The country list is arbitrary and long, we confuse a change in government or even a change in name as separate countries (ex. British Honduras and Belize). Why list both when we can list them in one chronological "country"?
Instead of having a list of countries spanning from the dawn of history to the modern century, the country list should have all modern "countries" that link to, but do not include, predecessor governments. When we list separate governments, we list them either as separate currencies or a completely separate country. In my experience with the catalog, we should be able to access the modern country through the country list, and select predecessor countries and governments. A member should be able to choose whether he wants to see all coins issued by this country, or select the government or time period the coins were issued, thus eliminating the "1 country listed 5 times" issue.
After selecting a country, members will be able to choose what period their coin is from by drop down menu. These periods are separate listings, but not separate countries in the country list. On the top of the page, members can select the preceding or succeeding period, easily "scrolling" through the history of the country. If the member does not wish to separate the different periods, they may select a "see all" function which would list all coinage together.
Let me break this down. "Germany" will appear in the country list. Because the Federal Republic did not exist before 1949, the country will allow you to select the Third Reich, then the Weimar, than the Kaiserreich, then the individual states. Think of it as a timeline: the Reich and Federal coinage are two different species, but they are both Germany. They are not two separate countries.
In my experience, I think Numista will work best in a Wiki-style listing of countries. On this page for example, Numista lists "South Arabia" as a separate country. However, on the top of the page it shows the successor state South Yemen and predecessor state Aden. On Numista "South Arabia" would be a choice of selection under Yemen.
By allowing the drop-down menus, this may also pave way for colonial entities to be grouped together. Those who collect Portuguese colonial coinage, for example, may find these coins under Mozambique or Brazil, or have all the colonies listed under one sphere. I think of a new country list that will contain each colonial power, with each country containing separate colonies.
In short, we can solve two issues here: countries that change government, such as Austria, can be listed both separately and together, but will not appear more than once in the country list.
This is just a little thought. Any suggestions are warmly welcomed.
