Releases

A new release follows each weekly update. Releases never change once published, so any result can be cited and checked later.

Every release

Follow new releases, corrections and withdrawals in a feed reader: the releases feed (Atom).

    Notes

How releases work

  • A release is made after each weekly update, unless nothing published would change. Its ID is its date.
  • current.json names the current release; releases.json lists them all.
  • The first release after each monthly GBIF comparison is registered with GBIF and gets a DOI. Others name the registered release they build on.
  • Releases are kept indefinitely. One with a safety or rights problem is withdrawn: its files are deleted, and it stays listed here with the reason.

Format versions

Each file names its format and version, such as county-weekly/1.0. Adding a field is a minor version and never breaks a reader. Removing or changing a field is a major version: releases then carry both versions for 6 months, announced in notes.json.
