Semantic Web and Rule Reasoning inside of E-Learning Systems

This paper describes how the Semantic Web and the JenaRules can work together in order to empower e-Learning platform Moodle with rich reports and flexible courses management. We discuss aspects of using Semantic Web technologies in e-learning in general and the JenaRules in particular. The main focus is towards using rules for reasoning on top of existing Moodle content. Learning is an important aspect of our live. Online learning enables previously disqualified groups such as single parents and full time workers to learn outside the time constraints of conventional campus structures. Free software has delivered tools such as Moodle, Sakai, Atutor that fulfill this any time func-tionality with feature-rich sets and dynamically active group awareness. These online systems are also known as e-Learning Systems. Such systems provide an easy way for tutors to expose their courses, to interact with students, and to track student interest and activities over the presented domain. In addition, they have forums, where students and tutors can exchange opinions or receive answers to some questions. The use of Semantic Web technologies in e-Learning ([1]) may bring benefits to tutors and students. For example, a course tutor may want to know which students are active in a course or how many students use a recommended documentation for the course. A traditional solution to such problem is relational databases, but moving to RDF[2] is a shift to the open world with many distributed resources, identified by URIs as a mechanism for referring to global constants on which there exists some agreement among multiple data providers. Queries can be performed not only over a single database,
