Example Suite for "Astronomical Coordinates and Coordinate Systems", version 1.0:

The following examples are produced by the modeler using a home-grown python 
utility called 'voefg' (Virtual Observatory Example File Generator).

Additional examples generated by an independently developed DSL-based package 
called 'jovial' can be found here: <URL>
