VariedOrderCollection A <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvtppU5wpEbGdrcN5Y29ycA" class="cyc_term">CollectionType</a> and the collection of all and only those <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViAzJwpEbGdrcN5Y29ycA" class="cyc_term">Collection</a>s some of whose instances (or instances of instances, or instances of instances of instances, etc.) are of different "orders", where order is understood as follows. Let <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjaApwpEbGdrcN5Y29ycA" class="cyc_term">Individual</a>s be "zeroth-order" things, collections of (only) <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjaApwpEbGdrcN5Y29ycA" class="cyc_term">Individual</a>s "first-order", ..., and collections of (only) Nth-order things "(N+1)th-order". A more precise, recursive definition, then, is: a collection COL is an instance of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rNs-F0CChEdaAAABQ2rksLw" class="cyc_term">VariedOrderCollection</a> if and only if COL has instances INST1 and INST2 such that either (i) INST1 and INST2 are of two different fixed orders N1 and N2, (ii) INST1 is of the fixed order N1 and INST2 is a varied-order collection, or (iii) INST1 and INST2 are both varied-order collections. For example, <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rpJ-nSEkJQdeC8NLkYPDBBw" class="cyc_term">AbstractThing</a> is a varied-order collection since it contains both (zeroth-order) abstract individuals and (higher-order) collections. Other instances of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rNs-F0CChEdaAAABQ2rksLw" class="cyc_term">VariedOrderCollection</a> include <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjjo5wpEbGdrcN5Y29ycA" class="cyc_term">Intangible</a>, <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViAzJwpEbGdrcN5Y29ycA" class="cyc_term">Collection</a>, <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvtppU5wpEbGdrcN5Y29ycA" class="cyc_term">CollectionType</a>, and <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViA9JwpEbGdrcN5Y29ycA" class="cyc_term">Thing</a>. Note that (by clauses ii and iii) any generalization of a varied-order collection is varied-order; and (by clause iii) any (non-empty) specialization of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rNs-F0CChEdaAAABQ2rksLw" class="cyc_term">VariedOrderCollection</a> is varied-order. Note that <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rNooX_CChEdaAAABQ2rksLw" class="cyc_term">FixedOrderCollection</a> (q.v.) and <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rNs-F0CChEdaAAABQ2rksLw" class="cyc_term">VariedOrderCollection</a> do _not_ constitute a partition of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViAzJwpEbGdrcN5Y29ycA" class="cyc_term">Collection</a>: since the notion of order described above is not applicable to sets, <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvl2en5wpEbGdrcN5Y29ycA" class="cyc_term">Set_Mathematical</a> (e.g.) and its specializations are neither fixed-order nor varied-order collections. variable-order Cyc collection variable-order Cyc collections class of concepts belonging to a shared domain ConceptTypeByDomain Each instance of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4ret7qgOKgEdmAAAACs6hfSg" class="cyc_term">ConceptTypeByDomain</a> is a collection, all of whose elements can be considered concepts which belong to some domain of knowledge. For example, <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rWJzeaOKhEdmAAAACs6hfSg" class="cyc_term">FamilyRelationsConcept</a> is the collection that includes predicates, such as <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjj6ZwpEbGdrcN5Y29ycA" class="cyc_term">siblings</a> or <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjPcJwpEbGdrcN5Y29ycA" class="cyc_term">children</a>, collections, such as <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjhG5wpEbGdrcN5Y29ycA" class="cyc_term">FamilyCohabitationUnit</a>, and potentially other concepts that are part of the domain of family relationships. It is important to note that instances of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4ret7qgOKgEdmAAAACs6hfSg" class="cyc_term">ConceptTypeByDomain</a> are not quoted collections -- i.e., their elements are not the _terms_ used to represent the concepts, but instead are the concepts themselves.

