I added three properties to type Film on Sandbox with several supporting types that cover:
1. Production companies -- this is a simple relationship between type Film and type Production Company.
2. Distributors -- This connects type film to type Film Distributor through a Compound Relationship Type (CRT) called Film-Film distributor relationship which includes properties for the year of distribution, the film cut type (director's, special edition) and the medium of distribution (Theatrical, VHS, DVD).
3. Other film companies -- This connects film to companies other than production companies and distrubutors (which are normally accorded a special status, so therefore singled out.) Type Film here connects to "Film Company" via a CRT called "Film-Film company relationship" which includes properties for the role or service provided by that company and which film cut type it contributed to.
Note here that I'm using a couple of new naming conventions. First, I'm suggesting the use of "CRT" for Compound Relationship Type instead of CVT or Compound value Type. This distinction will become increasingly important in the upcoming months as we bake a deeper distinction between these patterns into MQL.
Second, I've named these CRTs with a new convention that describes it as a relationship between two types. For example, "Film-Film company relationship" connects the types Film and Film company.
Here's a film topic example that includes all three ne properties filled out:
