The article analyzes the specifics of modeling information resources (IR). The concept, essence and role of IR, their content features and properties, such as massiveness, systematization, fundamental and material value, are revealed. The importance of creating a unified system for the use of IRs for their effective use, regardless of the type, is indicated. The concept, content and general principles of the modeling process are considered, the process of IR modeling is analyzed. The role of IR in modeling the subject area of the information system is determined, the general boundaries of their application are indicated, such as the static nature of models and the absence of modeling of behavioral aspects. The conditions for the successful choice of the IR modeling technology and the group of object properties are given, which are used to identify the IR properties from the standpoint of semiotics. The key stages of IR modeling, the essence, specificity and results of each of them are identified. It is indicated that at the stage of conceptual (descriptive) modeling, a concept is being developed that covers the structure, principles, basic properties and the course of building an IR, tools and methods of forming a system; at the stage of formalized modeling, the essential properties of IR are displayed by graphic and / or mathematical character to categories, at the stage of physical modeling - an experimental check of the operability and adequacy of the created RR models by developing a physical RR model, which is a combination of the structure, means and methods of the reduced full-scale display of RR. It is noted that the modeling of IR is of particular importance in multilevel controlled systems, since it acts as a factor for reducing uncertainty in solving problems of the formation, improvement and use of heterogeneous IR.
