Managing Individuals

You can update the Individuals of an ontology.

Use the Search tool to find specific Individuals.

This task shows you how to:

Add an individual

  1. In the Ontology, click the Individuals tab.
  2. Click
    The Create an individual dialog box appears.
  3. Type the Label and search the Type: any class (RDFS or OWL) from the ontology itself.

    The URI is generated on the fly from the Individual label entered (if English is selected), otherwise a UUID (Universally unique identifier) based URI is generated. The URI can be modified if needed.

    Note:
    • If not filled, the type of the individual will be set to Resource.
    • Labels entered are in the language you selected in your Preferences.

  4. Click Ok.

Update an individual

  1. In the Ontology, click the Individuals tab.
  2. Select an individual and update the fields.

    You can add a type (RDFS or OWL Class from the ontology itself or by default Resource).

    Note: The URI field is not editable.

  3. Optional: If you want to edit or display additional properties (other than built-in properties):
    1. Click > More
    2. In the Search properties field, enter the label of the property you want to add.

      An autocomplete list appears.

      Select the property you want to add and click .

      Note: The list of properties is retrieved from the current ontology and from all its prerequisite ontologies. The properties of the Ontology type are not proposed.

    3. In the property line, add the values.

      Depending on the property configuration, you can add Literal, or/and URI values.

      For example, you can add:
      • Literal value: a property whose values are literals. Click to add a literal value.
      • Resource value: a property whose values are URI resources.
      • Resource or Literal value: a property whose values are URIs or literals. Click to add a literal value. Enter a URI name (autocomplete) to add a URI.
      Note: If the property is functional, only one value can be provided.

    4. To delete an additional property, remove all its resources.
  4. Click Update.

    Click Reset to ignore changes since last update.

  2. Click next to the individual you want to delete.
