The figure below provides an overview on OWL classes and object properties present in the vocabulary. For simplicity, inverse object properties and some subclasses are not shown. Additionally, a distinction between \"essential\" OWL classes, that are required for the description of data sources, and \"optional\" classes, which provide additional non-necessary features, is being made.
