Dear Listmembers,
When designing historical maps spanning several centuries, we faced serious difficulties to consistently show the different categories of political entities in view of the evolution of political ideas. That is why, we are currently trying to work out an impartial and consistent solution allowing to depict all kind of polities throughout history regardless of the ideas of the time, as a formal model which in reality goes beyond the simple stage of historical geography. Thus we published the draft A FORMAL MODEL FOR HISTORICAL ATLASES AND HISTORICAL KNOWLEDGE which is the first part of our research. https://www.academia.edu/s/af65884c0f/a-formal-model-for-historical-atlases-... In the second step, we will define precisely the criteria for assigning properties to objects.
Persons interested can receive an invitation code in order to create their own graph in our model.
Sincerely
