<h2 id="semantic-web-implementation">Semantic Web implementation</h2> <p>The <a href="/facts/Resource_Description_Framework/WMufyukm">RDF</a> typed links are fundamental in <a href="/facts/Linked_data/XKhE5aTQ">LOD datasets</a> for identifying the relationship (predicate) type of <a href="/facts/RDF_triple/xL55zjps">RDF triples</a>, contributing to the automatic processability of machine-readable statements of the <a href="/facts/Giant_Global_Graph/jnuUB5WN">Giant Global Graph</a> on the <a href="/facts/Semantic_Web/NFHo9dB7">Semantic Web</a>. The typed links in RDF are expressed as the value of the rdf:type property, defining the relationship type using well-established <a href="/facts/Controlled_vocabulary/JcYKWx3H">controlled vocabulary</a> terms or definitions from LOD datasets such as </p> <rdf:type rdf:resource="http://schema.org/Person" /> <h2 id="external-links">External links</h2> <ul><li><a href="http://www.w3.org/TR/html401/types.html#type-links">rel values defined in HTML 4</a></li> <li><a href="https://wiki.whatwg.org/wiki/RelExtensions">rel values to be defined in HTML5</a></li> <li><a href="http://microformats.org/wiki/existing-rel-values">rel values which are defined in some specification</a></li> <li><a href="https://blog.whatwg.org/the-road-to-html-5-link-relations">WHATWG blog entry on link relations</a></li></ul> <h2 id="references">References</h2> <ol> <li id="fn:1"><p>Dubost, Karl (October 2005).
