This is the collection of all and only those collections <code>COL</code> such that any thing's being an instance of <code>COL</code> depends on the current state of the <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjqoZwpEbGdrcN5Y29ycA" class="cyc_term">CycKB</a>. Such a <code>COL</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 "exists out there" in the KB-independent world. For example, <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvV281JwpEbGdrcN5Y29ycA" 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/Mx4rvViAoJwpEbGdrcN5Y29ycA" 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/Mx4rvu6KTZwpEbGdrcN5Y29ycA" 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/Mx4rv5ddsJwpEbGdrcN5Y29ycA" class="cyc_term">Sentence</a> is not a KB-dependent collection.
