<div class="sectionbody">
<div class="paragraph">
<p>This document specifies the behaviour of an API that supports the ability to
search collections of descriptive information, called records, about resources
such as data collections, services, processes, styles, code lists and other
related resources. Records represent resource characteristics that can be
queried and presented for evaluation and further processing by both humans
and software.</p>
</div>
<div class="paragraph">
<p>This specification defines a list of core queryables and a set of core query
parameter organized into X conformance classes.</p>

<h2 id="_conformance"><a class="anchor" href="#_conformance"></a>2. Conformance</h2>
<div class="sectionbody">
<div class="paragraph">
<p>Conformance with this standard shall be checked using the tests specified in Annex A (normative) of this document. The framework, concepts, and methodology for testing, and the criteria to claim conformance, are specified in the OGC Compliance Testing Policies and Procedures and the OGC Compliance Testing web site.</p>
</div>
<div class="paragraph">
<p>The one Standardization Target for this standard is Web APIs.</p>
</div>
<div class="paragraph">
<p>OGC API - Common provides a common foundation for OGC API standards. Therefore, this standard should be viewed as an extension to API - Common. Conformance to this standard requires demonstrated conformance to the applicable Conformance Classes of API - Common.</p>
</div>
<div class="paragraph">
<p>This standard identifies eleven (11) Conformance Classes. The Conformance Classes implemented by an API are advertised through the <code>/conformance</code> path on the landing page. Each Conformance Class has an associated Requirements Class. The Requirements Classes define the functional requirements which will be tested through the associated Conformance Class.</p>
</div>
<div class="paragraph">
<p>The Requirements Classes for OGC API - Records are:</p>
</div>
<div class="ulist">
<ul>
<li>
<p><strong>Core</strong></p>
</li>
<li>
<p><strong>Collections</strong></p>
</li>
<li>
<p><strong>OpenSearch</strong></p>
</li>
<li>
<p><strong>JSON-Record</strong></p>
</li>
<li>
<p><strong>ATOM-Record</strong></p>
</li>
<li>
<p><strong>HTML-Record</strong></p>
</li>
</ul>
</div>
<div class="paragraph">
<p>The <em>Core</em> Requirements Class is the minimal useful service interface for the OGC Records API. The requirements specified in this Requirements Class are mandatory for all implementations of API - Records. The core defines a set of mandatory properties (core queryables) that every record must contain, a set of core query parameters that support bounding box spatial queries, temporal queries, full text searching, parameters for sorting responses.</p>
</div>
<div class="paragraph">
<p>The <em>OpenSearch</em> Requirements Class defines the requirements to support query by OpenSearch clients.</p>
</div>
<div class="paragraph">
<p>The <em>Collections</em> Requirements Class defines requirements for making the
<code>/collections</code> endpoint of any OGC Web API searchable.</p>
</div>
<div class="paragraph">
<p>The <em>JSON</em> Requirements Class defines the requirements for a GeoJSON (see RFC 7946) representation of a standard catalogue record.</p>
</div>
<div class="paragraph">
<p>The <em>ATOM</em> Requirements Class defines the requirements for an ATOM representation of a standard catalogue record.</p>
</div>
<div class="paragraph">
<p>The <em>HTML</em> Requirements Class defines the requirements for an HTML representation of a standard catalogue record.</p>
