Contract link

Contract link is one of Demiton's published registers for Australian civil construction. A verified link from one of your projects to a public government contracting record. 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 Contracts in the register catalog.
