Each class defined must be of RDFS Class. For this there is nName-pPrefix that is used for the RDF namespace. With RDF Class one can define Abstract Objects that are applied via rdf:type to create Instances of this Class. rdf:Property is the base Class of all Properties, any property must be of this class. The base class of all Literals is rdfs:Literal. In the end all things are a subclass of some topclass that is ontop of all Class Hierarchy, which is the rdfs:Resource. So everything that is modeled is some kind of class of a resource. Everything in RDF is a resource. ¶
There are also general classes for Datatype, additional there is a general class for Literals that stem from XML Schema Definition as there are some datatypes that can come from XML Schema. There is also a class for Container which are the aggregations of lists of RDF statements. For being a member of an container there is an RDF Membership Properties that define nothing else than membership to a given RDF Container. ¶

A property always relates one class with another, therefore one has to define which is the domain and which is the range class.
