Thanks Christian-Emil and Martin.
I will use then E4 and P7 (regretfully :-)
My impression is that the combination E92, P160 & P161 is a more elegant
solution. But, rules are
Well, it is not really about rules, but what you talk about. You need to
understand the implications: If you define the Byzantine Period to be
just geometric extent, you miss what defines it. If different extents
are debated, each one would be a different period.
we would like to be able to say: "I talk about the same period, but I
have a different chronology for it, because I found new evidence...". So
far, we believe we have solved that....
On the other side, any area within would be part of it, the life of
frogs in a ponds etc., because you could not distinguish that such
extents take their identity from a different phenomenon.
I do not share your opinion that under-specification of identity
conditions is elegant. I think it just creates the mess we are used in
conceptual modelling.;-)

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?
best,
Martin

Nevertheless, we used the term informally in the CRM. We could name E92 as
"abstract".
For me, some E92 are not abstract. E.g. I instantiate "Byzantine
Period" (it is somwhat difficult to place it in South America :-) :
<#ByzantinePeriod> <isA> <crm:E92_Spacetime_Volume>
<#ByzantinePeriod> <crm:P160_has_temporal_projection> <330-1700>
<#ByzantinePeriod> <crm:P161_has_spatial_projection> <#EsternEurope>
<#ByzantinePeriod> <crm:P161_has_spatial_projection> <#Levant>
<#ByzantinePeriod> <crm:P161_has_spatial_projection> <#NorthAfrica>
Also:
<#BronzeAge1> <isA> <crm:E92_Spacetime_Volume>
<#BronzeAge1> <crm:P2 has_type> <#BronzeAge-Concept>
<#BronzeAge1> <crm:P160_has_temporal_projection> <p?1>
<#BronzeAge1><crm:P161_has_spatial_projection> <#JapaneseIslands>
<#BronzeAge2> <isA> <crm:E92_Spacetime_Volume>
<#BronzeAge2> <crm:P2 has_type> <#BronzeAge-Concept>
<#BronzeAge2> <crm:P160_has_temporal_projection> <p?2>
<#BronzeAge2><crm:P161_has_spatial_projection> <#Scandinavia>
Should I worry ?
