Each instance of &lt;a href=&quot;http://sw.opencyc.org/2009/04/07/concept/en/CollectionWithAnEventLikeOrder&quot; class=&quot;cyc_term&quot;&gt;CollectionWithAnEventLikeOrder&lt;/a&gt; is a collection whose instances are conventionally regarded as being ordered by some relation &lt;code&gt;&lt;b&gt;RELN&lt;/b&gt;&lt;/code&gt;, where &lt;code&gt;&lt;b&gt;RELN&lt;/b&gt;&lt;/code&gt; orders the members of &lt;code&gt;&lt;b&gt;COL&lt;/b&gt;&lt;/code&gt; in the manner in which events are ordered in linear time.
&lt;p/&gt;
More precisely, a collection is an instance of &lt;a href=&quot;http://sw.opencyc.org/2009/04/07/concept/en/CollectionWithAnEventLikeOrder&quot; class=&quot;cyc_term&quot;&gt;CollectionWithAnEventLikeOrder&lt;/a&gt; just in case its instances are conventially regarded as being ordered by a relation &lt;code&gt;&lt;b&gt;RELN&lt;/b&gt;&lt;/code&gt; such that the &lt;a href=&quot;http://sw.opencyc.org/2009/04/07/concept/en/MathematicalOrdering&quot; class=&quot;cyc_term&quot;&gt;MathematicalOrdering&lt;/a&gt; whose &lt;a href=&quot;http://sw.opencyc.org/2009/04/07/concept/en/baseSet&quot; class=&quot;cyc_term&quot;&gt;baseSet&lt;/a&gt; is &lt;code&gt;&lt;b&gt;COL&lt;/b&gt;&lt;/code&gt;, and whose &lt;a href=&quot;http://sw.opencyc.org/2009/04/07/concept/en/orderingRelation&quot; class=&quot;cyc_term&quot;&gt;orderingRelation&lt;/a&gt; is &lt;code&gt;&lt;b&gt;RELN&lt;/b&gt;&lt;/code&gt;, is an instance of &lt;a href=&quot;http://sw.opencyc.org/2009/04/07/concept/en/EventLikeOrdering&quot; class=&quot;cyc_term&quot;&gt;EventLikeOrdering&lt;/a&gt; (q.v.).
&lt;p/&gt;
For example, the instances of &lt;a href=&quot;http://sw.opencyc.org/2009/04/07/concept/en/Distance&quot; class=&quot;cyc_term&quot;&gt;Distance&lt;/a&gt; are conventionally regarded as being ordered by the relation &lt;i&gt;&lt;b&gt;greater than&lt;/b&gt;&lt;/i&gt;, and this ordering is event-like.  So &lt;a href=&quot;http://sw.opencyc.org/2009/04/07/concept/en/Distance&quot; class=&quot;cyc_term&quot;&gt;Distance&lt;/a&gt; is a collection with an event-like order.</rdfs:comment>

