“… According to TopQuadrant CTO Ralph Hodgson, the precision of expression in semantic models—which allows organizations to model aspects of regulatory requirements and other governance necessities—is possible because the semantic model is “the model that is the most expressive thing that we have today. You don’t do that with an object model, you don’t do it in UML, you don’t do it with an entity relationship model, you don’t do it in a spreadsheet. You do it with a formalism that allows you to express a rich set of relationships between things.””
