Electronic Passport as the Basis of the Digital Twin

During the process of decision support system development there is a problem associated with the heterogeneity of the data in terms of relevance, quality and completeness of the research objects description. The solution to this problem is digital twins based on data lake technology implementation. The aim of the work is to create a prototype of an electronic passport (e-passport) of materials as the basis of their digital twin. The digital twin is to contain a set of data on the composition, structure, calculated and experimentally measured properties, participation in the composition of chemical reactions, constructed models and "structure-property" patterns as well. It is proposed to combine the information on a specific material or compound into an information structure — electronic passports of the research object. At the same time, it is advisable to consider the electronic passport as a comprehensive description of the object, including information about the static and dynamic parameters of the atomic-molecular system of the research object. The e-passport as an information object gives a systematic data on the composition of a substance, structure, calculated and experimentally measured properties, the participation of elements in the composition of chemical reactions, constructed models and "structure-property" patterns, thus acting as a generalizing tool convenient for users to present information available in the database of digital twins of materials.
