Each instance of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rpPHhAOB1EdqAAAACs6hRXg" class="cyc_term">SpatiallyDisjointObjectType</a> is a collection C of spatial things (see <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjpUZwpEbGdrcN5Y29ycA" class="cyc_term">SpatialThing</a>), where each of the spatial things in C is spatially disjoint with the other spatial things in C. For example, the collection <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjaoJwpEbGdrcN5Y29ycA" class="cyc_term">Dog</a> is an instance of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rpPHhAOB1EdqAAAACs6hRXg" class="cyc_term">SpatiallyDisjointObjectType</a>, since dogs do not spatially overlap. Even pregnant dogs do not spatially overlap the pups they bear; rather, pregnant dogs contain their unborn pups. Other instances of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rpPHhAOB1EdqAAAACs6hRXg" class="cyc_term">SpatiallyDisjointObjectType</a> include <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rwVGrQ5wpEbGdrcN5Y29ycA" class="cyc_term">LatitudeLine</a>, <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvW4n1pwpEbGdrcN5Y29ycA" class="cyc_term">CompactDisc_Audio</a>, and <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rwR7UWZwpEbGdrcN5Y29ycA" class="cyc_term">PlanetaryBody</a>.

Instances of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvjSAy5wpEbGdrcN5Y29ycA" class="cyc_term">IBTFormatType</a> are collections of things which store or encode information. Each IBTFormatType is distinguished primarily by the physical format of its instances. For example, <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVkJAJwpEbGdrcN5Y29ycA" class="cyc_term">CompactDisc_Generic</a>, <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjgDpwpEbGdrcN5Y29ycA" class="cyc_term">HardcopyInformationBearingObject</a>, and <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjRW5wpEbGdrcN5Y29ycA" class="cyc_term">VideoTape</a> are all instances of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvjSAy5wpEbGdrcN5Y29ycA" class="cyc_term">IBTFormatType</a>. Non-examples include <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rwP2KM5wpEbGdrcN5Y29ycA" class="cyc_term">JazzMusic</a> and <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rv2L1npwpEbGdrcN5Y29ycA" class="cyc_term">StarTrek_TNG</a>, since these are distinguished primarily by the kind of information contained, rather than physical format. (edited ABelasco) type of information bearing thing classified by format IBTFormatType computer disk ComputerDisk A specialization of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjyH5wpEbGdrcN5Y29ycA" class="cyc_term">InformationStorageMedia</a>, this is the collection of all disks used for storage of information. This includes floppy disks as well as hard disks. SinglePurposeDevice A collection of devices each of which has a single <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rv-lujZwpEbGdrcN5Y29ycA" class="cyc_term">primaryFunction</a>. Each instance of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViXqpwpEbGdrcN5Y29ycA" class="cyc_term">SinglePurposeDevice</a> may have more than one function, but will have only one _primary_ function. For example, a car is a single purpose device because it has the primary function of providing transportation. Of course, a car can provide shelter as well as transportation; but a convertible with a badly torn roof still functions as a car (because its primary function is transportation) even though it does not function as much of a shelter. It is also possible for a <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViXqpwpEbGdrcN5Y29ycA" class="cyc_term">SinglePurposeDevice</a> to have other functions associated with it, even though they are not functions of that device per se. For example, if a car has a cigarette lighter, a clock, etc., those parts have their own functions, which are performed in the car and enjoyed by the users of the car while they are using the car. However, the functions of those devices (lighting cigarettes and telling time) are generally not considered to be the functions of the car itself. If someone utters the sentence `Fred used his car today' we would guess that Fred drove/rode somewhere in the car, and would be surprised/amused/annoyed/confused if we later discover that the speaker meant only that Fred used the car's lighter and the clock but didn't travel somewhere by car. single purpose device
