Learning Objects (LOs) retrieval and sharing are important tasks on a Web based educational system, because it allows LOs provided by different sources to be found and reused by heterogeneous systems. This enables, among others, costs reduction during the LO production proccess, as educational content development is a time consuming task. Therefore, a formal and standardized representation, like IEEE Learning Objects Metadata (LOM), is needed to describe the LOs to make the aforementioned scenario possible. However, semantic operations like LOs relationship demand an ontological representation as metadata semantics is not well defined. To this end, this paper presents an ontology that uses the IEEE LOM standard to semantically represent LOs.
