Figure 3

The core classes of the taxonomic meta-ontology. The classes are illustrated with ellipses (colours are to improve the readability of the figure). The arrows indicate relations (properties) between the classes. The subclass relations are indicated with lighter-coloured arrows and a few examples of the subclasses. To demonstrate how the TaxMeOn model is applied, an example taxon depicted using dotted lines is illustrated. The example taxon is an instance of the class TaxonInChecklist and of a specific taxonomic rank. The properties associated with the example taxon are marked with dotted-line arrows. The properties with literal values are not shown in the figure.
