This is a basic demo about how to use and compile multiple packages into the same knowledge base. The basic scenario is described [here|Doc Package#Using multiple Packages for the same knowledge base or ontology]. The common package and more specifics for this demo are described [here|Multi-Package Demo].
!Defining the package
As before, we add this page to the package {{japan}}
%%Package japan
!Adding knowledge
Lets calculate our remaining life expectancy based on our age
%%Constant 
  Life expectancy in Japan = 87
%
%%Variable
"Years to life according to life expectancy" = 
%
!Compiling and testing the resulting knowledge base
Here defining a knowledge base using/compiling our two packages:
