Identifier Standards
Pattern for Local Unique Identifiers

Local identifiers in MoonProt should match this regular expression:
^\d+$

Example Local Unique Identifier
4   Resolve
Pattern for CURIES

Compact URIs (CURIEs) constructed from MoonProt should match this regular expression:
^moonprot:\d+$

Example CURIE
moonprot:4
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 4 is used to demonstrate the providers available for MoonProt. Some providers may use a different example, which is displayed in the table below. A guide for curating additional providers can be found here.
