+# RFC-4: Review 2
+
+## Review authors
+
+Chris Barnes <chris.barnes@gerbi-gmb.de>
+
+## Conflicts of interest
+
+None.
+
+## Summary
+
+Orientation is a useful piece of metadata which is easy to mistake through various registration and transformation steps.
+This RFC is sufficiently flexible to allow extension to different orientation types in future,
+while being simple to implement for the enumeration listed here.
+
+## Significant comments and questions
+
+N/A
+
+## Minor comments and questions
+
+Hyphens here are used as they would be in English.
+If/when the set of acceptable orientations is extended,
+we should be cautious that the existing hyphenated terms are not mistaken as a `kebab-case` convention;
+OME-Zarr uses `camelCase` and Zarr uses `snake_case` for multi-word keys.
+
+## Recommendation
+
+Accept.
