Tender brief

Tender brief is one of Demiton's published registers for Australian civil construction. A cited brief on a tender: everything known about it and how you are placed to pursue it. 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.
