Component: Concept

  • Concepts define data types and can be referenced across datasets, providing textual information, topic association, data type, attributes, properties, default values, and table mappings.

  • Each concept has a unique ID and can inherit properties from another concept using the extends attribute.

  • Concepts can be associated with topics, have attributes for additional information, properties for instance-specific details, and default values.

  • A concept's data type can be one of: string, float, integer, boolean, date, or another concept.

  • Concepts can be mapped to tables containing their values and non-constant properties for data storage and retrieval.
