Field types define what kind of data a field can hold. NeoArc Studio supports 10 field types, with type specialisations that provide more specific formatting and validation for common data patterns.

Primitive Types

String Fields

Text values of any length. String fields support 56 type specialisations for common formats.

Integer Fields

Whole numbers without decimal points.

Number Fields

Decimal numbers with fractional parts.

Boolean Fields

True or false values. Boolean fields can have a default value and support validation rules like mustBeTrue and mustBeFalse.

Reference Types

Object Fields

Enum Fields

Reference to an enum schema, or inline enum values. Use enum fields for fields that must be one of a predefined set of values.
