 ### Process rules
 
-*Not implemented*
+* **Geometry**
+
+Wraps the WKT formatted geometry of a building in the `ST_GeomFromText()` function
+
+* **Quadkey**
+
+Determines the Quadkey tile of a building, based on the latitude and longitude of the centroid.
+
+* **RelationID**
+
+Determines the building relation OSM ID.
+
+* **StoriesAndFloorspace**
+
+Finds the `building:levels` tag in the attributes of the building or one of the building
+relations and saves it as number of stories. Calculates the floorspace of the building, based on the
+footprint size of the building and the number of stories.