Positive examples of ANECTs include &lt;a href=&quot;http://sw.opencyc.org/2009/04/07/concept/en/Collection&quot; class=&quot;cyc_term&quot;&gt;Collection&lt;/a&gt;, &lt;a href=&quot;http://sw.opencyc.org/2009/04/07/concept/en/Integer&quot; class=&quot;cyc_term&quot;&gt;Integer&lt;/a&gt;, and &lt;a href=&quot;http://sw.opencyc.org/2009/04/07/concept/en/Relation&quot; class=&quot;cyc_term&quot;&gt;Relation&lt;/a&gt; (each of which is a collection of atemporals and is such that, necessarily, all of its instances are in it essentially).  Negative examples include &lt;a href=&quot;http://sw.opencyc.org/2009/04/07/concept/en/SpatialThing&quot; class=&quot;cyc_term&quot;&gt;SpatialThing&lt;/a&gt; (though arguably it is necessary that all of its instances are essentially instances of it, it is not disjoint with &lt;a href=&quot;http://sw.opencyc.org/2009/04/07/concept/en/TemporalThing&quot; class=&quot;cyc_term&quot;&gt;TemporalThing&lt;/a&gt;) and &lt;a href=&quot;http://sw.opencyc.org/2009/04/07/concept/en/UniqueAnatomicalPartType&quot; class=&quot;cyc_term&quot;&gt;UniqueAnatomicalPartType&lt;/a&gt; (which, though disjoint with &lt;a href=&quot;http://sw.opencyc.org/2009/04/07/concept/en/TemporalThing&quot; class=&quot;cyc_term&quot;&gt;TemporalThing&lt;/a&gt;, has instances, such as &lt;a href=&quot;http://sw.opencyc.org/2009/04/07/concept/en/Heart&quot; class=&quot;cyc_term&quot;&gt;Heart&lt;/a&gt;, that could exist even if they weren&apos;t instances of it; e.g. it might have been the case that every creature with a heart had at least two hearts).  There are no known examples of Cyc-reified collections satisfying conditions (1) and (2) but not (3), but one can be contrived.  Suppose that all of today&apos;s winning lottery numbers were primes.  Now consider the collection:
&lt;p/&gt;
 (&lt;a href=&quot;http://sw.opencyc.org/2009/04/07/concept/en/CollectionUnionFn&quot; class=&quot;cyc_term&quot;&gt;CollectionUnionFn&lt;/a&gt; 
   (&lt;a href=&quot;http://sw.opencyc.org/2009/04/07/concept/en/TheSet&quot; class=&quot;cyc_term&quot;&gt;TheSet&lt;/a&gt; &lt;a href=&quot;http://sw.opencyc.org/2009/04/07/concept/en/PrimeNumber&quot; class=&quot;cyc_term&quot;&gt;PrimeNumber&lt;/a&gt; &lt;i&gt;TodaysWinningLotteryNumbers&lt;/i&gt;))
&lt;p/&gt;
This collection is clearly disjoint with &lt;a href=&quot;http://sw.opencyc.org/2009/04/07/concept/en/TemporalThing&quot; class=&quot;cyc_term&quot;&gt;TemporalThing&lt;/a&gt; and, by hypothesis, all of its instances are in it essentially (as each prime number is essentially a prime number).  But this last fact is not &lt;i&gt;necessarily&lt;/i&gt; true of this collection: the collection might have had instances that belonged to it only contingently (i.e. not essentially), as it might have been the case that one of today&apos;s winning lottery numbers was non-prime, and no number is such that it is essentially one of today&apos;s winning lottery numbers.
&lt;p/&gt;
When asserting that something is an instance or specialization of a given instance of ANECT, it is appropriate to do so in the &lt;a href=&quot;http://sw.opencyc.org/2009/04/07/concept/en/UniversalVocabularyMt&quot; class=&quot;cyc_term&quot;&gt;UniversalVocabularyMt&lt;/a&gt; (q.v.).  Indeed, ANECT was specially defined to facilitate the movement of appropriate assertions to that microtheory.

Division in time or space does not destroy the stufflike quality of the object (down to a certain granularity).

For example, every piece of wood is temporally stufflike: if W-168 is a piece of wood during 1996, then it&apos;s also a piece of wood for the one-minute time-slice 9:05am 7/7/96.  It&apos;s also spatially stufflike: if we take that piece of wood W-168 and cut it in half, we have two things which are both pieces of wood.  Since every piece of wood is both temporally and spatially stufflike, &lt;a href=&quot;http://sw.opencyc.org/2009/04/07/concept/en/Wood&quot; class=&quot;cyc_term&quot;&gt;Wood&lt;/a&gt; is an instance of &lt;a href=&quot;http://sw.opencyc.org/2009/04/07/concept/en/ExistingStuffType&quot; class=&quot;cyc_term&quot;&gt;ExistingStuffType&lt;/a&gt;.  Other instances of &lt;a href=&quot;http://sw.opencyc.org/2009/04/07/concept/en/ExistingStuffType&quot; class=&quot;cyc_term&quot;&gt;ExistingStuffType&lt;/a&gt; include the collections &lt;font color=&quot;#ff0000&quot;&gt;#$AppleJuice&lt;/font&gt;, &lt;a href=&quot;http://sw.opencyc.org/2009/04/07/concept/en/IceCream&quot; class=&quot;cyc_term&quot;&gt;IceCream&lt;/a&gt;, &lt;a href=&quot;http://sw.opencyc.org/2009/04/07/concept/en/Diamond&quot; class=&quot;cyc_term&quot;&gt;Diamond&lt;/a&gt;, &lt;a href=&quot;http://sw.opencyc.org/2009/04/07/concept/en/WaxedPaper&quot; class=&quot;cyc_term&quot;&gt;WaxedPaper&lt;/a&gt;, and &lt;a href=&quot;http://sw.opencyc.org/2009/04/07/concept/en/StriatedMuscle&quot; class=&quot;cyc_term&quot;&gt;StriatedMuscle&lt;/a&gt;.
