just enough semantics?
There are several purposes for applying classification to data elements. Classification assists users to find a single data element from among many data elements, facilitates data administration analysis of data elements and, through inheritance, conveys semantic content that is often only incompletely specified by other attributes, such as names and definitions.
The classification schemes accommodated in this part have utility for
those that are trained
those that are included in this classification
those that tremble as if they were mad
those drawn with a very fine camel’s hair brush
those that have just broken a flower vase
those that resemble flies from a distanceBorgean Classification of Pigs

The property rdfs:subClassOf is an instance of rdf:Property that is used to state that all the instances of one class are instances of another.
A triple of the form:
C1 rdfs:subClassOf C2
states that C1 is an instance of rdfs:Class, C2 is an instance of rdfs:Class and C1 is a subclass of C2. The rdfs:subClassOf property is transitive.
The rdfs:domain of rdfs:subClassOf is rdfs:Class. The rdfs:range of rdfs:subClassOf is rdfs:Class
