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 None:did:sov:WRfXPg8dantKVubE3HX8pw (instead of the canonical form None:sov:WRfXPg8dantKVubE3HX8pw). The Bioregistry will automatically strip off the banana when standardizing local unique identifiers and CURIEs.
Metaregistry Decentralized Identifier

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.

Providers

Providers are various services that resolve CURIEs to URLs. The example CURIE None:sov:WRfXPg8dantKVubE3HX8pw is used to demonstrate the provides available for this resource. Generation of OLS and BioPortal URLs requires additional programmatic logic beyond string formatting.
