A research area registry is a database or system that categorizes and organizes different fields of research or disciplines. It serves as a tool for researchers, institutions, and funding organizations to identify and classify specific areas of study, helping to facilitate collaboration, resource allocation, and the dissemination of research findings. Research area registries typically include a hierarchical structure that allows for easy navigation and mapping of related fields, as well as metadata such as keywords, descriptions, and associated researchers or organizations. They can also provide insights into emerging trends and areas of interest in the global research community.
