Description

The base type of for all services generated by SDC in result of the service composition process by the service designer.

Allows for definition of common properties/attributes for all service-instance runtime objects.

Allows for composition (nesting) into higher-order services via substitution (i.e., solves the complex services problem)

Allows for the definition of service-level workflows via LCM interfaces

Properties

Name	Required	Type	Constraints	Description

Name	Required	Type	Constraints	Description
catalog_info	yes	onap.datatype.CatalogInfo	Only Catalog logic may assign and modify this property. For all other ONAP components and actors, it is read-only	Vital records assigned to and maintained by the model catalog for each node template: UUIDs, versions, etc.
classification	yes	onap.datatype.Classification

Attributes

Name	Required	Type	Constraints	Description

Name	Required	Type	Constraints	Description
instance_name		string		The name of the run-time instance in a deployment. MAY be different for different instances of the same template. This is unlike the tosca_name attribute of the tosca.nodes.Root node type, which is always the same for all instances of one template.

Capabilities

None for this abstract type. A concrete service type will have its capabilities defined with it and mapped to the capabilities of internal nodes in the service topology.

Requirements

None for this abstract type. A concrete service type will have its requirements defined with it and mapped to the requirements of internal nodes in the service topology.
