      An open metadata repository has detected two metadata instances with the same identifier (guid). This is a serious error because it could lead to corruption of the metadata collections within the cohort. When this occurs, all repositories in the cohort delete their reference copies of the metadata instances and at least one of the instances has its GUID changed in its respective home repository. The updated instance(s) are redistributed around the cohort.
