Pattern for CURIES

Compact URIs (CURIEs) constructed from Enzyme Nomenclature should match this regular expression:

Example CURIE

The metaregistry provides mappings between the Bioregistry and other registries. There are 6 mappings to external registries for eccode.

Registry Name Metaprefix External Prefix
FAIRSharing FAIRSharing logo fairsharing FAIRsharing.q1fdkc
Gene Ontology Registry go EC logo miriam ec-code
Name-to-Thing Name-to-Thing logo n2t ec-code
Prefix Commons prefixcommons EC
Wikidata Property Wikidata Property logo wikidata P591

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