- Deleted the `rights_statement_url` slot definition as it is no longer needed. - Added multiple new slots including `has_legal_basis`, `has_statement`, `impose`, `pose_condition`, and `reviewed_through` with detailed descriptions and ontology alignments. - Updated existing slots to improve clarity and consistency, including renaming `close_mappings` to `related_mappings` in several definitions. - Enhanced the `require` slot with additional aliases for better usability. - Improved documentation and comments across all slot definitions to clarify their purpose and usage.
