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.

欧洲材料登记处：（未公开的）纳米材料的全球唯一标识符

纳米材料和纳米安全数据的管理需要在 FAIR（可查找性、可访问性、互操作性和可重用性）原则下进行，这需要为每种纳米材料提供唯一的全球标识符。现有标识符可能并不总是适用或足以明确识别特定研究中使用的特定纳米材料，导致在研究项目沟通和报告中使用文本描述。为了确保内部项目文档以后可以与特定纳米材料的公开发布的数据和知识，甚至与该项目中使用的特定批次和纳米材料变体相关联，提出了一个新的标识符：欧洲材料标识符登记处。我们在这里描述这个新标识符的背景，包括由 FAIRSharing、identifiers.org、Bioregistry 和 CHEMINF 本体定义的 FAIR 互操作性，并展示它如何补充其他标识符，例如 CAS 编号以及正在进行的将 InChI 标识符扩展到涵盖纳米材料的努力。我们提供了其在 H2020 资助的各种纳米安全项目中的使用示例。
