              &lt;code&gt;http://hl7.org/fhir/linkage-type&lt;/code&gt; defines the following codes:

                &lt;td&gt;Source of Truth&lt;/td&gt;
                &lt;td&gt;The resource represents the &amp;quot;source of truth&amp;quot; (from the perspective of this Linkage resource) for the underlying event/condition/etc.&lt;/td&gt;

                &lt;td&gt;Historical/Obsolete Record&lt;/td&gt;
