An Interpretation is:

0. A set LV and a mapping XL from <qLiteral> to LV

1. A nonempty set IR of resources, called the domain or universe of I.

2. A non-empty subset IP of IR called Properties

3. A mapping IEXT from IP into the powerset of IRx(IR union LV)

4. A mapping IS: vocab(I) -> IR

Basic RDF model theory

IR could overlap LV

i.e. a subset of pairs <x,y> with x in IR and y in either IR or LV.

This is basically a table of the values of this property for each object. If some object isn’t mentioned then it doesn’t have a value for this property

IS assigns semantic values to a subset of the total RDF vocabulary.
