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 0000630 is used to demonstrate the providers
available for Plant Trait Ontology. Some providers may use a different example, which is displayed in the table below.
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.