A collection of collections. Each instance of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rxyRysnSxEdaAAACgyZzFrg" class="cyc_term">TemporalThingTypeByExistentialStatus</a> is a collection whose members in some way share an existential status, i.e., the extent to which they exist, fail to exist, or their existential history. TemporalThingTypeByExistentialStatus existential attribute

clarifying collection type ClarifyingCollectionType A specialization of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViAzJwpEbGdrcN5Y29ycA" class="cyc_term">Collection</a>. Instances are collections that are usefully invoked for purposes of resolving ambiguity and confusion that arise from the use of non-perspicuous languages. Suppose a human or other intelligent agent uses a language, such as a natural language, that is rife with ambiguity, and uses a word WORD of that language whose intended reference is unclear: in the context WORD might refer to THING1 or to THING2, but not both. One strategy for resolving this ambiguity is to find properties of THING1 and THING2, say P1 and P2, that distinguish them from one another, and ask the speaker whether by "WORD," s/he intended to refer to something with P1, or to something with P2. For example, the speaker might use the word "bank," and in response one might ask whether a financial institution or a piece of shoreline was meant. Clearly, what values of P1 and P2 are chosen cannot be arbitrary; asking whether the speaker meant to refer to a multi-individual agent versus a non-agentive place is not as effective as asking the speaker to choose between the "financial institution" and "shoreline" interpretations described above. Instances of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4r_4bScKNtQdiVw7XtX-HN0Q" class="cyc_term">ClarifyingCollectionType</a> just are those collections -- such as the collection of financial institutions -- that might plausibly be invoked to resolve cases of ambiguity of the kind described here. In particular, suppose TYPE1 is an instance of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4r_4bScKNtQdiVw7XtX-HN0Q" class="cyc_term">ClarifyingCollectionType</a> and TYPE2 is not, and THING is an instance of both TYPE1 and TYPE2. The fact that (<a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViBBJwpEbGdrcN5Y29ycA" class="cyc_term">isa</a> TYPE1 <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4r_4bScKNtQdiVw7XtX-HN0Q" class="cyc_term">ClarifyingCollectionType</a>) is a reason to prefer TYPE1 over TYPE2 when calculating possible clarifying properties for THING.

Intangible intangible The collection of things that are not physical -- are not made of, or encoded in, matter. Every <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViAzJwpEbGdrcN5Y29ycA" class="cyc_term">Collection</a> is an <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjjo5wpEbGdrcN5Y29ycA" class="cyc_term">Intangible</a> (even if its instances are tangible), and so are some <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjaApwpEbGdrcN5Y29ycA" class="cyc_term">Individual</a>s. Caution: do not confuse `tangibility' with `perceivability' -- humans can perceive light even though it's intangible--at least in a sense. For more on this issue, see the relevant #$cyclistNotes.

thing Thing <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViA9JwpEbGdrcN5Y29ycA" class="cyc_term">Thing</a> is the "universal collection": the collection which, by definition, contains everything there is. 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.)

Something is an instance of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjl_ZwpEbGdrcN5Y29ycA" class="cyc_term">SetOrCollection</a> just in case it is a collection (i.e. an instance of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViAzJwpEbGdrcN5Y29ycA" class="cyc_term">Collection</a>) or a mathematical set (i.e. an instance of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvl2en5wpEbGdrcN5Y29ycA" class="cyc_term">Set_Mathematical</a>). Instances of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvl2en5wpEbGdrcN5Y29ycA" class="cyc_term">Set_Mathematical</a> and instances of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViAzJwpEbGdrcN5Y29ycA" class="cyc_term">Collection</a> (and thus instances of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjl_ZwpEbGdrcN5Y29ycA" class="cyc_term">SetOrCollection</a>) share some basic common features. All instances of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViAzJwpEbGdrcN5Y29ycA" class="cyc_term">Collection</a> and all instances of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvl2en5wpEbGdrcN5Y29ycA" class="cyc_term">Set_Mathematical</a> (and thus all instances of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjl_ZwpEbGdrcN5Y29ycA" class="cyc_term">SetOrCollection</a>) are abstract entities, lacking spatial and temporal properties. Nearly all instances of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViAzJwpEbGdrcN5Y29ycA" class="cyc_term">Collection</a> (except "empty" collections) and nearly all instances of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvl2en5wpEbGdrcN5Y29ycA" class="cyc_term">Set_Mathematical</a> (except the empty set; see <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvfjtrpwpEbGdrcN5Y29ycA" class="cyc_term">TheEmptySet</a>) have "elements" (i.e. instances or members; see <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rwGWaK5wpEbGdrcN5Y29ycA" class="cyc_term">elementOf</a>); hence set-or-collections may stand to one another in generalized set-theoretic relations such as <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvZA-05wpEbGdrcN5Y29ycA" class="cyc_term">subsetOf</a> and <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViA45wpEbGdrcN5Y29ycA" class="cyc_term">disjointWith</a> (qq.v.). (It is this shared feature of having elements that provides the basic rationale for reifying the collection <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjl_ZwpEbGdrcN5Y29ycA" class="cyc_term">SetOrCollection</a>.) Nevertheless, sets and collections differ in two important ways. First, each collection is intrinsically associated with an intensional criterion for membership -- a more or less natural property (or group of properties) possessed by all of (and only) its elements. Collections are thus akin to kinds. In contrast, the elements of a set are not required to be homogeneous in any respect: any things whatsoever may together constitute the elements of a set. The second major difference between sets and collections is that no two distinct sets can be coextensional (i.e. have exactly the same elements; see <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVkIOpwpEbGdrcN5Y29ycA" class="cyc_term">coExtensional</a>). Sets can thus be identified purely on the basis of their extensions (see <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rwN2YGZwpEbGdrcN5Y29ycA" class="cyc_term">extent</a>). Collections, on the other hand, are individuated by their intensional criteria for membership. So collections that have exactly the same elements might nevertheless be distinct, differing in their respective membership criteria. (Note that the general relationship between collections and their "intensional criteria for membership" in the above sense is not something that is currently represented explicitly in the Knowledge Base (though this seems a worthwhile area for future work); still the <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViBCZwpEbGdrcN5Y29ycA" class="cyc_term">comment</a> and other "definitional" assertions on a given collection should ideally convey a reasonably clear and precise idea of its associated membership criterion.)

