XML, Processes and Objects Symposium Tuesday
XPO Chair: Bob Marcus
Rogue Wave
The XML, Processes and Objects (XPO) Symposium will provide visibility for the object community into the latest developments in the convergence of XML and Workflow applications. This is the most critical area for future B2B E-Business software architectures. XML-based messages can provide the foundation for cross enterprise applications. However the techniques developed by object technologists in modeling, standardization, and distributed computing will be essential for future development. The purpose of XPO is to stimulate work in this area.

The XPO Committee members are listed in the OOPSLA 2000 Committees section of the Program.

Convention Center – 208 A, B, C, D

10:30 am - 12:00 noon
Next Generation Workflow Processes –
Products, Standards and Research
Chair: Fred Cummins, EDS

Over the past several years, message queuing and XML have emerged as key elements for the integration of enterprise applications. Recently these technologies have been extended to business-to-business electronic commerce. These transfers of information represent links in enterprise and inter-enterprise business processes. Workflow management supported by industry standards will extend these technologies to provide greater flexibility, control and automation of business processes. This session will explore these frontiers of workflow management.

Advanced Workflow System Description
Christoph Bussler, Netfish

XML Standards for Workflow

Research Topics in Advanced Workflow
Brian Drabble, University of Oregon

1:30 pm - 3:00 pm
Portability and Interoperability Across Internet Marketplaces
Chair: Matthew Fuchs, CommerceOne

One of the strongest growth areas among E-Business applications is the B2B Marketplace. XML interfaces have made it possible for multiple customers and suppliers to trade online. However one of the serious roadblocks to the future growth of E-Business is the incompatibility between the XML messages and workflow processes supported by marketplace vendors. This session will provide the latest information on attempts to overcome this problem by vendors to the automotive manufacturers and other vertical industries. There will also be a presentation on the status of XML-based business message standards across marketplaces.

Interoperability Across Marketplaces Based on CommerceOne Experiences

3:30 - 5:00 pm
Simple Object Access Protocol (SOAP) – Alternate Viewpoints
Chair: Jeff Sutherland, VIRTMED Corp.

The Simple Object Access Protocol (SOAP) is a new application-to-application communication transport based on XML over HTTP. Several leading analysts have predicted that SOAP will be one of the dominant Internet protocols in the next few years. SOAP passes through firewalls and can be used as an underlying transport for distributed object communication (e.g. CORBA, DCOM). Although it was originally championed by Microsoft, SOAP has recently been endorsed as a W3C Web standard by IBM and HP but it is still uncertain how it will interact with other middleware. This session will present alternate positions on SOAP balanced by an experience report from a major user.
