&lt;p/&gt;
Consider the collection &lt;a href=&quot;http://sw.opencyc.org/2008/06/10/concept/Mx4rwJaXepwpEbGdrcN5Y29ycA&quot; class=&quot;cyc_term&quot;&gt;BookCopy&lt;/a&gt;. &lt;a href=&quot;http://sw.opencyc.org/2008/06/10/concept/Mx4rwJaXepwpEbGdrcN5Y29ycA&quot; class=&quot;cyc_term&quot;&gt;BookCopy&lt;/a&gt; is a specialization of &lt;a href=&quot;http://sw.opencyc.org/2008/06/10/concept/Mx4rvVj27ZwpEbGdrcN5Y29ycA&quot; class=&quot;cyc_term&quot;&gt;PartiallyTangible&lt;/a&gt;. Further, &lt;a href=&quot;http://sw.opencyc.org/2008/06/10/concept/Mx4rwJaXepwpEbGdrcN5Y29ycA&quot; class=&quot;cyc_term&quot;&gt;BookCopy&lt;/a&gt; is temporally stuff-like: any one of the &lt;a href=&quot;http://sw.opencyc.org/2008/06/10/concept/Mx4rvWn4OZwpEbGdrcN5Y29ycA&quot; class=&quot;cyc_term&quot;&gt;timeSlices&lt;/a&gt; of a given copy &lt;code&gt;&lt;b&gt;COPY&lt;/b&gt;&lt;/code&gt; of (say) &amp;quot;Moby Dick&amp;quot; is still a copy of &amp;quot;Moby Dick&amp;quot;. (Most collections of tangible objects are temporally stuff-like in this way.)   But &lt;a href=&quot;http://sw.opencyc.org/2008/06/10/concept/Mx4rwJaXepwpEbGdrcN5Y29ycA&quot; class=&quot;cyc_term&quot;&gt;BookCopy&lt;/a&gt; is spatially &lt;i&gt;object-like&lt;/i&gt;: if we take a scalpel and slice &lt;code&gt;&lt;b&gt;COPY&lt;/b&gt;&lt;/code&gt; into ten pieces, each piece is not a copy of &amp;quot;Moby Dick&amp;quot;.  So &lt;a href=&quot;http://sw.opencyc.org/2008/06/10/concept/Mx4rwJaXepwpEbGdrcN5Y29ycA&quot; class=&quot;cyc_term&quot;&gt;BookCopy&lt;/a&gt; is an instance of &lt;a href=&quot;http://sw.opencyc.org/2008/06/10/concept/Mx4rvWXYgJwpEbGdrcN5Y29ycA&quot; class=&quot;cyc_term&quot;&gt;ExistingObjectType&lt;/a&gt;.
