All of the RDF & OWL documents are so preoccupied
with properties that they ignore the things that
have those properties.
There are at least two classes that are absolutely
essential in order to avoid the current chaos that is
the result of ignoring those things that have properties.
Entity
Group
Entity is the class of primary things which exist, including
those which we perceive directly, e.g., people, trees, cars.
These physical entities have properties which can used to
classify them as members of various Groups. Groups are
abstract entities which are created by people, e.g., sets,
lists, hierarchies, classes.
Here is a useful high-level class hierarchy which includes
Entity and Group.
Thing
Entity
Animal
Person
Plant
Object
Group
Set
List
Hierarchy
Class
Company
Property
Part
Attribute
Relation
Action
Interaction
Proposition
Context
Sentence
Statement
The above is a good, general-purpose hierarchy, but
it may not be the best hierarchy for any particular
situation. It is to be expected that users will
modify the class hierarchy to suit their own purposes.
