Nice description of Service Oriented Architecture (SOA): "Rather than have a calendar or scheduling function in every computer system that needs it, you have just the one calendaring component that exposes its service to anything or anyone who wants it." One major advantage of this approach is that "small and simple home-spun tools that make a real difference in teaching and learning can piggy-back on the functionality of bigger systems." The trick, of course, is to make this work. This is where standards and specifications really come to the fore, but you have to get them implemented, and even more importantly, documented.
