View model validation

Required field validation

• Empty Field Check: Ensures all configured properties have non-empty values.

• RegisterType: Must be specified and be one of: Primary, Secondary, Attributes, Associations, or Tracker.

• Category: Must be specified and be one of: Tags, Docs, General, or Physical.

Identification configuration

• IDColumn or IDExpression: At least one must be provided to uniquely identify records.

  If IDColumn is specified, it must reference a column that exists in the dataset headers.

• NameColumn (optional): If provided, must reference a valid column in the dataset headers.

Register type-specific validation

For primary register type:

• Class Definition: One of ClassColumn, ClassExpression, or ClassDefault must be provided.

  If ClassColumn is specified, it must reference a valid column in the dataset headers.

For attributes register type:

• AttributeNameColumn: Required and must reference a valid column in the dataset headers.

• AttributeValueColumn: Required and must reference a valid column in the dataset headers.

• AttributeUnitsColumn (optional): If provided, must reference a valid column in the dataset headers.

For secondary, tracker, and associations register types:

• No additional type-specific validation beyond common required fields.

Column reference validation

• All column references (IDColumn, NameColumn, ClassColumn, and so on) are validated against the actual dataset headers.

• If a referenced column was deleted or renamed, a validation error is reported.

• Ensures data mapping integrity between configuration and actual dataset structure.

Dataset structure validation

• For Attributes register type: Dataset must have defined columns or a file must be uploaded to provide column headers.

• Validates that required column mapping fields are not left empty when columns are available.

The validation output provides detailed error messages for each issue found, including:

• Which specific field has an error.

• What the validation rule requires.

• Whether a referenced column exists in the dataset headers.
