{title:'RDF Details'}

<p>
	Juneau supports serializing and parsing arbitrary POJOs to and from the following RDF formats:
</p>
<ul>
	<li>RDF/XML
	<li>Abbreviated RDF/XML
	<li>N-Triple
	<li>Turtle
	<li>N3
</ul>

<p>
	The serializers and parsers work identically to those in <c>juneau-marshall</c>, but are
	packaged separately so that you don't need to pull in the Jena dependency unless you need it.
</p>
