Resource Types

In Rembrandt, resource types can be created at the "Types" page in the Organization component. When a new resource type should be created, several things can be configured:

  1. A name for the new resource type.

  2. The parent type. Used to built up the resource type hierarchy. All attributes of the parent class will be inherited. Each new type must at least be a sub-type of the root-class Resource.

  3. Choose if the class should be abstract. Abstract classes can not have any resources (resource instances). They are only used to refine the hierarchy, non-abstract sub-types of this type can have resource instances again.

  4. Set the attributes for the type. For each attribute, a data type can be selected. Additionally, it can be marked as required, meaning there can be no resource instance without a value for this attribute. Also, one attribute of the type can be defined as naming. When resource instances of this type are displayed, the value of the attribute marked as naming will be used instead of the resource id (e.g. for Human, the attribute name could be used).

Resource types can not be modified, to ensure a consistent structure of all resource instances of this type or sub-types. To delete resource types, open the respective detail-view and click Delete Type. Resource types can not deleted if there are sub-types defined or resource instances of this type.

Resource Instances

New resource instances can be created from either the detail-view of a resource type, or at the "Resources" page in the Organization component. The steps for creating a new resource are as follows:

  1. Select the resource type the new resource instance should be of. (Skipped if the resource is created from a resource type detail-view.)

  2. Fill in the attribute values. The attributes marked as required in the resource type will be enforced.

To modify or delete resource instances, open the detail-view of the resource instance and select the appropriate action.
