- Removed obsolete slots: `has_or_had_custodian_observation`, `provider`, and `specificity_annotation`. - Updated `has_or_had_score` slot to use `SpecificityScore` class and modified its description and examples. - Added new slots: `end_seconds`, `end_time`, `has_archive_path`, `has_or_had_custodian_name`, `protocol_name`, and `protocol_version`. - Introduced a script `check_annotation_types.py` to validate the presence and structure of `custodian_types` in YAML files. - Added a script `update_specificity.py` to automate updates related to `SpecificityAnnotation` to `SpecificityScore`.

comments:
|
|
- Technique represents a procedure or method applied in heritage activities
|
|
- Always requires has_or_had_type to classify the technique
|
|
- Use includes_or_included for complex multi-step procedures
|
|
- Link to vocabulary terms (AAT) via has_or_had_identifier when applicable
