Abstract
This research presents a method to describe Learning Objects as Semantic Web compatible Ontologies. The proposed method divides the Ontologies among three layers. The first is composed by the knowledge domain, the second by the LOs and their relations, and the third is responsible for knowledge inference and reasoning. As study case, it is presented the Ontologies of LOM and OBAA metadata standards as part of the Layer One. The layer two is composed by the description of sample Learning Objects based on the properties and restrictions defines by the layer one ontologies. The layer three describes the knowledge inference axioms, which we defined as Application Profiles. Our current results can be resumed as a contribution to Ontology Engineering for Semantic Web applied to Digital Education.

- 1.
The Learning Object Metadata Standard [8] has an element set used to describe Learning Objects, it is considered a reference for such activity.
- 2.
[17] was build mainly to extend LOM with platform interoperability aspects. It is a Brazilian Standard.
- 3.
The Friend Of A Friend vocabulary is used to describe the relationships among Agents for the Semantic Web.
- 4.
The LOM ontology is available to reuse through the following URIFootnote 5.
