Pattern for Local Unique Identifiers

Local identifiers in InterPro should match this regular expression:
^IPR\d{6}$

Example Local Unique Identifier

IPR016380   Resolve

Pattern for CURIES

Compact URIs (CURIEs) constructed from InterPro should match this regular expression:
^interpro:IPR\d{6}$

Example CURIE

interpro:IPR016380

Global Biodata Coalition - Global Core Biodata Resources

The metaregistry provides mappings between the Bioregistry and other registries. There are 15 mappings to external registries for this resource with 8 unique external prefixes.

When using this resource in RDF, the following URI format should be used:

http://purl.obolibrary.org/obo/IPR_$1

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 IPR016380 is used to demonstrate the providers available for InterPro. A guide for curating additional providers can be found here.

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