What do researchers, publishers, librarians, and data repository managers understand about the role of metadata in their work? Metadata is descriptive information about research resources themselves, and it provides important insights for discovering new knowledge, organizing resources, and understanding who the experts are in any field. In this comprehensive study, these constituents responded to a survey to reveal their awareness, knowledge and use of metadata. The results were analyzed and published in the peer reviewed academic journal, Quantitative Science Studies by MIT Press.
