SoVisu is a flexible and open device created to accompany the community of an institution to the Open Science (OS) by providing it with the guiding instruments of its management, while allowing to map the expertise of the researchers, to facilitate the self-archiving and to appreciate the quality of the indexation. This device takes source on HAL to be registered in the ecosystem of the SO on the user side by giving the possibility to the researchers to align their identifiers, to qualify/verify and supplement their bibliographical data, their fields and their "expert" keywords. For a laboratory, on the governance side, the same principles and previous functions by aggregations, extractions of the production in HCERES format and other dynamic and interactive cartographies. The aggregations then allow for operation on bibliographic data verified and validated by the researchers.
