This chapter explains a new description of multimedia and intelligent learning objects. The authors mention the benefits of integrating multimedia content into e-learning. Then they develop the intelligent learning environments on the one hand and the pedagogical objects on the other hand. Then, they fix the new elements of their application profile; the latter is crowned with a semantic description in the form of an ontology. Finally, they detail the generation components of multimedia and intelligent learning objects.

Metadata is used to describe the entities, and to promote interoperability between the various systems. The same applies to pedagogical objects: several metadata have been developed at different levels, including the schema, the application profile and the standard. This has a positive effect on the interoperability of metadata, particularly at the syntactic, linguistic and technical levels. However, the influence is relative given the various factors hindering interoperability, namely: the multiplicity and heterogeneity of systems, the multiplicity of protocols, the multiplicity of data formats, the diversity of metadata schemas, the diversity of vocabularies, ontologies and disciplines, The multiplicity of languages ​​and the multiplicity of encoding formats.

Despite all these efforts, the problem of interoperability of pedagogical metadata persists, especially at the semantic level, which poses a problem of understanding the information exchanged between systems cooperating in the realization of a global task.

To remedy this problem, we have moved to a new description of learning objects by adding semantic and multimedia features to better communicate with other systems.
