Pattern for Local Unique Identifiers

Local identifiers in Enzyme Commission Code should match this regular expression:
^\d{1,2}(((\.\d{1,3}){1,3})|(\.\d+){2}\.n\d{1,3})?$

Example Local Unique Identifiers
1.1.1.1   Resolve
2   Resolve
2.3   Resolve
2.3.1   Resolve
2.3.1.n12   Resolve
3.1.26.n2   Resolve
Pattern for CURIES

Compact URIs (CURIEs) constructed from Enzyme Commission Code should match this regular expression:
^eccode:\d{1,2}(((\.\d{1,3}){1,3})|(\.\d+){2}\.n\d{1,3})?$

Example CURIEs
eccode:1.1.1.1
eccode:2
eccode:2.3
eccode:2.3.1
eccode:2.3.1.n12
eccode:3.1.26.n2

Providers

A provider turns a local unique identifiers from a resource into a URI. Many providers are also resolvable as URLs (i.e., they can be used in a web browser).

The local unique identifier 1.1.1.1 is used to demonstrate the providers available for Enzyme Commission Code. A guide for curating additional providers can be found here.

Extra Providers

Additional providers curated in the Bioregistry are listed here. These are typically inherited from Identifiers.org or Prefix Commons, and need extra curation.
