Every thing in the Cyc ontology -- every <a href="http://sw.opencyc.org/2008/06/10/concept/en/Individual" class="cyc_term">Individual</a> (of any kind), every <a href="http://sw.opencyc.org/2008/06/10/concept/en/Set_Mathematical" class="cyc_term">Set_Mathematical</a>, and every <a href="http://sw.opencyc.org/2008/06/10/concept/en/Collection" class="cyc_term">Collection</a> -- is an instance of (see <a href="http://sw.opencyc.org/2008/06/10/concept/en/isa" class="cyc_term">isa</a>) <a href="http://sw.opencyc.org/2008/06/10/concept/en/Thing" class="cyc_term">Thing</a>. Similarly, every collection is a subcollection of (see <a href="http://sw.opencyc.org/2008/06/10/concept/en/genls" class="cyc_term">genls</a>) <a href="http://sw.opencyc.org/2008/06/10/concept/en/Thing" class="cyc_term">Thing</a>.

(Note that the above reference to &quot;every thing in the Cyc ontology&quot; is <i>not</i> meant to be limited to things actually <i>reified</i> in the Cyc system, but includes (e.g.) every instance -- reified or not, known or not -- of every collection recognized by Cyc.)

This is the collection of all and only those collections <code><b>COL</b></code> such that any thing's being an instance of <code><b>COL</b></code> depends on the current state of the <a href="http://sw.opencyc.org/2008/06/10/concept/en/CycKB" class="cyc_term">CycKB</a>. Such a <code><b>COL</b></code> corresponds to a property defined (at least partly) in terms of the contents, features, or implementation of the Cyc Knowledge Base itself, as opposed to a property that &quot;exists out there&quot; in the KB-independent world. <p/> For example, <a href="http://sw.opencyc.org/2008/06/10/concept/en/CycLAssertion" class="cyc_term">CycLAssertion</a> is a KB-dependent collection, membership in which requires of a given CycL sentence that it has in fact been asserted to the KB. <a href="http://sw.opencyc.org/2008/06/10/concept/en/CycLSentence" class="cyc_term">CycLSentence</a> is also KB-dependent, as being a CycL sentence requires being composed (ultimately) out of <a href="http://sw.opencyc.org/2008/06/10/concept/en/CycLReifiedDenotationalTerm" class="cyc_term">CycLReifiedDenotationalTerm</a>s (and perhaps variables) -- i.e. terms that are currently reified in the KB. Conversely, <a href="http://sw.opencyc.org/2008/06/10/concept/en/Sentence" class="cyc_term">Sentence</a> is <i>not</i> a KB-dependent collection. <p/> See also <a href="http://sw.opencyc.org/2008/06/10/concept/en/KBDependentRelation" class="cyc_term">KBDependentRelation</a>.

Each instance of <a href="http://sw.opencyc.org/2008/06/10/concept/en/CycVocabularyTopLevelTopic" class="cyc_term">CycVocabularyTopLevelTopic</a> is an entry point (e.g. a topic you would see displayed first in a user interface) into the Cyc Vocabulary hierarchy of topics. Any of these top-level topics may have more general topics above them in the topic hierarchy (c.f. <a href="http://sw.opencyc.org/2008/06/10/concept/en/superTopics" class="cyc_term">superTopics</a>), but those more general topics will not serve as entry points unless they are asserted to be instances of <a href="http://sw.opencyc.org/2008/06/10/concept/en/CycVocabularyTopLevelTopic" class="cyc_term">CycVocabularyTopLevelTopic</a>.)
