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”
