Abstract
The PNER (1999-2001), implemented by the House of Human Sciences and supported by the Ministry of National Education, Research and Technology, analysed changes in usage, proposed a reflection on standards and worked on the legal issue in the field of ICT for teaching and research. Teaching and research are at the origin of the production of many public data. As part of its tasks, the Ministry of National Education or the Ministry of Research collect and/or process and/or disseminate extensive information. The information or data envisaged in this study can be classified as public in the sense that it is produced (collected and/or processed and/or disseminated) as part of the public service activity. The data produced by the ministries fits more broadly into the issue of the dissemination of public data. They now represent an economic wealth. Economic but also social wealth. It is therefore from this confrontation between these values, economic and social, that the full benefit of the study arises. The conditions for production really determine the dissemination policy. This is why, in a first chapter, we will consider a typology of teaching and research data. We will then consider the actual dissemination.
