Net-Filter The collection of all specializations of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rHIBS0h_TEdaAAABQ2rksLw" class="cyc_term">FirstOrderCollection</a>, that is, of all collections of (first-order) collections, and an instance of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rHUFI8h_TEdaAAABQ2rksLw" class="cyc_term">ThirdOrderCollection</a>. Instances of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rHQdVmB_TEdaAAABQ2rksLw" class="cyc_term">SecondOrderCollection</a> are collections of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rHIBS0h_TEdaAAABQ2rksLw" class="cyc_term">FirstOrderCollection</a>s.

(EquipmentTypeForStructuredActivityFn Tennis-TheGame) tennis equipment type of temporally stuff-like thing A specialization of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVir35wpEbGdrcN5Y29ycA" class="cyc_term">StuffType</a> (q.v.) whose instances are all and only those collections that are temporally stuff-like. A collection <code>COL</code> is temporally stuff-like just in case every purely temporal part (see <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvWn4OZwpEbGdrcN5Y29ycA" class="cyc_term">timeSlices</a>) of an instance of <code>COL</code> is itself an instance of <code>COL</code>, unless it is a temporal part of a temporal granule of <code>COL</code> (see <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjaJJwpEbGdrcN5Y29ycA" class="cyc_term">granuleOfTemporalStuff</a>). More precisely, for a collection <code>COL</code> to be an instance of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVitN5wpEbGdrcN5Y29ycA" class="cyc_term">TemporalStuffType</a> it is both a necessary and sufficient condition that for any <code>OBJ1</code> and <code>OBJ2</code> (with <code>OBJ2</code> at or above <code>COL</code>'s temporal granularity level), if <code>(<a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViBBJwpEbGdrcN5Y29ycA" class="cyc_term">isa</a> OBJ1 COL)</code> and <code>(<a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvWn4OZwpEbGdrcN5Y29ycA" class="cyc_term">timeSlices</a> OBJ1 OBJ2)</code>, then <code>(<a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViBBJwpEbGdrcN5Y29ycA" class="cyc_term">isa</a> OBJ2 COL)</code>. Consider <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVi0gpwpEbGdrcN5Y29ycA" class="cyc_term">WalkingOnTwoLegs</a>. Take an arbitrary instance <code>WALK</code> of this collection (say Miss America 2000's victory walk down the runway and back); and then take an arbitrary time-slice <code>SUBWALK</code> of <code>WALK</code> that subsumes at least one instance of (the <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjaJJwpEbGdrcN5Y29ycA" class="cyc_term">granuleOfTemporalStuff</a> for <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVi0gpwpEbGdrcN5Y29ycA" class="cyc_term">WalkingOnTwoLegs</a>) <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViYBpwpEbGdrcN5Y29ycA" class="cyc_term">TakingAStep</a> (say her trip back from the end of the runway). <code>SUBWALK</code> is itself an instance of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVi0gpwpEbGdrcN5Y29ycA" class="cyc_term">WalkingOnTwoLegs</a>. So <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVi0gpwpEbGdrcN5Y29ycA" class="cyc_term">WalkingOnTwoLegs</a> is an instance of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVitN5wpEbGdrcN5Y29ycA" class="cyc_term">TemporalStuffType</a>. See <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViq35wpEbGdrcN5Y29ycA" class="cyc_term">TemporalObjectType</a> for the disjoint notion of being temporally object-like.
