Does Safari browser history DB contain transition type?
Checked with my history, the origin column seems to show the origin of the database entry. In my case it was 0 for the MacBook running Safari (where I checked the contents of History.db and 1 for history entries from my iPad (history gets synced over iCloud). The generation column might have something to do with "generations of histories". I found the entries current_generation and last_synced_generation in the metadata table, which would suggest it having something to do with syncing the history to the cloud. This is only an educated guess though. As for attributes I'm still kind of stumped.
