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:

Example Local Unique Identifier
sov:WRfXPg8dantKVubE3HX8pw   Resolve
Pattern for CURIES

Compact URIs (CURIEs) constructed from Decentralized Identifier should match this regular expression:

Example CURIE
MIRIAM Namespace Embedded in LUI
The legacy MIRIAM standard for generating CURIEs with this resource includes the namespaceEmbeddedInLUI as true. The actual part that gets prefixed before the local unique identifier regex, otherwise known as the banana, is did:. Therefore, you might see local unique identifiers written out as CURIEs.

The metaregistry provides mappings between the Bioregistry and other registries. There are 2 mappings to external registries for did.

Registry Name Metaprefix External Prefix
Identifiers.org miriam did
Name-to-Thing n2t did

Providers are various services that resolve CURIEs to URLs. The example CURIE did:sov:WRfXPg8dantKVubE3HX8pw is used to demonstrate the provides available for did. Generation of OLS and BioPortal URLs requires additional programmatic logic beyond string formatting.
