In this article we present the MIRTO platform -under development at the University Stendhal of Grenoble- and how it addresses common flaws of CALL software. This platform led to another project: the creation of a pedagogically indexed text base. We introduce here the notion of pedagogical indexation, and confront the particular case of pedagogical indexation for language learning with the existing pedagogical resource description standards, before proposing leads towards the implementation of the former.
