Cookwala / SDK et scénarios / 083

An insurer receives a device fault summary and nothing about the home

The insurer role may receive one constraint type, a summary of device faults by category, and only when the household names an insurer. The example household has no fault facet, so the insurer receives an empty list; a fault facet alone shows what the summary is derived from.

Étapes

  1. Over the example household an insurer receives no constraints; every one of the twelve facets is withheld with a reason. deriveConstraints

  2. Health facets are withheld as not allowed for the role; the firmware facet as not consented. No reason ever says what the value was.

  3. A device-issues facet on its own derives the one type an insurer may receive: counts of faults by category, no times, no household facts. deriveConstraints

Résultat

You know the exact scope of what an insurer can be offered under this profile, and that RFC-0001 lists the role as the first to be removed if a privacy review objects. Next: 084, two roles that receive nothing.
