Deprecate operators/operations/rule types that have preferred alternatives

• Determine strategy for deprecating operators/operations/rule types
• Create tickets for deprecating necessary operators/operations/rule types

Some candidates for deprecation or replacement

Rule Types - Currently no rules are using these

• Not sure exactly how these would be used. They are using logic outside their rule builder:
  • Dataset Contents Check against Define XML and Library Metadata
  • Define Item Metadata Check
  • Value Level Metadata Check against Define XML
• We shouldn't currently have rules that only look at the define xml. Can probably be replaced by the current Rule Type: Dataset Metadata Check against Define XML. base_dataset_builder.get_define_xml_item_group_metadata/base_define_xml_reader.extract_domain_metadata and base_dataset_builder.get_define_metadata/base_define_xml_reader.read should probably be merged because they appear to be doing something very similar.
  • Define Item Group Metadata Check

Operations

• domain_is_custom (create library_ig_variable_attribute)
• domain_label (create library_ig_variable_attribute)
• expected_variables (create library_ig_filtered_variables)
• permissible_variables (create library_ig_filtered_variables)
• required_variables (create library_ig_filtered_variables)
• record_count (should come from extract_metadata)
• variable_permissibilities (create library_ig_variable_attribute)

Operators

• is_unique_set, present_on_multiple_rows_within
• is_ordered_by, is_ordered_set, target_is_sorted_by (subtle differences, could be combined)
• conformant_value_data_type, conformant_value_length, references_correct_codelist, uses_valid_codelist_terms (use rule type)

@gerrycampion can you describe what the alternatives would be for the rule types
