1. A method for implementation of a processing procedure on an object allocated to an object category as an instance of an object type in a computer system, comprising the steps of: breaking the object into separately processable, hierarchically classifiable sub-objects as instances of corresponding sub-object types; processing at least a part of the sub-objects with respective, predetermined partial processing procedures specific to each sub-object type; processing results obtained from processing the sub-objects and combining the results via a functional relationship in a processing procedure of higher rank than the partial processing procedures; and deriving an object-specific processing result for the processing procedure, wherein in order to implement the partial processing procedures specific to each sub-object-type, object attributes or attributes of other sub-objects are temporarily made available.
