Every Collection here is a mirror that cites its true upstream source with a real checksum, and every README and AGENTS.md is written to the standard in the spec's documentation best practices, so the catalog doubles as the worked example of what good catalog documentation looks like. The Netherlands provinces Collection also mirrors its upstream ISO 19115 record as a metadata-role asset, and every code block in these docs is executed by the repository's checks before it publishes.
Agents, each Collection carries its own AGENTS.md with join keys, quirks, and tested queries, and the catalog-level AGENTS.md maps the joins between Collections.
