Master inventory
The canonical catalog with every URL, destination and status is at
source/INVENTORY.md.
Updated whenever new material is captured.
Things explicitly not in the archive
- WordPress source code for openpropdata.org.uk — the site uses commercial themes/plugins; only the rendered HTML is mirrored.
- Member-confidential commercial documents — none of OPDA's internal commercial agreements with members or vendors are stored here.
- Personal data — transcripts are heavily redacted where they touch consumer information.
How to browse
The resource viewer reads any path under
source/ and renders it inline — JSON via JSON Crack, Markdown
and text as plain text in an iframe, PDFs in the browser's PDF viewer,
images natively, and so on. Pre-bundled JSON wrappers under
docs/data/resources/ let it work over file:// as
well as http://.
Sub-pages
- Document archive — every report, deck and project document, catalogued
