In a parallel effort, the authors of this work were involved in the EU project NanoSolveIT , both leading the work package WP1 and partnering and contributing to several other work packages. The WP1 in NanoSolveIT aimed to create a knowledge infrastructure building upon previous efforts to organize and curate available nanosafety data (eNanoMapper , NanoCommons , NanoMILE 1 , NANoREG 2 , OpenTox 3 , NanoReg2 4 , caLIBRAte 5 , etc.) and to collect, FAIRify (utilizing semantic web technologies), and share data on NMs characteristics and biological interactions. This effort's main goal is to enable data sharing and reuse, ensure compatibility with existing infrastructure and APIs within eNanoMapper and NanoCommons, and integrate these datasets to maximize data exploitation for in-silico approaches and tools for nanosafety assessment. Therefore, during the NanoSolveIT project, several datasets either produced by research groups within NanoSolveIT or its partnering projects were selected for FAIRification, integration and public sharing under an open license.
