Health screening
Health screening is one of Demiton's published registers for Australian civil construction. Fitness-for-work and fatigue screening results, by worker and project. Demiton keeps it current from the systems a contractor already runs and publishes the record's shape as a versioned JSON Schema, so the same question works whichever system produced the record.
