OPERAS Metrics Service: Visualising usage of Open Access monographs

This presentation introduces the OPERAS Metrics Service, a platform that visualizes usage data for Open Access monographs. The service collects and normalizes information from distributor and publisher platforms, stores it in a centrally managed Metrics Core Database, and delivers it to publisher websites through a customizable display widget. The talk explores key technical challenges—such as data fragmentation, identifier inconsistencies, varied counting methods, and data quality issues—as well as ethical concerns including equity, context blindness, and transparency. It shows how OPERAS Metrics addresses these challenges by offering an open-source solution with transparent data processing and user-friendly display widget. The presentation highlights the ways in which OPERAS Metrics supports the needs of publishers, researchers, distribution platforms, research institutions, universities, and funding agencies seeking reliable and reproducible statistics in the context of Open Science.
