Wgraph:Sample Genealogy

This example demonstrates the power of wgraph in combination with

1. mediawiki templates
2. the Dynamic Page List extension (DPL).

We will guide you through a series of steps where a small genealogy tree is built.

We start with a straight forward approach and show how a very high level of abstraction can be reached.

Please go carefully through each step to understand the architecture of the final result.

First we define a small genealogy tree directly in WGL

• We concentrate on the semantics
• We do not use any coordinates or size attributes for the shapes
• we use nodetypes (male, female, info) to share common properties
• we use edgetypes (mother, father, married to, info) for the same purpose
• we mark undefined nodes in a special way

Thus we reach a fair level of abstraction.
