An additional 196 ERM identifiers are used in a data extraction project in collaboration with the SbD4Nano project (www.sbd4nano.eu/). Data was extracted for all nanomaterials mentioned in 25 papers that were previously analyzed for adverse outcomes . This resulted in 196 nanomaterials with matching ERM identifiers. The nanomaterials and their Molecular Initiating Events (MIEs) are captured in an RDF schema and annotated using standard metadata vocabularies and specialized ontologies (manuscript in preparation). This way, the identifiers are linked to a nanomaterial name, the reference from which the data is extracted, the PhysChem properties of the nanomaterial as reported in the publication and the MIE, Key Event and/or Adverse Outcome Pathway reported for that nanomaterial. This exemplifies how the ERM identifier can be used to discuss nanomaterials in a FAIR way.
