US Patent 7577649 Engine for validating proposed changes to an electronic entity

One implementation provides a method for analyzing the validity of a proposed change to an electronic entity. The method includes receiving the proposed changes to an electronic entity from an external device, and calculating a validity index based on a set of definable rules. The inputs to the calculation include quantified values that represent either contextual information about the proposed change or information about a user proposing the change, or some combination thereof. After the calculation of the validity index, the method includes deciding, based on the calculated validity index, whether to proceed further in applying the proposed change to the electronic entity.
