Government ontology?

Hi,
I'm looking for an ontology describing political bodies in Government, e.g., Parliament, Congress, Senate, etc...
It needs to describe the relation between a person and an office, legislature, geographical base (state, district, county, ...), etc...
Any pointers will be greatly appreciated!
