way out of the mess.

Short Bio: Keith Duddy has been researching enterprise computing models and platforms for over ten years, building on his background of distributed systems standardisation and middleware services design. Keith worked for the DSTC Cooperative Research Centre, and was on the Architecture Board of the Object Management Group in 2000 when he contributed to the initial whitepaper on Model Driven Architecture. He was the editor of the first UML Profile that OMG standardised. Since then he has contributed to the maturation of MDA into MDE, Model Transformation, and the Domain Languages movement. Keith has chaired the Program Committee and the Organising Committee of the IEEE EDOC Conference. He is currently working for Queensland University of Technology, at the Smart Services Cooperative Research Centre, extending SOA by creating Service Delivery Frameworks that support Service Aggregation.
