Managing Entities

An Entity is a core component of an ontology. This section provides a detailed guide on creating entities and defining their properties.

Defining Entity Properties​

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

Basic Information​

Entity Management

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

Schema​

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

  • Name: Property name
  • Type: Data type (Text, Integer, Float, Boolean, Date, Timestamp, etc.)
  • Primary Key: Whether the property is a key 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 converted into knowledge graph nodes and loaded.

  1. Select the Mapping tab in the entity detail panel.
  2. Select the dataset to connect.
  3. Map entity properties to dataset columns on a 1:1 basis.
