ComputerHardwareDeviceType SiblingDisjointCollectionType A <a href="http://sw.opencyc.org/2008/06/10/concept/en/KBDependentCollection" class="cyc_term">KBDependentCollection</a> of collections of collections (and thus an instance of <a href="http://sw.opencyc.org/2008/06/10/concept/en/CollectionTypeType" class="cyc_term">CollectionTypeType</a> and a specialization of <a href="http://sw.opencyc.org/2008/06/10/concept/en/CollectionType" class="cyc_term">CollectionType</a>). A sibling-disjoint collection type is such that its known (i.e. KB-represented) instances are collections that -- save for any that are related to each other by <a href="http://sw.opencyc.org/2008/06/10/concept/en/genls" class="cyc_term">genls</a> and any that are explicitly asserted to be exceptions (see <a href="http://sw.opencyc.org/2008/06/10/concept/en/siblingDisjointExceptions" class="cyc_term">siblingDisjointExceptions</a>) -- are disjoint from each other. More precisely, each instance <code>SIB</code> of <a href="http://sw.opencyc.org/2008/06/10/concept/en/SiblingDisjointCollectionType" class="cyc_term">SiblingDisjointCollectionType</a> is a collection of collections that has the following KB-dependent property: For any two known instances <code>COL1</code> and <code>COL2</code> of <code>SIB</code>, at least one of the following is known to hold: <pre> (a) (<a href="http://sw.opencyc.org/2008/06/10/concept/en/genls" class="cyc_term">genls</a> COL1 COL2) (b) (<a href="http://sw.opencyc.org/2008/06/10/concept/en/genls" class="cyc_term">genls</a> COL2 COL1) (c) (<a href="http://sw.opencyc.org/2008/06/10/concept/en/siblingDisjointExceptions" class="cyc_term">siblingDisjointExceptions</a> COL1 COL2) (d) (<a href="http://sw.opencyc.org/2008/06/10/concept/en/disjointWith" class="cyc_term">disjointWith</a> COL1 COL2) </pre> Moreover, note that if <code>MT</code> is a context (see <a href="http://sw.opencyc.org/2008/06/10/concept/en/Microtheory" class="cyc_term">Microtheory</a>) in which (i) both <code>(<a href="http://sw.opencyc.org/2008/06/10/concept/en/isa" class="cyc_term">isa</a> COL1 SIB)</code> and <code>(<a href="http://sw.opencyc.org/2008/06/10/concept/en/isa" class="cyc_term">isa</a> COL2 SIB)</code> hold and (ii) neither <code>(<a href="http://sw.opencyc.org/2008/06/10/concept/en/genls" class="cyc_term">genls</a> COL1 COL2)</code> nor <code>(<a href="http://sw.opencyc.org/2008/06/10/concept/en/genls" class="cyc_term">genls</a> COL2 COL1)</code> nor <code>(<a href="http://sw.opencyc.org/2008/06/10/concept/en/siblingDisjointExceptions" class="cyc_term">siblingDisjointExceptions</a> COL1 COL2)</code> is known to hold (see <a href="http://sw.opencyc.org/2008/06/10/concept/en/knownSentence" class="cyc_term">knownSentence</a>), then <code>(<a href="http://sw.opencyc.org/2008/06/10/concept/en/disjointWith" class="cyc_term">disjointWith</a> COL1 COL2)</code> holds by default in <code>MT</code>. For example, in <a href="http://sw.opencyc.org/2008/06/10/concept/en/BiologyMt" class="cyc_term">BiologyMt</a> both <a href="http://sw.opencyc.org/2008/06/10/concept/en/Person" class="cyc_term">Person</a> and <a href="http://sw.opencyc.org/2008/06/10/concept/en/Dog" class="cyc_term">Dog</a> are instances of the sibling-disjoint collection type <a href="http://sw.opencyc.org/2008/06/10/concept/en/BiologicalSpecies" class="cyc_term">BiologicalSpecies</a>, while neither (<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/Person" class="cyc_term">Person</a> <a href="http://sw.opencyc.org/2008/06/10/concept/en/Dog" class="cyc_term">Dog</a>) nor (<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/Dog" class="cyc_term">Dog</a> <a href="http://sw.opencyc.org/2008/06/10/concept/en/Person" class="cyc_term">Person</a>) nor (<a href="http://sw.opencyc.org/2008/06/10/concept/en/siblingDisjointExceptions" class="cyc_term">siblingDisjointExceptions</a> <a href="http://sw.opencyc.org/2008/06/10/concept/en/Person" class="cyc_term">Person</a> <a href="http://sw.opencyc.org/2008/06/10/concept/en/Dog" class="cyc_term">Dog</a>) is known to hold in that context; consequently, (<a href="http://sw.opencyc.org/2008/06/10/concept/en/disjointWith" class="cyc_term">disjointWith</a> <a href="http://sw.opencyc.org/2008/06/10/concept/en/Person" class="cyc_term">Person</a> <a href="http://sw.opencyc.org/2008/06/10/concept/en/Dog" class="cyc_term">Dog</a>) holds by default in <a href="http://sw.opencyc.org/2008/06/10/concept/en/BiologyMt" class="cyc_term">BiologyMt</a>.
