AccelerationClause acceleration clause The collection of all acceleration clauses. A type of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVi_0JwpEbGdrcN5Y29ycA" class="cyc_term">Obligation</a>. http://en.wikipedia.org/wiki/Acceleration_clause acceleration clauses A specialization of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rlvOL4mY1QdiY7KN-1Xb3Fw" class="cyc_term">NormativeSpecification</a>. Each instance of the collection <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVi_0JwpEbGdrcN5Y29ycA" class="cyc_term">Obligation</a> is specification of what some agent (related to the obligation via <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjWx5wpEbGdrcN5Y29ycA" class="cyc_term">obligatedAgents</a> (q.v.)) is obliged to do, or make true, for one or more other agents or possibly 'for' society in general. An obligation is the most general case of some agent owing something to another. Obligations may be undertaken in conjunction with various kinds of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVivo5wpEbGdrcN5Y29ycA" class="cyc_term">Agreement</a>s. Unlike an agreement, however, an obligation need not have a second known party (though some do). An obligation can exist and be understood without identifying another particular agent as the 'holder' of the obligation -- and that may be true, even if the beneficiary (<a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjXi5wpEbGdrcN5Y29ycA" class="cyc_term">obligationOwedTo</a>) can be identified. For example, assuming that parents have an obligation to care for their children, it is not clear with whom a parent has 'agreed' to take care of his or her child. Some common ways to incur an obligation are through social transactions (e.g. family duties, friendship, favors) or through financial transactions (e.g. a <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjD8ZwpEbGdrcN5Y29ycA" class="cyc_term">PaymentObligation</a>). In addition, obligations may be imposed on those who are subject to one or more instances of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViVx5wpEbGdrcN5Y29ycA" class="cyc_term">CodeOfConduct</a>, e.g. <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVkDMpwpEbGdrcN5Y29ycA" class="cyc_term">SportsRulesOf_BoxingSportsEvent</a> or <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVifDpwpEbGdrcN5Y29ycA" class="cyc_term">OfficeCodeOfConduct</a>. Obligation obligation AccelerationClause acceleration clause The collection of all acceleration clauses. A type of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVi_0JwpEbGdrcN5Y29ycA" class="cyc_term">Obligation</a>. ObjectType The collection of all collections that are &quot;object-like&quot; in at least one respect. A collection <code><b>COL</b></code> is object-like just in case there is some sense of 'part' according to which any (or nearly any) given proper part of an instance of <code><b>COL</b></code> is <i>not</i> itself an instance of <code><b>COL</b></code>; when this happens <code><b>COL</b></code> is said to be object-like with respect to that sense of 'part'. <p/> More precisely, for a collection <code><b>COL</b></code> to be an instance of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVirnZwpEbGdrcN5Y29ycA" class="cyc_term">ObjectType</a> it is sufficient that there be some specialization <code><b>PARTPRED</b></code> of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rwgfukKs8QdePzLB9nLNpTw" class="cyc_term">properParts</a> such that, for any <code><b>OBJ1</b></code> and <code><b>OBJ2</b></code>, if <code>(<a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViBBJwpEbGdrcN5Y29ycA" class="cyc_term">isa</a> <b>OBJ1</b> <b>COL</b>)</code> and <code>(<b>PARTPRED</b> <b>OBJ1</b> <b>OBJ2</b>)</code> both hold, then <code>(<a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViBBJwpEbGdrcN5Y29ycA" class="cyc_term">isa</a> <b>OBJ2</b> <b>COL</b>)</code> does <i>not</i> hold. (Also sufficient for <code><b>COL</b></code>'s being an object-type is that there be some specialization <code><b>INVPARTPRED</b></code> of the <i>inverse</i> of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rwgfukKs8QdePzLB9nLNpTw" class="cyc_term">properParts</a> (see <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvWHsNJwpEbGdrcN5Y29ycA" class="cyc_term">genlInverse</a>) such that <code>(<b>INVPARTPRED</b> <b>OBJ2</b> <b>OBJ1</b>)</code>, with everything else remaining the same as above.) Note that neither of the above sufficient conditions for <code><b>COL</b></code>'s being an object-type is strictly necessary: some exceptions are allowed. Thus as long as either one of the above conditionals holds in <i>nearly</i> all cases, <code><b>COL</b></code> should be considered an instance