All files distributed within the frame of the Réseau Quetelet are distributed free of charge for use in research. All commercial use is therefore prohibited. The use of available files for teaching purposes is also proscribed for the majority of files.
User Licenses differ according to user status. In all cases, the user is requested to sign an obligations form. Depending on the type of file, a researcher may similarly be requested to commit to particular obligations, if required by the rules to which the producer in question is subject.
