Abstract: “This paper presents a knowledge management experiment realized in an in high technological industry. After some definitions of project memory, related works and some critiques of existing approaches of project memory we suggest an approach based on two key guidelines : representation of both the context and the design rationale of a project for an efficient access to knowledge using the technology of the ontology field . Finally, after avoiding some of the weaknesses the existing approaches we suggest our ontology approach with is based on [1] rational approach , showing how ontology technology can effectively contribute to the conceptualization of memories projects in order to allow preserving relevant information to be used later.”
