The paper presents a method of developing digital twins (DTs) by creating special cognitive shell- metamodels that allow the creation, correction, scaling and implementation of arbitrary complexity of DTs of productions and their products. The method of cognitive matamodeling of DTs will allow to integrate the main properties of the software of DTs: 3D-modeling, accounting of functioning and dynamics of changes, management of configurations of DTs, monitoring of communication relations, calculation of mass and inertial characteristics, storage and visualization of chronicles of all operational and dynamic activities. This approach will add flexibility to the chain of interaction: human- DTs- communication channel- physical object, which in turn will eliminate the gap between the stages of development and implementation, as well as the scaling of the project. The use of metamodels can bring all parties involved in development and operation closer together in terms of time and location.
