Semantic Web Language Feature Usage

Below are some general information about this ontology. The analytical results are generated based on Semantic Web Ontology Analysis Techniques.

RDF

{{#vardefine:ns| }}{{#vardefine:p|number of triples }}{{#vardefine:v|156 }}

OWL

{{#vardefine:ns| }}{{#vardefine:p|OWL Species }}{{#vardefine:v|Full }} {{#vardefine:ns| }}{{#vardefine:p|DL Expressivity }}{{#vardefine:v|ALCHIF(Dk) }}

AL - Attribute Logic: Conjunction, Universal Value Restriction, Limited Existential Quantification 
H - Role hierarchy
I - Inverse Role 
F - Functionality
(D) - Datatypes

Usage of OWL Constructs

OWL Validation (execute)

• Inverse
• Functional
