Open worldwide machine-coded news-event metadata beginning with the GDELT 2.0 raw stream on 2015-02-18. The coordinated product comprises the 61-field Events table and 16-field Mentions table, published as 15-minute tab-delimited ZIP files and queryable in Google BigQuery. Events encode two actors, a CAMEO action, three geographies, media-coverage measures, ingest time, and first source URL; Mentions encode each article mention, extraction confidence, article position, source identity, tone, and translation metadata. It is a media-derived event index, not a verified incident-observation database. Event-table legacy coverage measures are fixed to the first 15-minute update; later discussion is emitted as new Mentions rows rather than revisions to the Event row.
