Assigning semantic types
You can assign entity, link, and property types a semantic type to identify the real-world meaning of the data. Ensuring that your semantic types are assigned accurately is important because it affects the organization and interpretation of your data.
Item and property types are aligned and interpreted based on what semantic type is assigned to them.
For example, a Car entity type and a Plane entity type can be assigned the Vehicle semantic type. Analyst's Notebook Premium aligns item types that are assigned the Vehicle semantic type, and interprets them as a type of vehicle.
You can assign semantic types to restrict the type of data that can be stored in a property type. Data types of property values must be consistent with the property's meaning.
You must assign a semantic type to a property type, unless all three of the following conditions apply:
- It is only used as a key, label, or description.
- It is not displayed in a report, the search results grid, or the chart data record.
- It has no search operators defined.
