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 0000001 is used to demonstrate the providers available for Basic Formal 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.
