RED Attribute Types
Data Types
All Attributes Types (or containers for them) themselves have a type, known as a RED data type. These are fundamental to the RED data (in particular its storage and processing). They probably look familiar from primitive types in many programming languages.
They differentiate things like
- Numeric (real) values (
Physical) - Text content (
String) - Boolean values (
Boolean) - Dates and times (
Datetime) - Numbers (
Number) - …and Integers (
Integer) - URLs, as strings for now (
URLText)
