<h1><a name="ntView" id="ntView"></a>i2b2 Navigate Terms View</h1>
<p>The Navigate Terms view is designed to display the i2b2 vocabulary concepts that are maintained in the <b>Ontology Management Cell</b> of the <b>i2b2 Hive</b>. These concepts are used in many of the i2b2 views and plug-ins, such as the <i>Query Tool view</i>.
</p>
<p></p>
<h2><a name="ntIntro" id="ntIntro"></a>Introduction</h2>
<p>This section describes the layout and contents of this view.</p>

<h3><a name="ntLayout" id="ntLayout"></a>Layout of the Navigate Terms View</h3>
<p>The <b>Navigate Terms view</b> displays the terms listed in the metadata table(s). These terms are grouped (categorized) with other similar items. These groupings are displayed in a hierarchal tree that can be expanded to view all the concepts and modifiers in the associated category.
