-    notes: Migrated to ConservationPlan/ConservationReview pattern (Rule 53). However, simple follow_up_date is often just a date. Will migrate to temporal_extent in simple cases, or link to Review/Plan classes for complex cases. For StorageCondition/ConservationRecord, temporal_extent or a specific date slot is best. Wait, follow_up_date implies a future planned event. 'temporal_extent' usually means validity. Perhaps 'planned_for' + Event? Or just 'scheduled_for'? The revision suggests Roadmap/Plan. Let's archive follow_up_date and use temporal_extent on a Plan/Review entity linked to the main entity, or simply temporal_extent on the main entity if it represents a transient state. Actually, ConservationRecord has 'next_review_date' concept. Let's stick to the revision: Roadmap/Plan/Review.

-    notes: Migrated to temporal_extent (TimeSpan) in VideoTextContent.yaml. Note: The revision suggested linking to GenerationEvent then temporal_extent, but VideoTextContent already had generation_timestamp as a direct property. I migrated it to temporal_extent directly on VideoTextContent as per common pattern for simple timestamps, but it could also be part of the is_or_was_generated_by event. However, VideoTextContent *is* the result, so the timestamp refers to its creation. Using temporal_extent directly is valid. Slot archived.
