Learners who use educational applications need to get suitable learning material in their concerned domain. However, their level of knowledge, preferences and interests are different. The e-learning system should be able to deliver suitable learning materials based on learner's preferences and knowledge. The solution is knowledge based personalized model-driven approach. The learner-model and domain-model plays an important role for delivering personalized learning material to learner. In this paper we proposed an ontological representation of learner-model with domain and educative support preferences along with this we described various categories of information that needs to be considered while developing the domain ontology for managing e-learning material. Finally the concerned architectural overview of ontology based e-learning system is proposed.
