Methods and Tools for Building Open Systems of Scientific Research Support

The article is devoted to the problems of building an integrated environment within the project implementation of the development of open science in Ukraine. To ensure the aggregation of metadata, it was necessary to conduct a study to identify modern methods of metadata harvesting. Since the solution to this problem involves using ready-made solutions, there was a review of the tools that allow the achievement of the project's goals. Therefore, a detailed comparative review was carried out, as well as methods for improving the semantic integration of information for the protocol will be proposed for OAIPMH.
