Tags attached to the version.

Note: Tags can be added to an article to signify that this revision was part of a campaign, specific project-run initiative, tracked edit type, or other Wikimedia event.

Example: "Sample comment describing reason for revision"

Comment attached by the editor to the latest version. This returns a parsed response.

Note: When a revision is saved, the editor has the ability to leave a comment describing why they created this revision.

 "mobile app edit",
 "android app edit"

Was this change considered minor by the editor.

Note: When a revision is saved, the editor has the ability to mark whether this is a minor revision. Although this option is set by editors themselves and can lack consistency, minor revisions are typically grammar corrections and are less critical to review.

Example: false

Was this revision marked stable by the project community.

Note: Depending on the project, there are different community approaches to having administrative approval on revisions as they happen. This will reflect whether or not the revision has been approved. While false does not mean this is a vandalized article, true is typically a good indicator that this is a good revision.

Example: false

This object contains version scores calculated as part of Wikimedia’s ORES project.

There are two models included:

• damaging: predicts whether or not an edit causes damage
• goodfaith: predicts whether an edit was saved in good faith

Included in these models are three data points:

• Prediction
• Probability true
• Probability false

Available for projects supported within Wikimedia Foundation’s ORES APIs
