In this work, we propose a framework for nanosafety data reusability assessment aimed at integrating several minimum reporting standards in the nanosafety domain and using them for data annotation and reusability assessment. We focused in this work on the nanosafety community standards (FAIR subprinciple R1.3) and enabled them in the form of maturity indicators for the purpose of generating machine-readable metadata and assessing web resources describing datasets for reusability for five possible applications.The work also introduced two web applications, one for easy-to-use annotation of data with metadata and the other one to enable automatic assessment of reusability of web resources describing nanosafety datasets.
