"A complex system that works is invariably found to have evolved from a simple system that worked." --John Gall, Systemantics To design a website you need to know about HTTP, XHTML, and URIs. To design a web application you need to know about HTTP, XHTML, and URIs. To design a web service you need to know about XML, SOAP, WSDL, UDDI, WS-Policy, WS-Security, WS-Eventing, WS-Reliability, WS-Coordination, WS-Transaction, WS-Notification, WS-BaseNotification, WS-Topics, WS-Transfer... What happened there? The web is the most successful distributed platform in the world, and it's simple enough for average humans to understand. How come adapting it for use by computer programs requires that smart people spend billions of dollars and devote years of their lives to coming up with all these new standards? And what happened to HTTP and URIs? The answer is that "Web Services" aren't the web. They're a heavyweight architecture for distributed object access, like COM and CORBA. This architecture is associated with the web, because HTTP is a trendy protocol, and flexible enough that you can implement almost anything on top of it. But it's not really of the web. The architecture of Big Web Services reinvents or ignores every feature that makes the web successful. This is the book that puts the "web" back into "web services". You can design a web service that uses HTTP, XHTML, and URIs. You just need to understand REST, the architectural principles that drive the web. RESTful Web Services gives you the tools you need to argue for sensible web services, and the strategies and code you need to create them. The book is manuscript complete at around 440 pages, and it'll be published by O'Reilly in May 2007. We think this can be the definitive work on the real-world use of REST.

The importance of the UDDI standard in the future of SOA is highlighted in a new Burton Group Inc. report, "Registry Services: The Foundation for SOA Governance" by Anne Thomas Manes, research director at the analyst firm. In this interview, Manes explains why after being ignored for so long, the OASIS UDDI standard now at version 3.0, is finally moving up the adoption curve.

Emerging web services standards such as SOAP, WSDL and UDDI will enable system-to-system integration that is easier than ever before. This site lists publicly available web services.

web services discovery thing - no idea but supposed to be good