AtemporalNecessarilyEssentialCollectionType A collection of collections. Each instance <code>COL</code> of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rqEYnNVMqEdaSKAACs0x8nw" class="cyc_term">AtemporalNecessarilyEssentialCollectionType</a> (ANECT) is a collection satisfying three conditions: (1) <code>COL</code> is disjoint with (see <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViA45wpEbGdrcN5Y29ycA" class="cyc_term">disjointWith</a>) <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViAxJwpEbGdrcN5Y29ycA" class="cyc_term">TemporalThing</a>, (2) every instance <code>INST</code> of <code>COL</code> is an instance of <code>COL</code> essentially (i.e. <code>INST</code> is an instance of <code>COL</code>, and could not exist without being an instance of <code>COL</code>), and (3) condition (2) is a necessary truth about <code>COL</code>. Positive examples of ANECTs include <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViAzJwpEbGdrcN5Y29ycA" class="cyc_term">Collection</a>, <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVieEpwpEbGdrcN5Y29ycA" class="cyc_term">Integer</a>, and <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViAzZwpEbGdrcN5Y29ycA" class="cyc_term">Relation</a> (each of which is a collection of atemporals and is such that, necessarily, all of its instances are in it essentially). Negative examples include <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjpUZwpEbGdrcN5Y29ycA" class="cyc_term">SpatialThing</a> (though arguably it is necessary that all of its instances are essentially instances of it, it is not disjoint with <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViAxJwpEbGdrcN5Y29ycA" class="cyc_term">TemporalThing</a>) and <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rwP4FM5wpEbGdrcN5Y29ycA" class="cyc_term">UniqueAnatomicalPartType</a> (which, though disjoint with <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViAxJwpEbGdrcN5Y29ycA" class="cyc_term">TemporalThing</a>, has instances, such as <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjvDpwpEbGdrcN5Y29ycA" class="cyc_term">Heart</a>, that could exist even if they weren't instances of it; e.g. it might have been the case that every creature with a heart had at least two hearts). There are no known examples of Cyc-reified collections satisfying conditions (1) and (2) but not (3), but one can be contrived. Suppose that all of today's winning lottery numbers were primes. Now consider the collection: (<a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvrhK-JwpEbGdrcN5Y29ycA" class="cyc_term">CollectionUnionFn</a> (<a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjkdpwpEbGdrcN5Y29ycA" class="cyc_term">TheSet</a> <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjrdZwpEbGdrcN5Y29ycA" class="cyc_term">PrimeNumber</a> TodaysWinningLotteryNumbers)) This collection is clearly disjoint with <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViAxJwpEbGdrcN5Y29ycA" class="cyc_term">TemporalThing</a> and, by hypothesis, all of its instances are in it essentially (as each prime number is essentially a prime number). But this last fact is not necessarily true of this collection: the collection might have had instances that belonged to it only contingently (i.e. not essentially), as it might have been the case that one of today's winning lottery numbers was non-prime, and no number is such that it is essentially one of today's winning lottery numbers. When asserting that something is an instance or specialization of a given instance of ANECT, it is appropriate to do so in the <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4r3_SgQU2iEdaCwAACs0x8nw" class="cyc_term">UniversalVocabularyMt</a> (q.v.). Indeed, ANECT was specially defined to facilitate the movement of appropriate assertions to that microtheory.

