Making vocabularies

• A set of shared concepts
• Properties are things to use as predicates (verbs)

  Classes can be the type of an object

  rdf:type is just a property, abbrevaiated to "a" in N3

• You can invent them and describe Properties and Classes.

Equivalent:

:Person rdf:type  rdfs:Class

:Person a rdfs:Class.

which we could use with data;

:Pat a :Person.
