---------------------------------

             Summary: Dependency requirement type should match any target node.
                 Key: TOSCA-181
                 URL: https://issues.oasis-open.org/browse/TOSCA-181
             Project: OASIS Topology and Orchestration Specification for Cloud Applications (TOSCA) TC
          Issue Type: Bug
            Reporter: Luc Boutier


I think the definition of the Root node has something wrong: right now we have removed the Feature capability/dependency to replace it with a single dependency requirement of type tosca.capabilities.Root.
But actually no nodes defines the tosca.capabilities.Root capability. I think it's not very correct to satisfy a requirement by something that doesn't match the type of the requirement (and we don't have node directly defining the tosca.capabilities.Root capability).
To make it simpler and, I think, more correct, we should change the dependency definition so the requirement type is directly tosca.nodes.Root as I think any node can depends from another one.

Woud be:

  tosca.nodes.Root:
    description: The TOSCA Node Type all other TOSCA base Node Types derive from
    attributes:
      tosca_id:
        type: string
      tosca_name:
        type: string
    requirements:
      - dependency:
        type: tosca.nodes.Root
        lower_bound: 0
        upper_bound: unbounded
    interfaces: [tosca.interfaces.node.lifecycle.Standard | tosca.interfaces.node.lifecycle.Simple ]
