Abstract

Management of nanomaterials and nanosafety data needs to operate under the FAIR (findability, accessibility, interoperability, and reusability) principles and this requires a unique, global identifier for each nanomaterial. Existing identifiers may not always be applicable or sufficient to definitively identify the specific nanomaterial used in a particular study, resulting in the use of textual descriptions in research project communications and reporting. To ensure that internal project documentation can later be linked to publicly released data and knowledge for the specific nanomaterials, or even to specific batches and variants of nanomaterials utilised in that project, a new identifier is proposed: the European Registry of Materials Identifier. We here describe the background to this new identifier, including FAIR interoperability as defined by FAIRSharing, identifiers.org, Bioregistry, and the CHEMINF ontology, and show how it complements other identifiers such as CAS numbers and the ongoing efforts to extend the InChI identifier to cover nanomaterials. We provide examples of its use in various H2020-funded nanosafety projects. Graphical Abstract: [Figure not available: see fulltext.].

Bibliographical note

Funding Information:
The registry contains supporting pages written in Markdown, [] hosted on GitHub ( github.com/nanocommons/identifiers ), and a central registry of materials in Turtle [] ( github.com/NanoCommons/identifiers/blob/master/registry ). The webpage was autogenerated by GitHub Pages. The European Registry of Materials Identifier was registered with FAIRSharing [] and identifiers.org []. The latter provided us with an official compact identifier structure []. The registry Turtle uses the RDF Schema specification for storing labels and types of nanomaterials as chemical substances, using the CHEBI_59999 term from the ChEBI ontology []. The registry is released to Zenodo several times a year to make the repository more FAIR. This release process is supported by the CITATION.cff in the GitHub repository.
