You can align model element identifiers between migrated Eclipse
Modeling Framework (EMF) models by comparing them to an identifier mapping
database. After you align the migrated models, you can compare, merge, or
combine them.
Before you begin
You must have created a model element identifier database.
About this task
To align migrated model element identifiers:
- In the Model ID Alignment view, from the Operation list,
select Align model element IDs using ID mapping database.
- Click Add Files and browse to the location
of your model files. Select one or more model files. Each model file that
you add is aligned with a separate database file that you previously created.
- To check if any of your models have elements with the same identifier,
click Check Duplicate IDs.
- To select the location to save the aligned models, in the Save
Location of Models with aligned IDs area, specify the location.
Note: For each set of models that you align, you should specify a new
save location, so that you do not overwrite any previously aligned models.
- To specify a different model element identifier database folder,
click Browse and specify a new folder location.
- To specify an alternate database file, click Select
Alternate DB File and browse to the location of your database
file.
Note: You must specify an alternate database file if the
root identifier of the model that you are aligning does not match the root
identifier of any database file.
- Click Align Model Element IDs.
