]> Xiaoshu Wang A Trivial Ontology for Geometry This file defines a trivial geometry ontology. This ontology is not intended to be designed to keep. It will likely be replaced by a future ontology defined by some mathematician rather than by an biologist like me. However, this ontology is designed to be used for some practical application, like to label the location and shape of a spot. 2005-08 Point The 'Point' is a location on an arbitrary plane with an implicit coordinate system. 1 1 Ellipse An 'Ellipse' represents an ellipsoid which axies are parallel to the implicit coordinate system. 1 1 x coordinate The 'x' labels the x-coordinate of a Point in the presumed coordinate system. y coordinate The 'y' labels the y-coordinate of a Point in the presumed coordinate system. x radius The 'rx' labels the 1/2 length of an ellipse's axis parallel to the x-axies of the presumbed coordinate system. y radius The 'ry' labels labels the 1/2 length of an ellipse's axis parallel to the y-axies of the presumbed coordinate system.
