# 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 ActivityPub actor IRI that addresses a federated-social account (Mastodon, Lemmy, PeerTube) across the fediverse — the protocol identifier other servers resolve to interact with it.

Avoid when

• Avoid for the display handle (use gmeow:accountName) and for the Nostr identity layer (use gmeow:nostrPubkey / gmeow:nip05); the actor IRI is the ActivityPub-specific endpoint, not a generic homepage.

How to use

• Carry the actor IRI as an xsd:anyURI on the OnlineAccount; keep the service it belongs to on gmeow:accountService and the human handle on gmeow:accountName so each identifier role stays distinct.
