NanoCommons (nanocommons.eu/) is the nanosafety infrastructure project whose goal is to build a common data management environment across European and international nanosafety projects. It is not directly producing data itself and, thus, ERM identifiers have not been registered. However, within its role as a cross-project enabler it accepted the responsibility to develop the ERM and host it on the NanoCommons Github. Additional community support activities undertaken by NanoCommons include extending the common ontology, the eNanoMapper ontology, which has been maintained by NanoCommons in recent years . The ERM identifier aligns well with this goal as it allows nanosafety research projects to globally and uniquely refer to specific nanomaterials. NanoCommons is also driving the development of the NInChI which aims to provide the means by which specific information related to individual nanomaterials in the ERM can be added, and similarity of materials in the registry can be assessed. Furthermore, via its Transnational Access activities (www.nanocommons.eu/ta-access/) NanoCommons was responsible for guiding the data management processes of the NanoFASE project. In this way, we were able to promote the use of ERMs for the nanomaterials used within the project. The use of ERMs as a unique identifier for the project's nanomaterials was included, as a provision, in the revision and updating of the adopted Nanoinformatics Knowledge Commons (NIKC, ceint.duke.edu/research/nikc, ) data curation templates (see Figure ) and relevant guidance was included in the guides developed through the collaboration of the NanoFASE and NanoCommons projects , including the international partners Center for the Environmental Implications of Nanomaterials (CEINT) of Duke University and Team Helium LLC (U.S.A.).
