    <rdfs:comment xml:lang="en">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.) whose instances are all and only those collections that are temporally object-like. A collection &lt;code&gt;&lt;b&gt;COL&lt;/b&gt;&lt;/code&gt; is temporally object-like just in case it generally holds that any proper purely temporal parts (see &lt;a href=&quot;http://sw.opencyc.org/concept/Mx4rvWn4OZwpEbGdrcN5Y29ycA&quot; class=&quot;cyc_term&quot;&gt;timeSlices&lt;/a&gt;) of an instance of &lt;code&gt;&lt;b&gt;COL&lt;/b&gt;&lt;/code&gt; is not itself an instance of &lt;code&gt;&lt;b&gt;COL&lt;/b&gt;&lt;/code&gt;.  More precisely, a collection &lt;code&gt;&lt;b&gt;COL&lt;/b&gt;&lt;/code&gt; is an instance of &lt;a href=&quot;http://sw.opencyc.org/concept/Mx4rvViq35wpEbGdrcN5Y29ycA&quot; class=&quot;cyc_term&quot;&gt;TemporalObjectType&lt;/a&gt; just in case it satisfies the following: For any distinct &lt;code&gt;&lt;b&gt;OBJ1&lt;/b&gt;&lt;/code&gt; and &lt;code&gt;&lt;b&gt;OBJ2&lt;/b&gt;&lt;/code&gt;, if &lt;code&gt;(&lt;a href=&quot;http://sw.opencyc.org/concept/Mx4rvViBBJwpEbGdrcN5Y29ycA&quot; class=&quot;cyc_term&quot;&gt;isa&lt;/a&gt; &lt;b&gt;OBJ1&lt;/b&gt; &lt;b&gt;COL&lt;/b&gt;)&lt;/code&gt; and &lt;code&gt;(&lt;a href=&quot;http://sw.opencyc.org/concept/Mx4rvWn4OZwpEbGdrcN5Y29ycA&quot; class=&quot;cyc_term&quot;&gt;timeSlices&lt;/a&gt; &lt;b&gt;OBJ1&lt;/b&gt; &lt;b&gt;OBJ2&lt;/b&gt;)&lt;/code&gt;, then &lt;i&gt;not&lt;/i&gt; &lt;code&gt;(&lt;a href=&quot;http://sw.opencyc.org/concept/Mx4rvViBBJwpEbGdrcN5Y29ycA&quot; class=&quot;cyc_term&quot;&gt;isa&lt;/a&gt; &lt;b&gt;OBJ2&lt;/b&gt; &lt;b&gt;COL&lt;/b&gt;)&lt;/code&gt;.
&lt;p/&gt;
For example, none of the proper time-slices of a &lt;a href=&quot;http://sw.opencyc.org/concept/Mx4rvVjyV5wpEbGdrcN5Y29ycA&quot; class=&quot;cyc_term&quot;&gt;CalendarYear&lt;/a&gt; is itself a calendar year.  Likewise for &lt;a href=&quot;http://sw.opencyc.org/concept/Mx4rvViYBpwpEbGdrcN5Y29ycA&quot; class=&quot;cyc_term&quot;&gt;TakingAStep&lt;/a&gt;.  So &lt;a href=&quot;http://sw.opencyc.org/concept/Mx4rvVjyV5wpEbGdrcN5Y29ycA&quot; class=&quot;cyc_term&quot;&gt;CalendarYear&lt;/a&gt; and &lt;a href=&quot;http://sw.opencyc.org/concept/Mx4rvViYBpwpEbGdrcN5Y29ycA&quot; class=&quot;cyc_term&quot;&gt;TakingAStep&lt;/a&gt; are both instances of &lt;a href=&quot;http://sw.opencyc.org/concept/Mx4rvViq35wpEbGdrcN5Y29ycA&quot; class=&quot;cyc_term&quot;&gt;TemporalObjectType&lt;/a&gt;. Conversely, a proper time-slice of a given &lt;a href=&quot;http://sw.opencyc.org/concept/Mx4rvVisWZwpEbGdrcN5Y29ycA&quot; class=&quot;cyc_term&quot;&gt;Date&lt;/a&gt; might itself be a &lt;a href=&quot;http://sw.opencyc.org/concept/Mx4rvVisWZwpEbGdrcN5Y29ycA&quot; class=&quot;cyc_term&quot;&gt;Date&lt;/a&gt; (e.g. an hour has minutes and seconds as time-slices); so &lt;a href=&quot;http://sw.opencyc.org/concept/Mx4rvVisWZwpEbGdrcN5Y29ycA&quot; class=&quot;cyc_term&quot;&gt;Date&lt;/a&gt; is &lt;i&gt;not&lt;/i&gt; a temporal-object-type.
&lt;p/&gt;
See &lt;a href=&quot;http://sw.opencyc.org/concept/Mx4rvVitN5wpEbGdrcN5Y29ycA&quot; class=&quot;cyc_term&quot;&gt;TemporalStuffType&lt;/a&gt; for the disjoint notion of being temporally stuff-like.</rdfs:comment>
