Dear All,

Here my complete attempt to implement breaking the IsA between physical things and spacetime volumes. In the attached, the change tracking describes all changes between the previous version and the new one I could think of.

It implements the decisions of the last SIG Meeting.

In yellow are marked some properties that may have an added spatiotemporal formalization about the presence of parts.

Best,

Martin
