The Semantic Web provides a common framework that allows data to be shared and reused acrossapplications, enterprises, and community boundaries. The existing web applications need to expresssemantics that can be extracted from users' navigation and content, in order to fulfill users' needs.E-learning has specific requirements that can be satisfied through the extraction of semantics from learningmanagement systems (LMS) that use relational databases (RDB) as backend. In this paper, we proposetransformation rules for building owl ontology fromthe RDB of the open source LMS Moodle. It allowstransforming all possible cases in RDBs into ontological constructs. The proposed rules are enriched byanalyzing stored data to detect disjointness and totalness constraints in hierarchies, and calculatingtheparticipation level of tables in n-ary relations. In addition, our technique is generic; hence it canbe appliedto any RDB