NonAbducibleCollection The collection <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4roVp5xVzKEdiLrQAH6RYvVA" class="cyc_term">NonAbducibleCollection</a> is a sub-collection of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjl_ZwpEbGdrcN5Y29ycA" class="cyc_term">SetOrCollection</a>. Abductive inferences sometimes involve hypothesizing the existence of entities as part of the explanation of some assertion or set of assertions. Cyc will not hypothesize the existence of instances of the collections that are instances of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4roVp5xVzKEdiLrQAH6RYvVA" class="cyc_term">NonAbducibleCollection</a>. Roughly, abductive inferences consume conceptual / theoretical knowledge rather than produce it. So, <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rHQdVmB_TEdaAAABQ2rksLw" class="cyc_term">SecondOrderCollection</a> is an instance of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4roVp5xVzKEdiLrQAH6RYvVA" class="cyc_term">NonAbducibleCollection</a> because Cyc should be employing existing theoretical knowledge about instances of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rHQdVmB_TEdaAAABQ2rksLw" class="cyc_term">SecondOrderCollection</a> rather than hypothesizing new instances. non abducible collection

TimeIndependentCollection time independent collection A collection of collections. Each instance of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvzndCZwpEbGdrcN5Y29ycA" class="cyc_term">TimeIndependentCollection</a> is a collection whose membership cannot change over time.

fixed-order Cyc collection A <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvtppU5wpEbGdrcN5Y29ycA" class="cyc_term">CollectionType</a> and the collection of all and only those <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViAzJwpEbGdrcN5Y29ycA" class="cyc_term">Collection</a>s whose own instances are all of the same fixed "order", where order is understood as follows. Let individuals (i.e. instances of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjaApwpEbGdrcN5Y29ycA" class="cyc_term">Individual</a>) be "zeroth-order" things, collections of (only) individuals "first-order" collections, ..., and collections of (only) <code>N</code>th-order things "<code>(N</code>+1)th-order" collections. More precisely, then, a <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViAzJwpEbGdrcN5Y29ycA" class="cyc_term">Collection</a> <code>COL</code> is a <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rNooX_CChEdaAAABQ2rksLw" class="cyc_term">FixedOrderCollection</a> if and only if it is an <code>N</code>th-order collection (for <code>N</code> >= 1). Instances of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rNooX_CChEdaAAABQ2rksLw" class="cyc_term">FixedOrderCollection</a> include <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjaApwpEbGdrcN5Y29ycA" class="cyc_term">Individual</a>, <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rHIBS0h_TEdaAAABQ2rksLw" class="cyc_term">FirstOrderCollection</a>, <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rHQdVmB_TEdaAAABQ2rksLw" class="cyc_term">SecondOrderCollection</a>, <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rHUFI8h_TEdaAAABQ2rksLw" class="cyc_term">ThirdOrderCollection</a>, <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rHM37Dh_TEdaAAABQ2rksLw" class="cyc_term">FourthOrderCollection</a>, and all specializations of these. Specializations of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rNooX_CChEdaAAABQ2rksLw" class="cyc_term">FixedOrderCollection</a> include all of the preceding examples except <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjaApwpEbGdrcN5Y29ycA" class="cyc_term">Individual</a> and its specializations. Note that any #$quotedCollection (q.v.) is a fixed-order collection, since all of its instances are CycL expressions. Thus (e.g.) <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvZczwpwpEbGdrcN5Y29ycA" class="cyc_term">CycLDenotationalTerm</a> is fixed-order. It would be a mistake to infer, from the fact that the instances of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvZczwpwpEbGdrcN5Y29ycA" class="cyc_term">CycLDenotationalTerm</a> happen to denote things of different orders, that this collection is itself not of fixed-order. An example of a collection that is not fixed-order is <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rpJ-nSEkJQdeC8NLkYPDBBw" class="cyc_term">AbstractThing</a>, which is a varied-order collection since it contains both (zeroth-order) abstract individuals and (first-and-higher-order) collections. Note that, although they are mutually disjoint, <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rNooX_CChEdaAAABQ2rksLw" class="cyc_term">FixedOrderCollection</a> and <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rNs-F0CChEdaAAABQ2rksLw" class="cyc_term">VariedOrderCollection</a> (q.v.) do not constitute a partition of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViAzJwpEbGdrcN5Y29ycA" class="cyc_term">Collection</a>: since the notion of order described above is not applicable to sets, <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvl2en5wpEbGdrcN5Y29ycA" class="cyc_term">Set_Mathematical</a> (e.g.) and its specializations are neither fixed-order nor varied-order collections.

