./use-cases/ folder is meant to contain the different use cases that will compose the ontology.
A use case may be compared to a motivating scenario except while a motivating scenario is meant to determine which terms are needed to be implemented within the current iteration, a use case is meant to show the current description abilities at a given ontology version without implementing any new term.
Each folder directly in ./use-cases/ is considered a use case.
Any .ttl file found int the hierarchy of this folder is considered a module.
