EMF model synchronization method and system

An Eclipse Modeling Framework (EMF) model synchronization method executed by a processor, the method comprising:

• adding a changed first model to an update list, when the change of the first model occurs in an EMF model having an attribute in which the EMF model references a path of an object;
• calculating a weight based on a hierarchy for an object identifier in the first model;
• accumulating the calculated weight to a sum of weights;
• comparing the accumulated sum of weights with a predetermined threshold value;
• and
• updating all models, which are comprised in the update list, with a content of the change occurring in the first model, when the sum of weights is greater than the threshold value,
• wherein the weight based on the hierarchy is calculated to have a relatively high value, when the hierarchy is high, and the weight based on the hierarchy is calculated to have a relatively low value, when the hierarchy is low.

An Eclipse Modeling Framework (EMF) model synchronization system stored in a non-transitory computer-readable medium, the system comprising:

• a weight calculation unit configured to calculate a weight based on a hierarchy for an object identifier in a changed first model and to accumulate the calculated weight to a sum of weights, when the change of the first model occurs in an EMF model having an attribute in which the EMF model references a path of an object;
• a comparison unit configured to compare the accumulated sum of weights with a predetermined threshold value;
• an update list configured to store a list of changed models including the changed first model;
• and
• an update unit configured to update the changed models comprised in the update list with a content of the change occurring in the first model, when the sum of weights is greater than the threshold value,
• wherein as a hierarchy of an identifier changed on an Extensible Markup Language (XML) path becomes higher, the weight based on the hierarchy is calculated to have a larger value.
