Summary0000817: Split FactType with 1 UC and more than 2 roles
DescriptionFacts which are properly created according to the N-1 rule, may still contain invalid modeling. Every FactType with more than 2 roles, and a single UC (non overlapping with others) over more than 1 role, is candidate to be nominalized.

Therefor the roles under the UC should be split into a seperate ObjectType.
TagsNo tags attached.

The new fco-im book, mentions on page 162 a violation of the N-1 Rule. Among the examples is "Employee on Project for Department". The N-1 rule violation is related to the UC6. However if the UC 4 is properly nominalised, there would be no need for this violation to be mentioned.

Therefor the question arises: Should we nominalise role 37+38 into "Project for Department", or consider this N-1 rule ineffective since it is in effect a binary fact, combining "Employee" and "Project for Department"?

Besides the discussion for checking this, a generic functionality could be to nominalize a group of selected roles (as long as they "match").

- A group of roles within the same facttype may be selected for nominalisation
- A group of roles in multiple facttypes, should match playedbyot's, and than could be nominalised.

Split Fact Type is now available from the menu. Precondition is that the verbalisation requires the roles under the UC to be adjacent.
