# Worked example: online accounts, decentralized identity, and P10. An
# agent gmeow:holdsAccount one or more gmeow:OnlineAccounts, each on a
# gmeow:OnlineService. Decentralized identities are first-class: a Mastodon
# account carries its gmeow:activityPubActor URI, a Nostr account its
# gmeow:nostrPubkey and gmeow:nip05 handle. P10 (suppression, never deletion):
# when a service shuts down, its account is kept as gmeow:accountStatusHistorical
# — the record persists, it is not erased.

Usage Advice

Use when

Use for the Nostr public key (npub or hex form) that cryptographically identifies a decentralized-identity account, independent of any single relay or service.

Avoid when

Avoid for the human handle (use gmeow:accountName) and for the domain-verification identifier (use gmeow:nip05); the pubkey is the cryptographic identity, not the display name or the verification.

How to use

Carry the pubkey as a literal on the OnlineAccount and pair it with gmeow:nip05 when a domain verifies it; treat a pubkey that links to a real person as sensitive via gmeow:hasSensitivity.
