for its projects.
Before you begin
You must have JazzAdmins privileges in
Design

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
- Open the Domains project area: Click the Home icon
and under Design Management, click Domains.
- Create an ontology design resource: On the toolbar, click Designs,
and under Create Design Resource, click Ontology.
- In the ontology editor, specify a unique ontology identifier
and namespace prefix; then click Save.
- 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.
- 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.
- 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.
