Creating ontologies

You can create the ontology that your organization requires for its projects.

Before you begin

You must have JazzAdmins privileges in Design Management.

About this task

An ontology defines the vocabulary, such as the classes and properties, that a domain uses. Classes describe the concepts of a domain, and properties define the relationships between the concepts. Ontologies can be used by multiple domains.

Procedure

  1. Open the Domains project area: Click the Home icon and under Design Management, click Domains.
  2. Create an ontology design resource: On the toolbar, click Designs, and under Create Design Resource, click Ontology.
  3. In the ontology editor, specify a unique ontology identifier and namespace prefix; then click Save.
  4. Add classes, restrictions, and properties to the ontology: Click the tab that corresponds to the type of element to edit; then add or edit the element.
  5. To assign object properties to class instances, in the ontology editor, under Object Property, click the object property. In the window that is displayed, in the Range field, select a class instance.

    Datatype and object properties are shared among the classes in an ontology until you assign them to specific class instances. For example, in an ontology for an organization, consider a class named PerformanceRating and an object property named LastRating. You can assign the LastRating property to the PerformanceRating class.

  6. Click Save.

Results

You can associate the new ontology with multiple domains. If you update the ontology, consider taking a snapshot after you complete your changes. You might have to update the domain association information for project areas, to ensure that the project areas are using the correct version of the ontology.
