Learning Object Metadata in the context of Semantic Web

Metadata used to express learning objects are usually encoded in XML. In XML we can describe only the static structure of the document, and we have a limited freedom to express data and metadata. In this article we propose to use Resource Description Framework (RDF) to describe metadata, corresponding to Learning Object Metadata (LOM) data model according to the standard. By using RDF we can define concepts, we can give meanings, and we can also make relations between concepts. We think this is a necessary step forward in the context of Semantic Web and pedagogical objects; so this could lead to the next generation of describing metadata or even to reach higher level like ontology. We propose an on-line tool called RDF4LOM, to edit metadata in RDF.
