The article researches the principles of creation and assignment of a unique identifier inspireId to objects of classes in the topographic database (TDB), which is developed on the basis of the concept of model-driven architecture. The issue of automatic generation of a unique identifier inspireId and the rules of its life-cycle is researched. The goal of the work is to study the principles and requirements for the structure and assignment of a unique identifier inspireId objects of classes of TDB and the implementation of its automatic generation in SQL to provide interoperability with datasets of European Union Geospatial Data Infrastructure (INSPIRE) and EuroRegionalMap (ERM). Methods. In accordance with the general principles and requirements of the ERM to the structure of the unique identifier inspireId objects of classes of the topographic database, developed its structure for the identification of objects in the TDB “Main State Topographic Map”. The function for automatic generation of inspireId in the object-relation database management system (ORDBMS) PostgreSQL has been developed. The life-cycle rules of a unique identifier in TDB, which ensures its stability, are considered in detail. Results. The developed structure of the unique inspireId identifier and the proposed rules of its life-cycle can be used in any geospatial databases. The use of the unique identifier inspireId in the Topographic Database “Main State Topographic Map” provides a link to the Infrastructure for Spatial Information in the European Community and EuroRegionalMap datasets. Scientific novelty and practical significance. The method of assigning a unique identifier inspireId to the objects of the topographic database classes “Main State Topographic Map” is proposed, which will further provide a link to the sets of the Infrastructure for Spatial Information in the European Community and EuroRegionalMap.
