The national project ReSeed aims to offer an alternative allowing both semantic (2D sources) and physical (3D) modeling for our scientific, technical and industrial heritage; while guaranteeing authenticity and integrity of knowledge. The digital integration of heterogeneous knowledge is ambitious; the project team then demonstrated that designing a unique tool is not possible. ReSeed's proposal is one digital container of self-structured knowledge created simultaneously with the digital double of the heritage object studied. Considered as an "Augmented Historical Reality" defined by a virtual tool instead of the usual "paper" procedures, ReSeed nonetheless remains a tool for asset decision support.
