Actors using Learning Object Repositories are faced to a diversity of components created for specific situations. This research focused on creating a generic solution to integrate various applications and scenarios representation in the context of help to actors using LOR. The ODIS framework was developed and tested to interlink applications written in different programming languages, using shared OWL models: Explor@Graph, a Computer Supported Experimentation System, a scenario Editor and a Learning Object Repository. Models and instances are stored in a Sesame RDF database, offering many services such as import, export and query. Ontologies are used to standardize representations and models, so information can be exchanged and also to organize feedback and help in the environment. We will present how ODIS uses ontologies to transpose learning scenarios representations, to enrich them with user models and to define help.
