      A natural-language representation for a concept that is both human 
      readable and readable by the Cyc inference engine. These terms are not 
      guaranteed to refer to the same concept across time but are guaranteed to
      be consistent within a particular OWL export. Use 'cycAnnot:externalID'

      inference engines.

    <rdfs:label xml:lang="en">type of object whose instances do not physically overlap</rdfs:label>
    <rdfs:comment xml:lang="en">A collection of collections and a specialization of &lt;a href=&quot;http://sw.opencyc.org/concept/Mx4rvVirnZwpEbGdrcN5Y29ycA&quot; class=&quot;cyc_term&quot;&gt;ObjectType&lt;/a&gt; (q.v.). Each instance of &lt;a href=&quot;http://sw.opencyc.org/concept/Mx4rpPHhAOB1EdqAAAACs6hRXg&quot; class=&quot;cyc_term&quot;&gt;SpatiallyDisjointObjectType&lt;/a&gt; is a collection C of spatial things (see &lt;a href=&quot;http://sw.opencyc.org/concept/Mx4rvVjpUZwpEbGdrcN5Y29ycA&quot; class=&quot;cyc_term&quot;&gt;SpatialThing&lt;/a&gt;), where each of the spatial things in C is spatially disjoint with the other spatial things in C.
&lt;p/&gt;
For example, the collection &lt;a href=&quot;http://sw.opencyc.org/concept/Mx4rvVjaoJwpEbGdrcN5Y29ycA&quot; class=&quot;cyc_term&quot;&gt;Dog&lt;/a&gt; is an instance of &lt;a href=&quot;http://sw.opencyc.org/concept/Mx4rpPHhAOB1EdqAAAACs6hRXg&quot; class=&quot;cyc_term&quot;&gt;SpatiallyDisjointObjectType&lt;/a&gt;, since dogs do not spatially overlap.  Even pregnant dogs do not spatially overlap the pups they bear; rather, pregnant dogs contain their unborn pups.  Other instances of &lt;a href=&quot;http://sw.opencyc.org/concept/Mx4rpPHhAOB1EdqAAAACs6hRXg&quot; class=&quot;cyc_term&quot;&gt;SpatiallyDisjointObjectType&lt;/a&gt; include &lt;a href=&quot;http://sw.opencyc.org/concept/Mx4rwVGrQ5wpEbGdrcN5Y29ycA&quot; class=&quot;cyc_term&quot;&gt;LatitudeLine&lt;/a&gt;, &lt;a href=&quot;http://sw.opencyc.org/concept/Mx4rvW4n1pwpEbGdrcN5Y29ycA&quot; class=&quot;cyc_term&quot;&gt;CompactDisc_Audio&lt;/a&gt;, and &lt;a href=&quot;http://sw.opencyc.org/concept/Mx4rwR7UWZwpEbGdrcN5Y29ycA&quot; class=&quot;cyc_term&quot;&gt;PlanetaryBody&lt;/a&gt;.
