This is a taxonomic dictionary, which means that the defined concepts are arranged in a strict subtype-supertype hierarchy, also called a taxonomy.
The dictionary defines kinds of relations that are usually not found in conventional dictionaries. A number of the kinds of relations are also defined in various ISO and non-ISO standards.
Kinds of relations are widely used in information modeling and database design and for making expressions in formal languages as well as in RDF or OWL based data exchange messages and triple stores. This dictionary is a basic section of a much larger electronic ontological dictionary that defines the Gellish family of formalized languages, especially Formal English. Formal languages are meant for storing, searching and finding information by expressing and exchanging queries and information in a computer interpretable and system independent way.
