In the field of Interactive Learning Environments (ILE), most of the existing repositories or those under development are devoted to Learning Objects (LO). These objects have mainly static or dynamic content and are designed to be used as such in an ILE. As far as we know, repositories where ILE designers can retrieve and re-use software components do not seem to exist. Therefore, we elaborated and implemented a repository to store software components that could be used to build an ILE. This objective has lead us to propose a specific metadata schema, named LSCM (Learning Software Component Metadata) to describe these software components. It is based on LOM for learning aspects and on BIDM (Basic Interoperability Data Model) for software aspects. In this paper, we first classify software components in four categories, according to their roles in the ILE construction. Then, we describe the main differences between LSCM and LOM. Finally, we describe the repository itself.
