Metadata plays a key role in the scientific publication and dissemination process. It is only through metadata and identifiers that each contribution, from research data to article publication and beyond, becomes findable, accessible, interoperable and reusable. Persistent identifiers (PIDs) and their metadata are the backbone of scholarly communications, since only through them can the promise of sustainable access to research information be realized. This presentation will highlight the importance of open metadata in scholarly communications to recognize a wide range of contributions to science and as a way to build trust in research. We will also discuss the need for collaborative, community efforts to improve metadata creation and dissemination. Examples of organizations and researchers using open metadata will be presented.
