Datamapper advanced relationship question

[eluser]Haskabab[/eluser]
Yeah the relationship between the location and sublocation is easy.

But where I'm stuck is how to setup the relation between the location. And the different kind of locations.

A location can either be linked to:

1. Village
2. Cavern
3. Hideout
4. Fortress

these "children" all have their own table, and tables related to those. As i will write modules for them.

And the sublocation can either be linked to:

1. Shop
2. Hospital
3. Academy
4. Square
5. A lot more..

same goes for these children

Do you understand what I mean?