A disjoint collection type is such that its instances are collections that are all disjoint from one another. That is, each instance <code>DISCOLTYPE</code> of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvWPoRpwpEbGdrcN5Y29ycA" class="cyc_term">DisjointCollectionType</a> is a collection whose instances are mutually disjoint collections: no two instances of <code>DISCOLTYPE</code> have any instances in common.

It makes no sense to ask of an atemporal thing (e.g.) "When did it begin (or cease) to exist?" Examples of atemporal things include sets, collections, numbers, vectors, and certain "abstract structures" (such as the structure of a partial ordering); see <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjl_ZwpEbGdrcN5Y29ycA" class="cyc_term">SetOrCollection</a>, <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvxwC-ZwpEbGdrcN5Y29ycA" class="cyc_term">Number_General</a>, and <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjsEpwpEbGdrcN5Y29ycA" class="cyc_term">VectorInterval</a>. Note that while all atemporals are intangible, the converse is not true. Novels (see <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViJb5wpEbGdrcN5Y29ycA" class="cyc_term">Novel_CW</a>), languages, and geographical borders, for instance, are all intangible (i.e. they are not composed of or encoded in matter) but not atemporal, as they have a beginning and (in many cases) an end, and thus a temporal extent.

type of thing Collection A specialization of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjl_ZwpEbGdrcN5Y29ycA" class="cyc_term">SetOrCollection</a> (q.v.). This is the collection of all collections of things. Each <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViAzJwpEbGdrcN5Y29ycA" class="cyc_term">Collection</a> is a kind or type of thing whose instances share a certain property, attribute, or feature. For example, <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVkFc5wpEbGdrcN5Y29ycA" class="cyc_term">Cat</a> is the collection of all and only cats, and <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rwOckfJwpEbGdrcN5Y29ycA" class="cyc_term">BinaryFunction</a> is the collection of all and only functions taking two arguments. The notion of collection is fundamental to the Cyc ontology, and is thus difficult to define in a precise and substantive way. But it is instructive to compare it to the mathematical notion of a set (see <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvl2en5wpEbGdrcN5Y29ycA" class="cyc_term">Set_Mathematical</a>). Like a set, a collection is an <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rpJ-nSEkJQdeC8NLkYPDBBw" class="cyc_term">AbstractThing</a> (i.e. aspatial and atemporal) that is not an <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjaApwpEbGdrcN5Y29ycA" class="cyc_term">Individual</a> (cf.), but instead has elements (see <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rwGWaK5wpEbGdrcN5Y29ycA" class="cyc_term">elementOf</a>). Unlike a set, however, the elements or "instances" (see <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViBBJwpEbGdrcN5Y29ycA" class="cyc_term">isa</a>) of a given collection can vary from context to context, and it is possible for distinct collections to have exactly the same elements (i.e. to have the same <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rwN2YGZwpEbGdrcN5Y29ycA" class="cyc_term">extent</a>) with respect to a given context. For example, the (non-reified) collections "Chordate" and "Renate" are co-extensional in the context of the present-day actual world, but have differring extents with respect to hypothetical contexts in which there exist creatures having hearts but not kidneys. This difference is sometimes summarized by saying that sets are "extensional" things and collections are "intensional" things. Many, though by no means all, of the collections reified in the Cyc ontology correspond to natural kinds or classes. It is particulary useful to reify collections that are difficult to define precisely, but about which there are many common-sense rules and other things to state. For example, it would not be worthwile to introduce a constant 'WhiteCat', both because it's easy to define the collection of white cats in terms of more general, already-reified notions (e.g. '(<a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rwEcGC5wpEbGdrcN5Y29ycA" class="cyc_term">CollectionIntersection2Fn</a> <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVkFc5wpEbGdrcN5Y29ycA" class="cyc_term">Cat</a> <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rBjWwGHS-EdaAAACgyZzFrg" class="cyc_term">WhiteColor</a>)'), and because there's not much to say about that particular collection. <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rsX6vHnS6EdaAAACgyZzFrg" class="cyc_term">WhiteCollarWorker</a>, on the other hand, is a good collection to have reified, as it is hard to define precisely, yet is a collection about which there are many things to say. Some of the many reified specializations of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViAzJwpEbGdrcN5Y29ycA" class="cyc_term">Collection</a> are <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rHIBS0h_TEdaAAABQ2rksLw" class="cyc_term">FirstOrderCollection</a>, <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rwIE23ZwpEbGdrcN5Y29ycA" class="cyc_term">TimeDependentCollection</a>, and <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVirnZwpEbGdrcN5Y29ycA" class="cyc_term">ObjectType</a>.

