Obtaining reusable data in the nanosafety domain, especially when integrating it from multiple sources, can be better achieved when the metadata complies with a community standard that enables harmonized assessment of data reusability for a particular use case. Moreover, the data should be findable, and its metadata should be expressed in a format that facilitates both the discovery and assessment by humans and machines. In the nanosafety domain, minimum reporting standards were proposed by several teams as a way to facilitate cross-comparison of data and its interpretation , support risk assessment , assess data completeness , achieve reproducible research , or investigate the environment and health impact of nanomaterials . All those MRS developed for different purposes constitute the nanosafety community standards in the broad sense. Making the nanosafety community standards available for FAIR reusability assessment (subprinciple R1.3) in the form of maturity indicators would substantially increase the usefulness of those standards on several levels: 1) provide a reference for researchers and data makers on how to make their data reusable and embed those recommendations within their data workflows and lab notebooks; 2) Re-annotate existing datasets with metadata that complies with the community standards maturity indicators. Thus, already published data would be exposed to all the beneficial applications (see Discussion) of reusability assessment; and, 3) develop software agents that use the nanosafety MIs to assess datasets' reusability for different use cases.
