Site requisitions

Site requisitions is one of Demiton's published registers for Australian civil construction. Site requisitions for materials, plant or resources, 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.

Part of Projects in the register catalog.

Which Assignar requisition form template produced the row — provenance for a title-pattern match that can sweep renamed forms.

Defined by each organisation

Their contents come from the organisation's own forms or systems, so they differ between organisations.

requested_itemsList

The plant/equipment and staff the requisition asks for, as an itemised list rather than one top-level key per named person or machine.

custom_questionsGroup of fields

The residual tenant form answers, including the form's own approval/authorisation answers.

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.
