Ownership in the default catalog is modelled with team resources. The owning team is responsible for contract changes, service reliability and documentation freshness for its resources.

Ownership rules

The owner listed on the producing resource owns the contract. Consumers can request changes, but producers decide versioning and rollout.

When a flow spans multiple teams, the team owning the orchestrator is responsible for keeping the flow page current. For checkout, that is Ordering PlatformOrdering PlatformTeam•vOwns the Ordering domain — turning a checked-out cart into a confirmed order.View docs.

Every resource page should explain responsibility, owners and major contracts. These custom docs should explain cross-resource narratives that do not belong to one resource.
