Triadic Relations and Meaning
Consider the context of a triadic relation, where each node in a triple (instance of this relation) plays a specific role, according it's place in the triple.
Let's use for this example, the relationship between three persons, one Son, a Father and a Mother. Note tha this three types of instance are played by instances of type Person, according to the rol / place in the relation triple.
Son = Mother::son(Father)
Mother = Father::mother(Son)
Father = Son::father(Mother)
According this, corresponds that a specific Son refers only one Mother and Father, that a Mother, according to one Son of her, refers only one Father. The same way, a Son and a Father refers only one Mother.
Another example:
Considering the relationship between an Author, a Title and a Piece.
1. A Title of an Author refers 1 Piece
2. An Author and a Piece refers 1 Title
3. A Piece and a Title refers 1 Author
Piece = Author::piece(Title)
Títle = Piece::title(Author)
Author = Title::author(Piece)
For certain Subject or 'real' thing there is a Topic (Name) representing it (like a handle). This Subject represents a Type instance representing Topic 't', which, in turns, represents another Subject.
Topic -> reifies -> Subject
Subject -> reifies -> Type
Type -> reifies -> Topic
Name (type.name(Value))
Type (value.type(Name))
Value(name.value(Type))
