Workflows are configurable per domain and asset type; a marketing tag and a finance KPI should not need the same approval weight.
Consumers can suggest but not publish. Suggestions are cheap and are the main source of curation volume; publication stays with the accountable role.
Certification is an owner action with an expiry. Metadata that nobody re-certifies is metadata nobody is standing behind.
Service levels
Unclaimed tasks escalate to the domain owner after 5 working days.
Certification expires after 12 months and the badge degrades rather than disappearing silently.
Coverage — assets with an owner and a description — is reported per domain monthly (view 18).
Risk
Stewardship is the resourcing risk of the whole programme. If domains do not staff it, the platform degrades into technical metadata only, which is a search tool, not governance.
