## Overview
|
|
|
|
The **Resource Description Framework** (RDF) is the foundational representation language of the Semantic Web. The basic building block of RDF is the **triple** containing a **subject**, **predicate**, and **object**. Global identifiers of resources are represented as [[uri|URIs]] (or, more generally, IRIs). These URIs can be expressed more compactly as [[uri#CURIEs|CURIEs]].

## Standard Namespaces
|
|
|
|
W3C have defined a number of standard namespaces for use with Web technologies:
|
|
|
|
* `xsd`
|
|
* Refers to the XML schema definition.
|
|
* `xmlns`
|
|
* Refers to XML namespaces.
|
|
* `rdf`
|
|
* Refers to identifiers used in RDF.
