Presentation by Arne Koesling at Lernen, Wissen, Adaptivität (LWA 2008), University of Würzburg, 6.-8. October 2008. Track: ABIS
Focus: Introduce Adaptability into regular Learning Management Systems (LMS) – introduce sophisticated rule systems (policies) that allow all stakeholders (learners , teachers, system admins) to adapt the system for their needs.
Policies are statements that define the behaviour of the system and are intended to guide decisions and actions. There are also known as business rules. For example: “New customers have to pay in advance, regular customers are allowed to pay after delivery” or “point all users to the basic material, if they enter the course the first time and notify all tutors”. Policies are dynamic, declarative, reusable, have a well-defined semantics, and allow for reasoning.
The author chose Protune as policy language, which additionally supports negotiations, explanations and integration with external sources (see concrete examples in Protune on the w3.org website).
