The Gov4Nano project (www.gov4nano.eu/) recently established the GO FAIR implementation network, AdvancedNano (www.go-fair.org/implementation-networks/overview/advancednano/), which will support implementation of the FAIR principles in nanosafety data management systems. To achieve the overarching aim to disseminate and collaborate on solutions for increasing FAIRness of nanosafety data, the project is working on a set of six case studies that demonstrate findability and accessibility (case study 1), interoperability (case study 2), and reusability (case studies 3 to 6) of nanosafety data. Case study 1 is focused on implementation of persistent identifiers and aims to develop strategies for the community to actively use such identifiers, including the ERM identifiers, focusing on barriers and incentives for uptake of solutions. Case study 2 focuses on the use of electronic laboratory notebooks to support increased implementation of workflows to standardize data formats and harmonize metadata annotation, including ERM identifiers, related to work developed in NanoCommons on the data life cycle and metadata requirements and needs at all stages of the nanosafety data lifecycle . Case studies 3 to 6 aim to demonstrate reuse of omics, ecotoxicological, genotoxicity, and human occupational exposure data, respectively. Each case study will consider curation strategies involving implementation of ERM identifiers. For example, the omics case study is focused on providing reusable nanosafety-relevant omics data as input for tools and models in the Nano Risk Governance Portal, supporting the Nano Risk Governance Council developed in concert with the two other governance projects (RiskGONE and NanoRIGO). Reuse of omics data is highly dependent on integration with other types of data, such as physicochemical and exposure data. Implementation of the ERM identifiers supports this type of integration across diverse types of data and eventually enables interoperable reuse of relevant high-content omics data .
