 Axioms are basic statements of an ontology and also the main component, they state what is true in a domain.
 It is possible to have axioms for classes, properties, datatype definitions, assertions and annotations.

-Description Logic
+Description logics (DL) is a family of formal knowledge representation languages. DLs are used in artificial intelligence to describe and reason about the relevant concepts of an application domain (known as terminological knowledge). The Web Ontology Language [OWL] and its profile is based on DLs. The DL expressivity gets the human readable name of this metric.

 ==Annotation Axioms==
 An OWL ontology contains a set of annotations. These can be used to associate information with an ontology — for example the ontology creator's name.
 Each annotation consists of an annotation property and an annotation value, and the latter can be a literal, an IRI, or an anonymous individual.

 Individuals are the instances of the classes, so they represent the actual object of the domain.
 There are two types of individuals: named- and anonymous individuals.

 In OWL exists a thing-class, which is a universal class, so every user defined class is a subclass of the thing-class.
 The corresponding metric count the classes, including the thing-class, to create a view on the quantity of classes.
