Each instance of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvWXYgJwpEbGdrcN5Y29ycA" class="cyc_term">ExistingObjectType</a> is a specialization of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVj27ZwpEbGdrcN5Y29ycA" class="cyc_term">PartiallyTangible</a> (q.v.). Moreover, each instance of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvWXYgJwpEbGdrcN5Y29ycA" class="cyc_term">ExistingObjectType</a> is a collection that is temporally stuff-like (see <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVitN5wpEbGdrcN5Y29ycA" class="cyc_term">TemporalStuffType</a>) but physically-spatially object-like (see <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVirnZwpEbGdrcN5Y29ycA" class="cyc_term">ObjectType</a>) -- i.e. object-like with respect to some physical-spatial part-whole predicate (e.g. some specialization of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4r8a2smPXcQdiEoJhcx65EiQ" class="cyc_term">properPhysicalDecompositions</a>). <p/> Consider the collection <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rwJaXepwpEbGdrcN5Y29ycA" class="cyc_term">BookCopy</a>. <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rwJaXepwpEbGdrcN5Y29ycA" class="cyc_term">BookCopy</a> is a specialization of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVj27ZwpEbGdrcN5Y29ycA" class="cyc_term">PartiallyTangible</a>. Further, <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rwJaXepwpEbGdrcN5Y29ycA" class="cyc_term">BookCopy</a> is temporally stuff-like: any one of the <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvWn4OZwpEbGdrcN5Y29ycA" class="cyc_term">timeSlices</a> of a given copy <code><b>COPY</b></code> of (say) &quot;Moby Dick&quot; is still a copy of &quot;Moby Dick&quot;.

Each instance of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjKJ5wpEbGdrcN5Y29ycA" class="cyc_term">EcologicalRegion</a> is a region having one or more characteristic ecosystems. From knowledge of those ecosystems, we can posit whether certain organisms can forage, reproduce, and live successfully there. Information about ecological regions typically also includes what kinds of organisms are in fact found there. In theory, any arbitrary continuous region could be analyzed as an ecological region, but most regions identified in practice have some kind of sameness or systematic interconnection in their topology, climate, and biology. Examples: the <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rwQBnu5wpEbGdrcN5Y29ycA" class="cyc_term">WesternDesertOfEgypt</a>, the <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvr5ZE5wpEbGdrcN5Y29ycA" class="cyc_term">GreatBarrierReef</a>, the <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvgEX1ZwpEbGdrcN5Y29ycA" class="cyc_term">Amazon_Region</a>. 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 oasis Oasis A specialization of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjKJ5wpEbGdrcN5Y29ycA" class="cyc_term">EcologicalRegion</a>.
