È costituito da due componenti: </p> <ul><li><b>RDF Model and Syntax</b>: espone la struttura del modello RDF, e descrive una possibile sintassi.</li> <li><b>RDF Schema</b>: espone la sintassi per definire schemi e vocabolari per i metadati.</li></ul> <p>L'RDF Data Model si basa su tre principi chiave: </p> <ol><li>Qualunque cosa può essere identificata da un <a href="/wiki/Uniform_Resource_Identifier" title="Uniform Resource Identifier">Uniform Resource Identifier</a> (URI).</li> <li><i>The least power</i>: utilizzare il linguaggio meno espressivo per definire qualunque cosa.</li> <li>Qualunque cosa può dire qualunque cosa su qualunque cosa.</li></ol> <meta property="mw:PageProp/toc" /> <div class="mw-heading mw-heading2"><h2 id="Principi_e_modello_dei_dati">Principi e modello dei dati</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Resource_Description_Framework&veaction=edit&section=1" title="Modifica la sezione Principi e modello dei dati" class="mw-editsection-visualeditor"><span>modifica</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Resource_Description_Framework&action=edit&section=1" title="Edit section's source code: Principi e modello dei dati"><span>modifica wikitesto</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Qualunque cosa descritta da RDF è detta risorsa. Principalmente una risorsa è reperibile sul <a href="/wiki/Web" class="mw-redirect" title="Web">web</a>, ma RDF può descrivere anche risorse che non si trovano direttamente sul <a href="/wiki/Web" class="mw-redirect" title="Web">web</a>. Ogni risorsa è identificata da un URI, <a href="/wiki/Uniform_Resource_Identifier" title="Uniform Resource Identifier">Uniform Resource Identifier</a>. </p><p>Il modello di dati RDF è formato da risorse, proprietà e valori. Le proprietà sono delle relazioni che legano tra loro risorse e valori, e sono anch'esse identificate da URI. Un valore, invece, è un tipo di dato primitivo, che può essere una stringa contenente l'URI di una risorsa. </p><p>L'unità base per rappresentare un'informazione in RDF è lo statement. Uno statement è una tripla del tipo <i>Soggetto</i> – <i>Predicato</i> – <i>Oggetto</i>, dove il soggetto è una risorsa, il predicato è una proprietà e l'oggetto è un valore (e quindi anche un URI che punta ad un'altra risorsa). </p><p>Il data model RDF permette di definire un modello semplice per descrivere le relazioni tra le risorse, in termini di proprietà identificate da un nome e relativi valori. Tuttavia, RDF data model non fornisce nessun meccanismo per dichiarare queste proprietà, né per definire le relazioni tra queste proprietà ed altre risorse. Tale compito è definito da RDF Schema. </p> <div class="mw-heading mw-heading2"><h2 id="RDF_Container">RDF Container</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Resource_Description_Framework&veaction=edit&section=2" title="Modifica la sezione RDF Container" class="mw-editsection-visualeditor"><span>modifica</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Resource_Description_Framework&action=edit&section=2" title="Edit section's source code: RDF Container"><span>modifica wikitesto</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>RDF quando deve far riferimento a più di una risorsa, per esempio per descrivere il fatto che la risorsa è associata a più proprietà, definisce dei contenitori (container), ossia liste di risorse.

Per esempio i componenti di un convegno.</li> <li><b>Sequence</b>, differisce da Bag per il fatto che l'ordine delle risorse è significativo. Per esempio si vuole mantenere l'ordine alfabetico di un insieme di nomi, gli autori di un sito.</li> <li><b>Alternative</b>, è una lista di risorse che definiscono un'alternativa per il valore singolo di una proprietà.