A relation <code>RELN</code> totally orders a collection <code>COL</code> just in case <code>RELN</code> is reflexive, antisymmetric, and transitive on <code>COL</code>, and <code>COL</code> is connected with respect to <code>RELN</code> (i.e. for any instances <code>INST1</code> and <code>INST2</code> of <code>COL</code>, either <code>(RELN INST1 INST2)</code> or <code>(RELN INST2 INST1)</code> holds). For example, the integers are conventionally regarded as being ordered by <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViAr5wpEbGdrcN5Y29ycA" class="cyc_term">greaterThanOrEqualTo</a>, which totally orders <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVieEpwpEbGdrcN5Y29ycA" class="cyc_term">Integer</a>. Thus <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVieEpwpEbGdrcN5Y29ycA" class="cyc_term">Integer</a> is an instance of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rsY6gaGxxQdefg9tLUtQ-BQ" class="cyc_term">TotallyOrderedCollection</a>, and (since all integers are scalars) of its specialization <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4r91ZApkTvEdaAAACgye4oEQ" class="cyc_term">TotallyOrderedScalarIntervalType</a> (q.v.). totally ordered collection

A more precise, recursive definition, then, is: a collection COL is an instance of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rNs-F0CChEdaAAABQ2rksLw" class="cyc_term">VariedOrderCollection</a> if and only if COL has instances INST1 and INST2 such that either (i) INST1 and INST2 are of two different fixed orders N1 and N2, (ii) INST1 is of the fixed order N1 and INST2 is a varied-order collection, or (iii) INST1 and INST2 are both varied-order collections. For example, <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rpJ-nSEkJQdeC8NLkYPDBBw" class="cyc_term">AbstractThing</a> is a varied-order collection since it contains both (zeroth-order) abstract individuals and (higher-order) collections.

A collection of mathematical sets and collections whose elements are themselves mathematical sets or collections. A set or collection, SETORCOL, of sets or collections is an instance of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rk8dxOVcGEdaLwgACs0uFOQ" class="cyc_term">DisjointSetOrCollectionType</a> just in case the elements of SETORCOL are mutually disjoint -- that is, no two elements of SETORCOL have any elements in common.

An <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvytlApwpEbGdrcN5Y29ycA" class="cyc_term">ArbitraryUnion</a> is a collection whose extent is the arbitrary agglomeration of two or more other collections. Merely being a union of two other collections is not sufficient -- the union must be an arbitrary one in which it is difficult to state any interesting property about the union other than the specification of the collections which together make up its extent. For example, a concept like CoyoteOrRoadRunner would likely be an <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvytlApwpEbGdrcN5Y29ycA" class="cyc_term">ArbitraryUnion</a>, whereas <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViAkpwpEbGdrcN5Y29ycA" class="cyc_term">Person</a>, which is the union of #$MalePerson and #$FemalePerson is definitely not.

Instances of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rviPYH5wpEbGdrcN5Y29ycA" class="cyc_term">CollectionTypeType</a> are types of collection types, that is, collections whose instances are collections of (not necessarily first-order) collections.

This last example demonstrates that <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4r_3mf2qedQdmNjeDW39lDKA" class="cyc_term">NonEmptyCollection</a> is itself a time-dependent collection.
