Tutorials take place from 9:00 to 12:15 am on Wednesday, June 3rd , just before the regular conference program. The first, Electronic Markets, is located at the conference venue, the other two take place in the house of 'Patriotische Gesellschaft', Trostbrücke 6, only a couple of steps from the conference venue.

Electronic Markets: A State of the Art Analysis
Prof. Dr. Beat Schmid, Dr. Hans-Dieter Zimmermann
The tutorial is divided into three major parts: In the first part we introduce concepts of Electronic Markets, its historic developments, basic mechanisms, and potentials. The second part gives a state of the art overview about recent developments in the field of Electronic Markets and Electronic Commerce. The phase model of a market transaction is used as the underlying framework, discussing EC developments in the information-, negotiation-/contracting- and settlement- (logistics and payment) phase of transactions. The tutorial concludes with an outlook towards the new perspective on Business Media and the embedding of Electronic Markets in this more general concept.

Prof. Dr. Beat Schmid is Director of the Institute for Media and Communications Management at the University of St. Gallen (MCM-HSG) since January 1998. Until end of 1997 he was Director of the Institute for Information Management at the same University. His research interests include the areas of Knowledge Media and Business Media.

Dr. Hans-Dieter Zimmermann is project manager of the Competence Center Electronic Markets (CC EM) at the Institute for Media and Communications Management at the University of St. Gallen (MCM-HSG). His major research interest concerns the field of Business Media, especially Electronic Markets (EM).

Business Objects - Current Status and Future Trends
Dr. Zoran Milosevic, Brian Wood
The maturing infrastructures for distributed systems such as CORBA, DCOM and Java-RMI are increasingly finding their way into enterprises. However, while they solve a number of technological problems in the interworking of applications written in different languages and using different platforms, they are still not addressing pressing requirements for business applications. In particular, there is a need for i) a means for expressing agreement on common semantics for concepts across business applications; ii) software facilities which enable implementation of these concepts, exploiting the benefits of underlying infrastructures. This tutorial gives an introduction to the emerging business object technology which aims to address these needs.

Dr. Zoran Milosevic is a Senior Research Scientist at the Cooperative Research Center for Distributed Systems Technology (DSTC Pty Ltd), Brisbane, Australia. He researches and consults on open distributed systems architectures, enterprise distributed object computing, business process modeling and electronic commerce. In 1997 he initiated and organized EDOC'97, the first international Enterprise Distributed Object Computing workshop.

Bryan Wood is project manager and technical architect of Open IT. He has wide experience in IT, covering language and compiler design, operating systems, real-time and communications-based systems, performance analysis and security. He is currently working on the object oriented specification and design of distributed applications and services. He is active in work on Open Distributed Processing (ODP) and the work of the Business Objects Domain Task Force in the OMG.

Secure Electronic Commerce
Dr. Günter Karjoth
As business is moving from face-to-face trading to electronic commerce over the Internet, crucial security issues are being raised. Essential concepts are multi-party security and dispute handling, and in many scenarios users have very strong privacy requirements. This tutorial discusses security risks and reviews the state of the art, in particular in electronic payment systems. The architecture proposed by the SEMPER consortium is used as a framework.

Dr. Günter Karjoth is a research staff member at the IBM Zurich Research Laboratory where he is currently working on access control issues in distributed and mobile object systems. His primary research interest is in network security, security models and policies, and electronic commerce. He is author of over 30 papers in technical journals and conference proceedings. He received his Diploma in Computer Science and his Ph.D. from the University of Stuttgart, Germany.
