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

First we define the current life expectancy in japan.

%%Constant 
"Life expectancy in Japan" = 87
%

Lets calculate our remaining life expectancy based on our age.

%%Variable
"Years to life according to life expectancy" = "Life expectancy in Japan" - Age
%


!Compiling and testing the resulting knowledge base

Here defining a knowledge base using/compiling our two packages:

%%KnowledgeBase 
Life expectancy calculator (Japan)
