In my opening blog entry I observed how how pervasive the use of technology is becoming in HE teaching, learning and research. I've just come across a recent paper (20 July 2004) on the JISC web site that helps to clarify the kind of coherent technical infrastructure that's needed to support and realise the potential to improve activities in a broad domain, such as e-learning. Service-Oriented Frameworks: Modelling the infrastructure for the next generation of e-learning systems (a PDF) explains an approach to infrastructure development to achieve the integration of a wide range of systems that is needed to realise the desired improvements. In this context, a framework comprises a broad set of services required to support the business of a community. Services are pieces of application logic or behaviour in the various systems - so a library management system could expose the item reservation business logic as a service to be consumed in the institution portal or VLE. Some services may be common to multiple applications and frameworks, for example authentication, authorisation and service registry functions. And typically this would all be achieved using Web Services technology.
