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 _space_group_symop.operation_xyz is used to demonstrate the providers available for Crystallographic Information Framework. Some providers may use a different example, which is displayed in the table below. A guide for curating additional providers can be found here.
