The predicate <a href="http://sw.opencyc.org/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 isogonic line IsogonicLine An <a href="http://sw.opencyc.org/concept/Mx4rmhpNoE--EdqAAAACs6hO_g" class="cyc_term">IsogonicLine</a> is an intangible curve on the Earth's surface (<a href="http://sw.opencyc.org/concept/Mx4rwCl_n5wpEbGdrcN5Y29ycA" class="cyc_term">EarthsTopographicSurface</a>) connecting points of constant magnetic declination.

Instances of <a href="http://sw.opencyc.org/concept/Mx4r-4nSRAttEdqAAAACs6hO_g" class="cyc_term">GeodesyConcept</a> are concepts which are included in the domain of <a href="http://sw.opencyc.org/concept/Mx4rwTnuWZwpEbGdrcN5Y29ycA" class="cyc_term">Geodesy</a>; therefore, <a href="http://sw.opencyc.org/concept/Mx4rzCm-HubNQdaO7ZipW2UPxw" class="cyc_term">Spheroid</a> models of the Earth, map projections, and coordinate systems would be instances of this collection.

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