Site bore reference
Site bore reference is one of Demiton's published registers for Australian civil construction. Borehole records referenced for a site. 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.
- Register ID
site_bore_referenceUse this name to ask for the register. The API calls it a shelf ID.- Each record is
- A stateThe current value of something, replaced when it changes.
- Status
- DeclaredDefined, and fills when a source produces its first record.
- Data
- OrganisationPrivate to each organisation's own workspace.
- Version
- v2 (2.0.1)Current version.

Fields
18 fields: 9 required, 9 optional.
Required
Every record carries these fields.
- sourceText
The register and vintage the answer was resolved from (e.g. the NGIS NSW extract)
Example:
Queensland Groundwater Database- contentText
One sentence stating the resolved answer.
Example:
3 registered bores within 500 m of the Cherbourg Water Tr…- projectText
The tenant project whose site coordinate the answer is about.
Example:

The search radius the counts and distances were computed at.
Example:
500- horizontal_datumText
The horizontal datum (and, where frame-based, the realisation) the site coordinate was expressed in.
Example:
GDA2020- bores_within_radiusWhole number
Number of registered bores inside
radius_mExample:
3- nearest_bore_distance_mDecimal number
Distance from the project site coordinate to the nearest registered bore within the radius.
Example:
210.5- nearest_bore_rock_depth_mDecimal number
Shallowest
depth_top_mof an interval whoseMajorLithCodeis in the rock allowlist, in the nearest logged bore; null means no rock evidenced, and null is a first-class answer.Example:
18.2- logged_bores_within_radiusWhole number
How many of those carry a lithology log.
Example:
1
Optional
Present when the source system records them.
- datum_epochText

The code list/edition the lithology code belongs to (NGIS
MajorLithCode; AS 1726:2017 / AGS 4.2 / DIGGS for other sources)- nearest_logged_bore_idWhole number
The source register's
bore_idfor the nearest logged bore.Example:

Total drilled depth of the nearest logged bore.
- nearest_logged_bore_distance_mDecimal number
Distance to the nearest bore that carries a log.

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.
