RDF Schema (RDFS) extends RDF.


Defining datatypes in RDF are the part of RDF Schema. You can use RDFS to bind a property (attribute) to a datatype. Basically we use existing datatypes like the ones in XML Schema.

<rdf:Property rdf:ID="price">
 <rdfs:domain="Tool" />
 <rdfs:datatype="money" />

<!-- extend xsd with a money datatype -->
<xsd:complexType name="money">
    <xsd:extension base="xsd:decimal">
      <xsd:attribute name="currency" type="currencies"/>
