Base Metrics comprise of simple metrics, like the counting of classes, axioms, objects etc. So it shows the quantity of ontology elements. For these Metrics we chose:

Axiom count

Axioms, regarding OntoMetrics, are relations between classes, it could descibe cardinality, value range or default-values of relations and attributes. It is also able to describe characteristics of relations like symmetry or transitivity.

Logical axiom count

These special kind of axioms are universally valid

Class count

Classes in ontologies are concepts. These classes can contain other classes or individuals. With this metric we count the classes to create a view on the quantity of classes.

Total class count

Object property count

Data property count
