The eNanoMapper project ( is creating a pan-European computational infrastructure for toxicological data management for ENMs, based on semantic web standards and ontologies. > This ontology is an application ontology targeting the full domain of nanomaterial safety assessment. It re-uses several other ontologies including the NPO, CHEMINF, ChEBI, and ENVO.

Pattern for Local Unique Identifiers

Local identifiers in eNanoMapper Ontology should match this regular expression:

Example Local Unique Identifier
8000221   Resolve
Pattern for CURIES

Compact URIs (CURIEs) constructed from eNanoMapper Ontology should match this regular expression:

Example CURIE
2015 eNanoMapper: harnessing ontologies to enable data integration for nanomaterial risk assessment.
Metaregistry eNanoMapper Ontology

The metaregistry provides mappings between the Bioregistry and other registries. There are 4 mappings to external registries for enm with 2 unique external prefixes.

Registry Name Registry Metaprefix External Prefix Curate
AberOWL aberowl ENM
BioPortal Prefixes bioportal ENM
FAIRSharing FAIRSharing logo fairsharing FAIRsharing.2gpf81
Ontology Lookup Service Ontology Lookup Service logo ols enm

Providers are various services that resolve CURIEs to URLs. The example CURIE enm:8000221 is used to demonstrate the provides available for enm. Generation of OLS and BioPortal URLs requires additional programmatic logic beyond string formatting.