of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVirnZwpEbGdrcN5Y29ycA" class="cyc_term">ObjectType</a>. <p/> Here are two examples. Consider <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViVwZwpEbGdrcN5Y29ycA" class="cyc_term">Automobile</a>. Take an instance of that, say my car. Now consider one of the proper <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVj5FpwpEbGdrcN5Y29ycA" class="cyc_term">physicalParts</a> of my car, say the steering wheel. The steering wheel is <i>not</i> an instance of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViVwZwpEbGdrcN5Y29ycA" class="cyc_term">Automobile</a>. And the same would be true for any proper physical part of any car. So <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViVwZwpEbGdrcN5Y29ycA" class="cyc_term">Automobile</a> is an <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVirnZwpEbGdrcN5Y29ycA" class="cyc_term">ObjectType</a>. Consider <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjyV5wpEbGdrcN5Y29ycA" class="cyc_term">CalendarYear</a>. No proper <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvWn4OZwpEbGdrcN5Y29ycA" class="cyc_term">timeSlices</a> of a year is itself a year. So <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjyV5wpEbGdrcN5Y29ycA" class="cyc_term">CalendarYear</a> is an <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVirnZwpEbGdrcN5Y29ycA" class="cyc_term">ObjectType</a>. <p/> See <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVir35wpEbGdrcN5Y29ycA" class="cyc_term">StuffType</a> for the contrasting (though not disjoint) notion of being stuff-like. type of object 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 AccelerationClause acceleration clause The collection of all acceleration clauses.

A type of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVi_0JwpEbGdrcN5Y29ycA" class="cyc_term">Obligation</a>. type of temporally stuff-like thing A specialization of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVir35wpEbGdrcN5Y29ycA" class="cyc_term">StuffType</a> (q.v.) whose instances are all and only those collections that are temporally stuff-like. A collection <code><b>COL</b></code> is temporally stuff-like just in case every purely temporal part (see <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvWn4OZwpEbGdrcN5Y29ycA" class="cyc_term">timeSlices</a>) of an instance of <code><b>COL</b></code> is itself an instance of <code><b>COL</b></code>, unless it is a temporal part of a temporal granule of <code><b>COL</b></code> (see <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjaJJwpEbGdrcN5Y29ycA" class="cyc_term">granuleOfTemporalStuff</a>). <p/> More precisely, for a collection <code><b>COL</b></code> to be an instance of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVitN5wpEbGdrcN5Y29ycA" class="cyc_term">TemporalStuffType</a> it is both a necessary and sufficient condition that for any <code><b>OBJ1</b></code> and <code><b>OBJ2</b></code> (with <code><b>OBJ2</b></code> at or above <code><b>COL</b></code>'s temporal granularity level), if <code>(<a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViBBJwpEbGdrcN5Y29ycA" class="cyc_term">isa</a> <b>OBJ1</b> <b>COL</b>)</code> and <code>(<a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvWn4OZwpEbGdrcN5Y29ycA" class="cyc_term">timeSlices</a> <b>OBJ1</b> <b>OBJ2</b>)</code>, then <code>(<a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViBBJwpEbGdrcN5Y29ycA" class="cyc_term">isa</a> <b>OBJ2</b> <b>COL</b>)</code>. <p/> Consider <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVi0gpwpEbGdrcN5Y29ycA" class="cyc_term">WalkingOnTwoLegs</a>. Take an arbitrary instance <code><b>WALK</b></code> of this collection (say Miss America 2000's victory walk down the runway and back); and then take an arbitrary time-slice <code><b>SUBWALK</b></code> of <code><b>WALK</b></code> that subsumes at least one instance of (the <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjaJJwpEbGdrcN5Y29ycA" class="cyc_term">granuleOfTemporalStuff</a> for <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVi0gpwpEbGdrcN5Y29ycA" class="cyc_term">WalkingOnTwoLegs</a>) <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViYBpwpEbGdrcN5Y29ycA" class="cyc_term">TakingAStep</a> (say her trip back from the end of the runway). <code><b>SUBWALK</b></code> is itself an instance of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVi0gpwpEbGdrcN5Y29ycA" class="cyc_term">WalkingOnTwoLegs</a>. So <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVi0gpwpEbGdrcN5Y29ycA" class="cyc_term">WalkingOnTwoLegs</a> is an instance of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVitN5wpEbGdrcN5Y29ycA" class="cyc_term">TemporalStuffType</a>.
