Let's check the detail of the first person by clicking the link of 'ENTITY_UUID'. The information is organized by Relations and Relationships. If the Relation has cardinality '[0..1]' or '[1..1]', it is shown as a form. If the Relation has cardinality '[0..n]' or '[1..n]', it is shown as a table.
In the Relationship blocks, you can check the detail of relationship by hitting the glass icon. A dialog will popup which shows the validity, the partner instance(s), and relationship attributes.
In the instance detail page, you can create, change, delete, and copy the instances. When you create a new instance, you have to make sure some entity relation attributes are given proper values. For example, you need to give values to the GENDER and TYPE attributes for a person, otherwise, the attribute-driven roles are disabled. After you assign the values, click the button 'Refresh Roles' in the upper-right of the entity relation block, the attribute-driven roles are then enabled.
In the bottom-left of the detail page, there is a button 'Add Relationship'. By clicking this button, a dialog will popup to let you first pick up a role and a relationship. After you confirmed the dialog, you can then assign partner instances in the detail page.
