SIE.4:3 - Forces
| Force | Tension |
|---|
| Automation | Matchers can surface many candidates, while their scores do not establish relation truth or permitted use. |
| Reuse | A general crosswalk is attractive, while relation adequacy can change with receiver, grain, interval, and accepted loss. |
| Precision | Exact relation kinds prevent overclaim, while sources may not support a complete formal characterization. |
| Coverage | Pressure favors filling every row, while unresolved and incompatible rows can be the most decision-useful result. |
| Direction | Transformation needs an orientation, while many conceptual relations are not symmetric or safely reversible. |
| Versioning | Stable mapping identifiers aid reuse, while endpoint meaning can change across source editions and profiles. |
