My example would be something like the Land Area of Serbia over time. It gets confusing when you add in the concept of Successor States etc but I'm trying to test my understanding of the Semantic Concept through various challenging scenarios.

What would be the ideal way to design the ontology so that I can do a query on different dates for the total Land Area say in 1990, 2005, 2010, 2013.

The last time I used Semantic Wiki was a few years ago but I ended up making the Wiki too confusing and unable to adapt to changes in time without losing previous information. Ie in 2008 Kosovo declared independence so pre 2008 the query should respond with the land area of Serbia+Kosovo but post 2008 it should respond with just the land area of Serbia.

To make it even more complicated, how do you then take in the concept of sovereignity recognition? For example the above scenario is valid for a person from the UK (me) as the UK has full diplomatic recognition of Kosovo, but Spain for example does not. So if I ran the query above but from the viewpoint of Spain then post 2008 it would respond with the land area of Serbia+Kosovo.
