Résumé
This article aims to define the concept of "environmental memory" within the "Zones Ateliers" of the Environment, Life and Societies Program of the CNRS (French National Committee for Scientific Research), and to present the stakes of its conceptual modelling and the main strategies to develop. The "environmental memory" is defined as the sum of the explicit, persistent and structured representations of data, knowledge, models and scientific know-how, attached to an anthroposystem, in order to facilitate its access, its sharing and its re-use. Its modelling, whose realisation is currently under process, makes it possible to identify the system to be abstracted and formalises the data to be acquired, the tasks to be realised, the methods of problems' resolution to be applied during a research project management. The implementation techniques are mainly based on Internet technologies, Geographic Information Systems, Relational Database Management Systems, Knowledge-Based and Resolution Problems Systems.
