Many changes lurk around the corner for enterprise architectures, including a wide adoption of Web services, message-based architectures, and eventually service-oriented architectures. Additionally, XML is quickly becoming the dominant wire protocol for transferring data between systems, and even between enterprises.
In an effort to begin transitioning to some of these new technologies, many enterprises are introducing services to their existing architectures. XML content routing is one of the most valuable of these early-adoption services for many enterprises wishing to glue their legacy systems to more modern Web-based systems.
This session focuses on the business case for this type of system, where such a system can be used, where it shouldn't be used, and what the patterns and available open source technologies are that facilitate building such a system. An example case study is presented for an XMLCR and the basic design of the system is presented.
