I've been banging on the RESTful services/XRX bandwagon for a while now, and the good folks at O'Reilly have kindly consented to let me get out the entire trap drum set for an O'Reilly Webinar entitled "Building RESTful Services with XQuery and XRX".
For those of you unfamiliar with the the concepts, RESTful services are essentially a form of web services that take a very different approach to architecture from the traditional SOA-type services. They are built upon the idea of REST, and specifically around the idea that if you treat the web as a database of collections of documents (some real, some virtual) and use what amounts to a publishing or CRUD approach to accessing those documents, that you can in fact still create very rich applications that have the advantages of being easier to deploy, easier to manage, more scalable and in general simpler to use than both SOA and traditional web applications, while at the same time cutting down fairly dramatically on interdependencies and bottlenecks.
I'll be covering RESTful services in general and will demonstrate a simple RESTful service built around XQuery, REST and XForms as part of a 90 minute presentation on Wednesday, January 28 at 10am PST. Attendance is limited, so you'll need to register at http://oreilly.com/go/restfulservices. See you then!
