Pattern for Local Unique Identifiers

Local identifiers in PIR Superfamily Classification System should match this regular expression:
^PIRSF\d{6}$

Example Local Unique Identifier
PIRSF000100   Resolve
Pattern for CURIES

Compact URIs (CURIEs) constructed from PIR Superfamily Classification System should match this regular expression:
^pirsf:PIRSF\d{6}$

Example CURIE
pirsf:PIRSF000100

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 PIRSF000100 is used to demonstrate the providers available for PIR Superfamily Classification System. A guide for curating additional providers can be found here.
