Information technology of preservation and virtualization of material heritage of the culture objects

. The mechanisms of preservation and presentation (updating) of objects of material cultural heritage used in museum organizations are evaluated. Classification of museums by profile is proposed. A new approach has been developed for three-dimensional virtualization of cultural heritage objects of various structures, which is distinguished by the most realistic representation of the object's visual appearance, as well as the introduction of an array of detailed information about it from the library, archival, museum and other information funds. It is shown that the information resource of a real-life museum and the “virtual” museum are various informational entities. A technology for combining various cultural heritage structures into a single information array, with the provision of interactive access to information about objects for a wide range of users, has been proposed. Analytical and procedural models have been developed for the formation of the information array and three-dimensional modeling of objects of tangible cultural heritage, on the basis of which a conceptual model of an information system is built. The information array is presented in 17 tables that make up the database entities. In total, an organizational and information technological mechanism for the preservation and virtualization of the objects of the material and cultural heritage of various structures was developed and introduced.
