Adding a Relationship

You can add new relationships on the Overview Page or on the Source Relationships Page. When creating a new relationship an identifier is automatically generated, which conforms to SNOMED International rules and uses the namespace configured in the SNOMED CT Settings. The source of the relationship is the concept that you are currently editing. Relationship type and target concepts can be selected by using the search dialog.

Adding a Relationship on the Overview Page

Relationship types that conform to the concept model are automatically displayed in the Properties section of the Overview Page.

To define a relationship:

• Click the Add property button in the Properties Section to create new entry fields. You might have to scroll down to see the two new fields.
• Enter the relationship type in the first entry field. When you start typing a list of valid values is displayed from which you can select the relationship type.

Adding a Relationship on the Source Relationship Page

The New SNOMED CT Relationship Wizard allows defining any kind of relationship and modifying its settings, therefore using the Source Relationships Page is advised for more advanced users with specific requirements. The values for Characteristic type, Group, Union group, Modifier, and Relationship negated can be manually modified.

To add a new relationship from the Source Relationship Page you need to reveal the New SNOMED CT Relationship Wizard.

• Click on the Add relationship button in the top right corner to open the wizard. You can see the new relationship ID that was created.
