| Note: | A fact type role is fundamentally understood as a point of involvement in actualities that correspond to a fact type. Its incorporated characteristics come from the fact type - what the fact type requires of instances of the role. It is possible that two fact type roles incorporate the same characteristics, such as when a binary fact type means the same thing when roles are reversed, as in ‘person is married to person’. |
