A couple of comments from me: >> 1) which E2 is not an E4, even in a broad sense? I think the question here are whether "E3 Condition State" is the same as "E4 Period" and if "P5 and P9 consists of" are similar transitive properties. From a conservation point of view I was never comfortable with

Dear Francesco I agree with your analysis. My comment last night aimed at showing in Dan’s case the inconsistencies you explain in your message by a reductio ad absurdum. My questions are: 1) which E2 is not an E4, even in a broad sense? 2) which E94 (relevant, and not just purely abstract) is not

(Dan, resist, the cavalry is arriving, do you hear the trumpets? ) Sorry, that’s not convincing. E4 Period is a subclass of E92 Spacetime Volume, so every E4 is also an E92. There may theoretically be some E92 that are not E4, i.e. abstract subsets of R4 (sorry my email app does not allow supersc

Dear Dan, As Christian-Emil also pointed out, this is a wrong use of E92. The scope note says: "This class comprises 4 dimensional point sets (volumes) in physical spacetime". Do you regard that what makes up the identity and substance of the Byzantine Period is to be a set of points?

Dear Robert, Yes, this is up to the point. An example for E93 would be nice: typically, some reported situations, such as a museum object having been in display case xxx at least for this time-span, etc. Another important case are the declarative STVs (CRMgeo) we need in great number for app

Thank you Martin! If I can try to summarize my understanding, … A physical object isA space time volume that has a temporal projection that is equal to the time span between its beginning of existence and its end of existence. A period isA space time volume that has a temporal projection that i
