Our group has developed models of a composite girders, a bridge and a single family house. While the combination of the composite girder and the bridge is obvious at first sight, the challenge is to integrate the house into a common model. However, this is not how the integration should look like:

 

Or like this:

 

Let’s start from scratch and start with the three individual models.

If you want to jump straight to the result, this is what the combined ontology looks like. And this is the final model after all models have been integrated.

Have fun
