Managing Concepts (SKOS Thesaurus)

You can update the concepts of an ontology.

Use the Search tool to find specific concepts.

This task shows you how to:

Add a concept

  1. In the Ontology, click the Concepts tab.
  2. Click
    The Create a concept dialog box appears.
  3. Type the Preferred label.

    The URI is generated on the fly from the Concept Preferred label entered (if English is selected), otherwise a UUID (Universally unique identifier) based URI is generated.

    Note: Preferred labels entered are in the language you selected in your Preferences.

  4. Click Ok.

Update a concept

  1. In the Ontology, click the Concepts tab.
  2. Select a concept and update the fields.

    You can add a type (RDFS or OWL Class).

    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.

  1. In the Ontology, click the Concepts tab.
  2. Click next to the concept you want to delete.

    You can also click on the concept and click .

    A dialog box asking if you want to delete the concept appears.
