Musicbrainz datadump multiple artists

Hello, I have just downloaded the main datadump from the musicbrainz website, and I am trying to find out how the multiple artists on a track/recording are handled. I have tried looking at the documentation file but I am not sure what to open it with as it is a bit unreadable in notepad lol. My goal is to make an erdos number program for musicians, so if you think these files are the wrong place for that please let me know. Thank you!

See Artist_credit and artist_credit_name in database schema.
