DIDs are an effort by the W3C Credentials Community Group and the wider Internet identity community to define identifiers that can be registered, updated, resolved, and revoked without any dependency on a central authority or intermediary.

Pattern for Local Unique Identifiers

Local identifiers in Decentralized Identifier should match this regular expression:
^[a-z0-9]+:[A-Za-z0-9.\-:]+$

Example Local Unique Identifier

sov:WRfXPg8dantKVubE3HX8pw   Resolve

Pattern for CURIES

Compact URIs (CURIEs) constructed from Decentralized Identifier should match this regular expression:
^did:[a-z0-9]+:[A-Za-z0-9.\-:]+$

Example CURIE

did:sov:WRfXPg8dantKVubE3HX8pw

MIRIAM Namespace Embedded in LUI

The legacy MIRIAM standard for generating CURIEs with this resource annotates the namespaceEmbeddedInLUI as true. This means that you may see local unique identifiers that include a redundant prefix and delimiter (also known as a banana) and therefore look like a CURIE. For Decentralized Identifier, the banana looks like did:. Therefore, you may see local unique identifiers for this resource that look like did:sov:WRfXPg8dantKVubE3HX8pw (instead of the canonical form sov:WRfXPg8dantKVubE3HX8pw) and CURIEs for this resource that look like did:did:sov:WRfXPg8dantKVubE3HX8pw (instead of the canonical form did:sov:WRfXPg8dantKVubE3HX8pw). The Bioregistry will automatically strip off the banana when standardizing local unique identifiers and CURIEs.

The metaregistry provides mappings between the Bioregistry and other registries. There are 2 mappings to external registries for this resource with 1 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 sov:WRfXPg8dantKVubE3HX8pw is used to demonstrate the providers available for Decentralized Identifier. A guide for curating additional providers can be found here.
