 Introducing the open-air graph. Open-air graph is one of the largest open scholarly record collections worldwide, key in fostering open science and establishing its practices in daily research activities. Graph aims at bringing discovery, monitoring, and assessment of science back into the hands of the scientific community. It is created from open and authoritative research sources around the globe, and it uses graph database technology combining relationships between scientific products and entities. Graph includes information about research outputs, such as publications, data sets and software, citations, impact in usage indicators, funds and funders, authors, organizations, and communities. How does graph work, and how does the research ecosystem benefit? Open-air graph aggregates millions of metadata records from thousands of scholarly communication sources, trusted by scientists and open-air provide. The records are harmonized, enriched, and cleaned up. Then, a deed application algorithm identifies records that refer to the same entities and merges them. Subsequently, the records are further enriched with additional information and relevant indicators are incorporated based on external services like BIP Finder and usage counts. A finalization process improves the overall quality of the graph data. Lastly, information from the graph is indexed and accessible along the open-air services, EOSC, and third parties, creating added value services. Open-air graph is a service for content and service providers, research infrastructures, and innovators. Open-air graph is the epitome of a community-driven effort and technological advancement. We invite you to unlock the power of open science data with Open-air graph and enter a world full of opportunities.
