SIE.12:2 - Problem
Reusable semantic assets acquire users outside their original project. A term, class, relation, or mapping then carries assumptions into interfaces maintained by other participants. Changes can break those assumptions even when the shared file remains available.
One response is to require every participant to adopt one centrally controlled model. Another is to allow local changes without a recoverable relation to the shared meaning. Both can defeat useful reuse: the first can suppress necessary domain distinctions, while the second makes compatibility impossible to assess.
