Dear Martin, Thank you for the new version! As far as I can see some changes I suggested (and I thought was accepted?) for the last meeting is not part of your revised version. They are noted below.
I also suggested an updated version of the new paragraph and wonders a bit if two paragraphs are partly saying the same with different words. Details below.

Add sentence: This also means that overlapping land use rights, common among first nations, amounts to overlapping periods. > As the actual extent of an E4 Period in spacetime we regard the trajectories > of the participating physical things during their participation in an > instance of E4 Period, the open spaces via which they have interacted and the > spaces by which they had the potential to interact during that period or > event in the way defined by the type of the respective period or event, such > as the air in a meeting room transferring the voices.

Replace this paragraph with: As the actual extent of an E4 Period in spacetime we regard the trajectories of the participating physical things during their participation in an instance of E4 Period, the open spaces via which they have interacted and the spaces by which they had the potential to interact during that period or event in the way defined by the type of the respective period or event, such as the air in a meeting room transferring the voices. Since these phenomena are fuzzy, we assume the spatiotemporal extent to be contiguous, except for cases of phenomena spreading out over islands or other separated areas. Whether the trajectories necessary for participants to travel between these areas are regarded as part of the spatiotemporal extent or not has to be decided in each case based on a concrete analysis, taking use of the sea for other purposes than travel, such as fishing, into consideration. Consequently, instances of E4 Period may occupy each a limited number of disjoint spacetime volumes, however there must not be a discontinuity in the total timespan covered by these spacetime volumes. > Even though the substance of an instance of E4 Period is phenomena and hence > different from the substance of a spacetime volume, which is an aggregation > of points in spacetime, the real spatiotemporal extent of an instance of E4 > Period is regarded to be unique to it due to all its details and fuzziness. > Its identity and existence depends uniquely on the identity of the instance > of E4 Period.

Another proposal for this paragraph: We model E4 Period as a subclass of E2 Temporal Entity and of E92 Spacetime volume. The latter is intended as a phenomenal spacetime volume as defined in Hiebel et.al. (REFERENCE WITH YEAR). By virtue of this multiple inheritance we can discuss the physical extent of an E4 Period without representing each instance of it together with an instance of its associated spacetime volume. This model combines two quite different kinds of substance: an instance of E4 Period is a phenomena while a spacetime volume is an aggregation of points in spacetime. However, the real spatiotemporal extent of an instance of E4 Period is regarded to be unique to it due to all its details and fuzziness; its identity and existence depends uniquely on the identity of the instance of E4 Period. This multiple inheritance corresponds to the intuitions of natural language and enables unambiguous and effective modelling. > > Typically this class is used to describe prehistoric or historic periods such > as the “Neolithic Period”, the “Ming Dynasty” or the “McCarthy Era”, but also > geopolitical units and activities of settlements are regarded as special > cases of E4 Period.

To me, this paragraph seems to say partly the same as the paragraph starting with “As the actual extent of an E4 Period in spacetime we regard...” Is it only me or should these two paragraphs be combined? > > There are no assumptions about the scale of the associated phenomena.
