DATA_TYPE_ALIASES =

Wire-format aliases for the data_type string. Used by #data_type to canonicalize the raw value before exposing it.

  "TRANSLATABLE_STRING_TYPE" => :translatable_string,
  "REAL_MEASURE_TYPE"        => :real_measure,
  "INTEGER_MEASURE_TYPE"     => :integer_measure,
  "INT_MEASURE_TYPE"         => :integer_measure,
  "REAL_TYPE"                => :real,

PARSED_DATA_TYPE_BLOCK =

── Computed fields with block-form readers (synthetic: true). Blocks are evaluated via instance_exec on the entity, so they have access to private helpers without send dispatch. data_type is NOT a DSL field — the model's #data_type method returns a symbol (:real, :string, etc.) for callers. The wire- format string ("REAL_TYPE") comes from parsed_data_type.to_s and is emitted explicitly by Exporters::Json#property_node.

lambda {
  Opencdd::DataType.parse_or_string(properties[Opencdd::PropertyIds::MDC_P022])
}
DATA_ELEMENT_TYPE_BLOCK = 
lambda {
  @property_data_element_type ||=
    Opencdd::PropertyDataTypeElement.parse(properties[Opencdd::PropertyIds::MDC_P020])
}
