Project performance record (v1)
Project performance record is one of Demiton's published registers for Australian civil construction. A project's performance summary for a period: margin, schedule and quality signals. 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.
Part of Projects in the register catalog.

- Status
- DeclaredDefined, and fills when a source produces its first record.

Use this contract
The contract is a standard JSON Schema (draft 2020-12) document, so any JSON Schema validator can check a record against it. Keywords starting with x-demiton- add Demiton's own meaning, such as units and requiredness, and validators ignore them.
