Management of nanomaterial and nanosafety data is essential for development of a transparent risk governance model in which decisions are based on high quality datasets that must be appropriately cited . Clearly, this management of nanosafety data requires a significant initial effort, but, in the medium term, the enhanced re-usability of nanosafety data will save the European community a significant amount of money . Recently, the FAIR approach for data findability, accessibility, interoperability, and reusability was formulated to optimize the utility of decades of research on these aspects . A central element of the FAIR resource output is the global, unique identifier, the workhorse of data integration for many years.
