Patent number: 8789009Abstract: Provided are an EMF model synchronization method and system. The system calculates a weight based on a hierarchy for an object identifier in a changed model, when the change of the model occurs in an EMF model which has an XML element path as an attribute. The system accumulates the calculated weight to a sum of weights. When the sum of weights becomes greater than the threshold value, the system simultaneously updates all models which are changed until the sum of weights becomes greater than the threshold value, thereby synchronizing change contents. As a hierarchy of an identifier changed on an XML path becomes higher, the weight is determined to have a larger value.Type: GrantFiled: May 27, 2010Date of Patent: July 22, 2014Assignee: Electronics and Telecommunications Research InstituteInventors: Joo Chul Lee, Tae Man Han
