'''Turtle''' (Terse RDF Triple Language) is a W3C Recommendation described a textual syntax for RDF called Turtle that allows an RDF graph to be completely written in a compact and natural text form, with abbreviations for common usage patterns and datatypes.

== Examples ==

Examples from the recommendation.

Describes the relationship between Green Goblin and Spiderman:

<pre>
@base <http://example.org/> .
@prefix rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#> .
@prefix rdfs: <http://www.w3.org/2000/01/rdf-schema#> .
@prefix foaf: <http://xmlns.com/foaf/0.1/> .
@prefix rel: <http://www.perceive.net/schemas/relationship/> .

<#green-goblin>
rel:enemyOf <#spiderman> ;
a foaf:Person ; # in the context of the Marvel universe
foaf:name "Green Goblin" .

<#spiderman>
rel:enemyOf <#green-goblin> ;
a foaf:Person ;
foaf:name "Spiderman", "Человек-паук"@ru .
</pre>

An example showing how numbers can be encoded:

<pre>
@prefix : <http://example.org/elements> .
<http://en.wikipedia.org/wiki/Helium>
:atomicNumber 2 ; # xsd:integer
:atomicMass 4.002602 ; # xsd:decimal
:specificGravity 1.663E-4 . # xsd:double
</pre>

An example of Turtle embedded in a HTML document:

<pre>
<script type="text/turtle">
@prefix dc: <http://purl.org/dc/terms/> .
@prefix frbr: <http://purl.org/vocab/frbr/core#> .

<http://books.example.com/works/45U8QJGZSQKDH8N> a frbr:Work ;

<http://books.example.com/products/9780596007683.BOOK> a frbr:Expression ;
