The links will typically belong to a common subject area or set of subject areas. Some instances of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rwDdJkpwpEbGdrcN5Y29ycA" class="cyc_term">WebDirectoryPage</a> are pages within a portal site such as yahoo.com.

Others belong to (and are maintained by) other organizations or individuals. WebDirectoryPage ObjectType The collection of all collections that are "object-like" in at least one respect. A collection <code>COL</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>COL</code> is not itself an instance of <code>COL</code>; when this happens <code>COL</code> is said to be object-like with respect to that sense of 'part'. More precisely, for a collection <code>COL</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>PARTPRED</code> of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rwgfukKs8QdePzLB9nLNpTw" class="cyc_term">properParts</a> such that, for any <code>OBJ1</code> and <code>OBJ2</code>, if <code>(<a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViBBJwpEbGdrcN5Y29ycA" class="cyc_term">isa</a> OBJ1 COL)</code> and <code>(PARTPRED OBJ1 OBJ2)</code> both hold, then <code>(<a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViBBJwpEbGdrcN5Y29ycA" class="cyc_term">isa</a> OBJ2 COL)</code> does not hold. (Also sufficient for <code>COL</code>'s being an object-type is that there be some specialization <code>INVPARTPRED</code> of the inverse 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>(INVPARTPRED OBJ2 OBJ1)</code>, with everything else remaining the same as above.) Note that neither of the above sufficient conditions for <code>COL</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 nearly all cases, <code>COL</code> should be considered an instance of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVirnZwpEbGdrcN5Y29ycA" class="cyc_term">ObjectType</a>. 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 not 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>. 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 link page A collection of WWW pages. Each <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rwDdJkpwpEbGdrcN5Y29ycA" class="cyc_term">WebDirectoryPage</a> consists primarily of an ordered list of links into other web pages.

Some instances of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rwDdJkpwpEbGdrcN5Y29ycA" class="cyc_term">WebDirectoryPage</a> are pages within a portal site such as yahoo.com. Others belong to (and are maintained by) other organizations or individuals. WebDirectoryPage WorldWideWebPage-PCW <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rv-6kzpwpEbGdrcN5Y29ycA" class="cyc_term">WorldWideWebPage_PCW</a> is a specialization of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rv5L5vZwpEbGdrcN5Y29ycA" class="cyc_term">PropositionalConceptualWork</a> and <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rClGBHNkCEdmAAAACs2IKaQ" class="cyc_term">WorldWideWebPage_CW</a>. It is the collection of propositional works designed to be accessed on the <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvWQvpJwpEbGdrcN5Y29ycA" class="cyc_term">WorldWideWeb_DynamicIndexedInfoSource</a> via an implementation of the <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rwJobjpwpEbGdrcN5Y29ycA" class="cyc_term">HypertextTransferProtocol</a>. Instances of this collection include all world wide web pages with significant propositional context. Non-instances include web sites whose context is nearly entirely pictoral, musical, etc. world wide web page link page A collection of WWW pages.

WebDirectoryPage 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
