Hi Frans,
I think it important to get the scope defined. The 2017 OWL-Time ontology went for full backward compatibility with OWL-Time 2006, which may cause problems, as the previous version has the TimeDate construct which, to me, is a not very clean compromise between coordinates and calendars.
So, first question: are both Euclidean ('straight') and Riemannian ('curved') coordinate spaces envisaged?
Second question: are both continuous (as in first question) and discrete ('nodes and arcs') reference systems envisaged?
Perhaps I have just defined quadrants to think about?

My colleague Mark Hedley has also just asked me to think about the difference between a Coordinate System and a Coordinate Reference System. "More grist to the mill" as we say in English.
