International Classifications of Diseases

Mappings from records in Bioregistry to external registries comprises the metaregistry. This resource has 5 mappings to external registries with 5 unique external prefixes.

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 402558626 is used to demonstrate the providers available for International Classification of Diseases, 11th Revision (Foundation Component). Some providers may use a different example, which is displayed in the table below. A guide for curating additional providers can be found here.

Additional providers curated in the Bioregistry are listed here. These are typically inherited from Identifiers.org or Prefix Commons, and need extra curation.
