What it is Derived, awaiting review
This meta-model describes groups, cohorts and communities as addressable collectives: named groups with memberships and roles, rule-based statistical cohorts with their materialized snapshots, and the representation and channels that make a collective addressable as one party.
Note: First sentence of the legacy card introduction.
Why it exists Filled
Groups cohorts and communities as addressable collectives
Distinguishing features Derived, awaiting review
- It is its own model because collectives have identity, membership dynamics and spokesmanship of their own, distinct from the persons inside them and from any formal organization they may or may not become.
What robots and AI may and may not do Derived, awaiting review
Must not
- It is its own model because collectives have identity, membership dynamics and spokesmanship of their own, distinct from the persons inside them and from any formal organization they may or may not become.
Moral aspects Missing, in the backlog
Not described yet. This gap is in the card backlog.
Owners Filled
Steward
A group steward owns each community's record and its addressability; the statistics office owns cohort definitions and snapshots and guarantees that only aggregates leave the protected layer.

- world.person - members, stewards and mandate holders are natural persons referenced by identity
- world.household - cohort criteria may evaluate household attributes as counting units
- world.organization - formalized groups continue as organizations; the reference preserves continuity of the collective
- world.socialNorm - communities are the norm-holders that D9 describes

Capabilities and actions required Derived, awaiting review
- groupFormed: a collective came into existence with a name and basis
- memberJoined: a person joined a group at a chosen visibility
- memberLeft: a membership ended
- mandateGranted: the group granted a representation mandate
- mandateRevoked: a mandate was withdrawn or expired
- cohortDefined: a statistical cohort definition was fixed by its defining authority
- snapshotTaken: a cohort was materialized into counts and distributions
- groupDissolved: a collective ceased to exist
Legacy events listed as state transitions.
Hazards and failure modes optional Missing, in the backlog
Not described yet. This gap is in the card backlog.
Standards and interfaces required Derived, awaiting review
- membershipDisclosureConsent: each member's control over whether and where their membership is visible
- cohortStatisticsContract: the statistics office computes cohorts against protected data; only aggregates leave the boundary
- collectiveAddressContract: the rules under which third parties may address the collective through its channel
- publicGroupDirectory: groups, self-descriptions and channels; omits member lists entirely
- statisticalCohortView: cohort counts and distributions; contains no individual records
- stewardRoster: current representation mandates and their scopes; omits ordinary membership
Context of use required Filled
- Membership visibility belongs to each member, and every access is granted by the respective owner through S1/S2 with audit via S4.
