RDF Schema

RDF Schema is an extension of the basic RDF vocabulary that provides a data-modelling vocabulary for RDF data.
The core vocabulary of RDF Schema is in the namespace http://www.w3.org/2000/01/rdf-schema#.
This namespace is typically associated with the prefix rdfs:.
Concerning the two prefixes rdf: and rdfs:, the RDF 1.1 Primer says:
The fact that the constructs have two different prefixes (rdf: and rdfs:) is a somewhat annoying historical artefact, which is preserved for backward compatibility.
rdfs:Resource The root class in RDF Schema. All other classes are subclasses of this class.
rdfs:Class The group of resources that are classes. So, for example, rdfs:Resource or rdfs:Class are instances of rdfs:Class.
rdfs:subClassOf States that a class is a subclass of another
rdfs:Literal The class of literal values.
rdfs:Datatype The class of datatypes. Each instance of rdfs:Datatype is a subclass of rdfs:Literal
rdf:langString The class of language tagged string values. rdf:langString is an instance of rdfs:Datatype and a subclass of rdfs:Literal
rdf:HTML The class of HTML literal values.
rdf:XML The class of XML literal values.
rdf:Property The class of RDF properties.
rdfs:subPropertyOf Used to state that one property is a subproperty of another property.
rdfs:range prop rdfs:range cls states that prop is an instance of rdf:Property, cls an instance of rdfs:Class and that prop denotes object-resources that are instances of cls
rdfs:domain prop rdfs:domain cls states that prop is an instance of rdf:Property, cls an instance of rdfs:Class and that prop denotes subject -resources that are instances of cls.
rdf:type inst rdf:type cls states that cls is an instance of rdfs:Class and inst is an instance of cls. rdf:type is an instance of rdf:Property. rdf:type can be abbreviated with a.
rdfs:subClassOf
rdfs:subPropertyOf
rdfs:label rsrc rdfs:label lbl states that lbl is a human-readable label of the resource rsrc. The rdfs:domain of rdfs:label is rdfs:Resource. The rdfs:range of rdfs:label is rdfs:Literal.
rdfs:comment Similar to rdfs:label, but commant instead of label (?)
rdfs:Container The super-class of the RDF container classes rdf:Bag, rdf:Seq and rdf:Alt.
rdfs:Bag Unordered set
rdfs:Seq Ordered set
rdfs:Alt
rdfs:ContainerMembershipProperty The instances of this class are the properties rdf:_1, :rdf:_2, rdf:_3
rdfs:member
rdf:List
rdf:first
rdf:rest
rdf:nil
rdf:Statement The class of RDF statements
rdf:subject rdf:subject is an instance of rdf:Property that states a statement's subject.
rdf:predicate
rdf:object
rdfs:seeAlso
rdfs:isDefinedBy
rdf:value
