Dear All

In attachment a proposition (in the sense of a graphical representation of open questions) concerning phases -> HW on  issue 422:

A link to Issue 245: Start/End vs Period of Existence should be added in my opinion at the bottom of issue 422 for the sake of documentation of former discussions.

For the current discussion about Phases see Issue 369 Timed relations.  Issue 414: CRMsci O14 initializes .

All the best
