# 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 an agent's identity-bearing account on an online service — a social profile, code-forge login, email account, or decentralized identity — modelled as the information object that carries the handle, service link, and account status.

Avoid when

• Avoid for the agent itself (use gmeow:Agent / Person) and for the service or platform the account lives on (use gmeow:OnlineService); the account is neither the person nor the platform but the held identity-object linking the two.

How to use

• Type the account as OnlineAccount, link the holder with gmeow:holdsAccount, the platform with gmeow:accountService, the handle with gmeow:accountName, and the usage state with gmeow:accountStatus; mark sensitive identifiers with gmeow:hasSensitivity so projections can withhold them.

Examples

• ex:lillithMastodon a gmeow:OnlineAccount; gmeow:accountService ex:fosstodon; gmeow:accountName "lillith".
