In such systems, a change or reclassification is possible by a decision of an authority, or by a changed social agreement or custom, without changing the intrinsic natures of the actual objects in the category. <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvubaMZwpEbGdrcN5Y29ycA" class="cyc_term">ConventionalClassificationType</a>s include categories in biological taxonomy, standard classifications in data dictionaries and thesauri, cultural taboo classes, military doctrinal classes, and named calendar intervals.

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.

Every thing in the Cyc ontology -- every <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjaApwpEbGdrcN5Y29ycA" class="cyc_term">Individual</a> (of any kind), every <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvl2en5wpEbGdrcN5Y29ycA" class="cyc_term">Set_Mathematical</a>, and every <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViAzJwpEbGdrcN5Y29ycA" class="cyc_term">Collection</a> -- is an instance of (see <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViBBJwpEbGdrcN5Y29ycA" class="cyc_term">isa</a>) <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViA9JwpEbGdrcN5Y29ycA" class="cyc_term">Thing</a>. Similarly, every collection is a subcollection of (see <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViBDpwpEbGdrcN5Y29ycA" class="cyc_term">genls</a>) <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViA9JwpEbGdrcN5Y29ycA" class="cyc_term">Thing</a>. Trivially, <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViA9JwpEbGdrcN5Y29ycA" class="cyc_term">Thing</a> is both an instance of and a subcollection of itself, and is not a subcollection of any other collection. (Note that the above reference to "every thing in the Cyc ontology" is not meant to be limited to things actually reified in the Cyc system, but includes (e.g.) every instance -- reified or not, known or not -- of every collection recognized by Cyc.) Pretty String (<a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rwLSVCpwpEbGdrcN5Y29ycA" class="cyc_term">prettyString</a> TERM STRING) means that STRING is the English word or expression (sequence of words) commonly used to refer to TERM. The predicate <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rwLSVCpwpEbGdrcN5Y29ycA" class="cyc_term">prettyString</a> is used by the code which generates CycL to English paraphrases, but its applicability is not restricted to this use. prettyString minor terrain type Instances of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4r3DIuwO0OQdeFmbzex52KAQ" class="cyc_term">MilitaryMinorTerrainType</a> are types of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjOh5wpEbGdrcN5Y29ycA" class="cyc_term">LandTopographicalFeature</a>s that are explicitly defined in military documentation as 'minor terrain features.'
