OpenAIRE is a network of 50 partners across Europe that provides an open science e-infrastructure for research analysis and impact measurement. It integrates data from literature repositories, journals, funding information, and other sources to create a single research information system. OpenAIRE also offers services for monitoring research outputs and impacts, including aggregated metrics, advanced analytics, and continuous policy monitoring. The goal is to provide policymakers and funders with tools to assess the impacts of open access and open science policies.
