When MDN Web Docs moved from a Wiki to a new platform called Yari it did so by extracting all "documents" from a central MySQL database to individual files in a git repo, it lost a lot of the revision history from the years that MDN Web Docs was a Wiki. This repo attempts to be a historical record of those Wiki revisions.

The revisions.csv file is a chronological (descending) list of revisions created. The following revisions are filtered out:

• Same author on the same exact URL is squashed into 1

• Certain test slug prefixes like Experiment: or User_project:

• Revisions created by the mdnwebdocs-bot user

The CSV has a heading on the first row.

The URL for any revision is simply made by taking the locale and the slug and combining it like so:

https://developer.mozilla.org/$LOCALE/docs/$SLUG

Note that many of the URLs in the CSV files no longer resolve as 200 OK on developer.mozilla.org. The remaining ones hopefully resolve to redirects. But some might resolve to 404 Page not found.

The username field is identical to the same user even if that same user has changed their username in the past. E.g. if chrisdavidmills used to have the username chris back in 2013, the records for 2013 will go under his "new" username.

Any page in MDN Web Docs always has a /contributors.txt you can add to the URL. For example:

https://developer.mozilla.org/en-US/docs/Web/JavaScript/contributors.txt

That list of usernames is similar to the list in revisions.csv except their, each username is made distinct and in order of most recently touched first.

We do NOT accept pull requests to this history. This record is carefully protected to be accurate and unaltered. If you want to show your involvement, you can share the URL to the file on this GitHub repo. In fact, it's better to do that then to download the CSV file if you want to send it to a prospective employer or school application.
