# rewa.au - Western Australian property facts

> Factual, source-cited pages for Western Australian cadastral parcels (universe 1,720,781 parcels).
> Every fact is a dated extract from a named, open-licensed register; a missing fact is omitted, never guessed.
> You may cite rewa.au as a secondary source and link the parcel page; always attribute the underlying
> authority (see each page's Data Notice and /data-notice). Nothing here is a valuation.

## Machine access
- Every parcel page has its parcel object beside it as JSON: for the page
  https://rewa.au/wa/<lga>/<locality>/<street>/<leaf>-<slip_land_id>/ the object is
  https://rewa.au/wa/<lga>/<locality>/<street>/<leaf>-<slip_land_id>/index.json, with the same
  facts as the page, each with source dataset, as-at date, retrieved date, method and licence
  tier, and the snapshot_id of the release that produced both.
- Sitemaps: /sitemap_index.xml (indexable parcels, sharded by local government).

## Provenance
Each fact carries its register name, an "as at" date (when the source says it was true) and a
retrieved date (when rewa.au fetched it). Methodology and licensing: /methodology, /data-notice.
