Pattern for Local Unique Identifiers

Local identifiers in Role Ontology should match this regular expression:

Example Local Unique Identifier
0000002   Resolve
Pattern for CURIES

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

Example CURIE
Namespace Embedded in LUI
This resource has been annotated by the Bioregistry as having a potential namespace embedded in LUI. This means that you may see local unique identifiers that include a redundant prefix and delimiter (also known as a banana) and therefore look like a CURIE. For Role Ontology, the banana looks like RoleO_. Therefore, you may see local unique identifiers for this resource that look like RoleO_0000002 (instead of the canonical form 0000002) and CURIEs for this resource that look like RoleO:RoleO_0000002 (instead of the canonical form RoleO:0000002). The Bioregistry will automatically strip off the banana when standardizing local unique identifiers and CURIEs.

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 0000002 is used to demonstrate the providers available for Role Ontology. A guide for curating additional providers can be found here.
