What is the purpose of an Interface in the Ontology?

• A. An Interface is an abstract type describing shared properties across multiple object types, enabling polymorphic workflows.
• B. An Interface is a concrete object instance.
• C. An Interface defines the primary key.
• D. An Interface is the dataset containing all objects.

Answer: (A)

Interfaces in the Ontology define a common contract of shared properties or capabilities that multiple object types can implement. They are abstract, describing what conforming objects must expose rather than representing a specific object themselves. This lets tooling and workflows treat different objects uniformly through the interface, enabling polymorphic behavior where a single operation can work with any object that implements that interface. For example, an interface like Persistable might require an identifier and a saved timestamp, so datasets, models, and reports that implement it can be handled by the same saving or auditing routine without caring about each object's concrete type. An Interface is not a concrete object instance, it does not define a primary key by itself, and it is not a dataset containing all objects; it is the abstract contract that several object types share.
