Affine Coordinate System Transformationc back to ToC or Class ToC

IRI: https://w3id.org/gom#AffineCoordinateSystemTransformation

is defined by

An affine transformation between 3D Cartesian Coordinate Systems. An instance of this class links to exactly two gom:CartesianCoordinateSystem instances using resp. gom:fromCartesianCoordinateSystem and gom:toCartesianCoordinateSystem. Each instance of gom:AffineCoordinateSystemTransformation also links to one or multiple literals containing matrices defining the transformation. In the simplest example, there is only one such linked literal containing an entire 4 X 4 transformation matrix, linked with the gom:hasTransformationMatrix datatype property.
