Slot: Source Access URL (source_access_url)

Landing-page URL for the dataset (not a download link, which rots).

Tier: recommended

Why this slot matters

A stable landing page is how future users actually reach the data; a raw download link rots when files are reorganised, leaving the record pointing nowhere.

In plain terms

The dataset's home page on the web — the front door where you can read about the data and find the download options — rather than a direct file link that stops working when files move.
