This is my understanding of it...
ABS is the percentage of damage that an armor type absorbs. For cloth its zero, for leather 10%, studded 19%, Chain 27%, Plate 34%. Damage from melee attacks are basically reduced by the abs %, I think this happens before other factors like resists are applied but I am not sure about that.
AF is your armor factor rating. Its also factors into how much damange you take, higher AF is better and will reduce melee dmg, but I am not sure exactly how the damage calculation takes AF into account.
