Introduction
An effective solution to the tasks of preserving and accessing electronic documentation requires software applications, namely an electronic archive within the information management system of the organization.The information management system is a digital object-control and management system, as well as facilitates the planning and control functions of the enterprise.The main tasks of the IMS are the preservation, processing, analysis, use, and protection of information.The main avocation of this system is to simplify the work of man, to correct major mistakes that arise during work and to increase the quality of work.
The object of research is the information management system for the fund of the Scientific and Technical Library ONAFT.At the moment, despite the development of information technologies, most scientific papers, articles, editions and educational materials are stored in paper format, which complicates the search for the necessary information.In order to facilitate the preservation, access and reproduction of information, an institutional repository was developed which is freely available.

Problem statement
At the present stage of development of Ukrainian science, the disciplines that are exploring informational activity occupy a prominent place, which is based on various documentary forms.In the first place, they include a bibliography, library science, bibliography, which are united in one scientific specialty, which allows to comprehensively consider the problems of the development of these scientific disciplines.Since the main objective of library activity is the formation of a library and information space, which involves the collective creation and use of shared resources, therefore, in today's conditions, there is a need to strengthen the information interaction between libraries on the basis of promising information technologies and standards.
At present, information technology plays a key role in the process of obtaining, storing and disseminating information and knowledge, and is one of the most important tools for strategic development of libraries.Based on information technologies in libraries, new services and services are being developed, a new library environment is being created, staffing is being expanded.That is why the study and implementation of information technology in the work of libraries is one of the most important directions of modern library activity.
The electronic library, as an equal module of the information system, is directly interacting with the information repository.Getting the necessary information from the institutional repository software significantly reduces the number of library links required with the databases of the HIE departments.

Purpose and objectives of the study
The main goal of this project are to create a single electronic resource, namely, an institutional repository for the conservation of scientific works, articles, media, patents, educational objects, annotations and dissertations that are freely available for both HIE employees and for the world the community.To reproduce the set goal, a number of tasks were solved, namely: detected and investigated industry implementation; analyzed several existing analogues; selected methods and implementation environment; identification and elimination of probable deficiencies.The object of research is the management information system for the library fund STL ONAFT.At the moment, despite the development of information technologies, most scientific papers, articles, editions and educational materials are stored in paper format, which complicates the search for the necessary information.In order to facilitate the preservation, access and reproduction of information, an institutional repository was developed which is freely available.

Methods and materials of research
To design the project, an integrated software development environment was chosen -IntelliJ IDEA, the object-oriented programming language was chosen in Java in the main language.The software was developed on the JavaEE platform, which is suitable for creating enterprise level applications.In developing the project, the automation tool for working with Apache Maven software projects was used to automate the assembly of the project based on their description of the structure in the POM files, and the Spring framework, which provides the solution to most tasks when developed on the JavaEE platform.A Hibernate library was also used to solve object-relational mapping tasks.
To play the institutional repository, the DSpace platform was used, which is an open source software written in the Java programming language.DSpace supports a large amount of data, and records themselves are available through a web resource.
For the development of the database of the information management system, a free object-relational database management system -PostgreSQL was used.This DBMS is based on the SQL language and supports most of the standards of this language.The main features of this DBMS are highly efficient and reliable transaction and replication mechanisms, an expanded system of embedded programming languages.The main features are functions, triggers, rules, views, and indexes.
The developed software, which is the information management system for the library fund, has a client/server application classification, the three-tier architecture of which consists of the client and server parts, a relational database was created to store and access data.The presented architecture organizes the separation of application level from data management.Separate a separate program level, which focuses on the application logic of the program.Data management is carried out by the data server.
The expanded interaction of the elements is depicted in the information scheme in Fig 1.

Fig. 1 -the information schema of web-application
When a user requests a web application, the data is sent to the HTTP server via the https protocol.The server checks the domain name from the request through which it was contacted and sent through AJP protocol using the proxy tunnel to the Apache Tomcat web server.An Http server is required to distribute queries to several different web applications, since a software product, which is an information retrieval system of the institutional repository, is being deployed in the "ecosystem" of other software products of the ONAFT Scientific and Technical Library.Next, Apache Tomcat shares query with the web application.The server receives the request for any information, it is handled by the web application controller.If the request requires information from the database, then the controller accesses the DBMS, processes all the necessary information and returns the request to view the component as Java servlet pages of the file that is sent to the user.

Research results
The result of the development is the information and control system for the library fund STL ONAFT, implemented for the purpose of free access to research related to the development of a specific subject area, for further use in the educational process of HIE.
The developed software has a three-tier architecture.This architecture consists of a client, an application server, and a database management server.To interpret the created web resource, you need an application to view the created web page.The project is adaptive to various platforms, provides a multilingual interface that meets the modern requirements for a web resource.
To operate the system, there are several groups of users:  main administrators are a group of users who have unrestricted rights to use the system's functionalities and distributes rights to other users for access to different levels;  section administrators are a group of users who have unlimited rights within the specified section or sections;  collections administrators are a group of users who have unlimited rights within a particular collection or collections;  anonymous users -a group of users who have rights only to view sections, collections and their contents.
The system has an opportunity to subscribe to new collections.It's enough to be registered in the system.
