Entities are core components of an ontology. Learn how to create entities and define their attributes in detail.

Defining Entity Attributes​

When creating or editing an entity, configure the following items.

Basic Information​

Entity Management

  • Name: Entity name (required, uppercase English recommended)
  • Description: Description of the entity
  • Collection: Specify the collection to which the entity belongs.

Schema​

Define the properties that the entity will have. These should match the column structure of the linked dataset.

  • Name: Property name
  • Type: Data type (Text, Integer, Float, Boolean, Date, Timestamp, etc.)
  • Primary Key: Whether it's a key property that uniquely identifies the entity
  • Nullable: Whether the value can be empty

Dataset Mapping​

After defining an entity, you can map it to a Dataset containing actual data. Once mapping is complete, the dataset's data can be transformed and loaded as nodes in the knowledge graph.

  1. Select the Mapping tab in the entity detail panel.
  2. Select the dataset to link.
  3. Map entity properties to dataset columns 1:1.
