      metadata:
        description: >
          Additional VNF-specific attributes that provide metadata describing the VNF instance.
          
          These attributes represent values that are stored persistently in the VnfInstance structure for 
          consumption by functional blocks that invoke the VNF lifecycle management interface. They are not 
          consumed by the VNFM, or the lifecycle management scripts.
          
          Modifying the values of these attributes has no effect on the VNF instance, it only affects the 
          information represented in the VnfInstance structure.
          
          Metadata that the VNF provider foresees are expected to be declared in the VNFD. The declaration 
          of metadata in the VNFD can optionally contain the specification of initial values. See notes 2 and 4. 
          The VNFM shall accept requests to write metadata that are not declared in the VNFD.
          
          These attributes can be initialized with default values from the VNFD (see note 4) or with values 
          passed in the CreateVnfRequest structure (see clause 5.4.2.3.1).
          
          These attributes can be created, modified or removed with the PATCH method.

      extensions:
        description: >
          Additional VNF-specific attributes that affect the lifecycle management of this VNF instance.
          
          These attributes represent values that are stored persistently in the VnfInstance structure for 
          consumption by the VNFM or the lifecycle management scripts during the execution of VNF lifecycle 
          management operations. 
          
          All extensions that are allowed for the VNF are declared in the VNFD. The declaration of an extension 
          in the VNFD contains information on whether its presence is optional or required, and optionally can 
          specify an initial value. See notes 2 and 4. The VNFM shall reject requests to write extension attributes 
          that are not declared in the VNFD with a "422 Unprocessable Content" error response as defined in clause 
          6.4 of ETSI GS NFV-SOL 013.
          
          Modifying the values of these attributes has no direct effect on the VNF instance; however, the modified 
          attribute values can be considered during subsequent VNF lifecycle management operations, which means that 
          the modified values can indirectly affect the configuration of the VNF instance.
          
          These attributes can be initialized with default values from the VNFD (see note 4).
          
          These attributes can be modified with values passed in the request structures of certain LCM operations, 
          such as the InstantiateVnfRequest structure.
          
          Further, these attributes can be created, modified or deleted with the PATCH method.
          
          In addition, the provisions in clause 5.7 shall apply.

  VnfcResourceInfo:
    description: >
      This type represents the information on virtualised compute and storage resources used by a VNFC in a VNF instance.
      Depending on the form of virtualisation container of the VNFC:
        - For a VNFC based on VM, a reference to the corresponding VirtualCompute shall be provided, and
        - For a VNFC based on OS container(s), a reference to the Compute MCIO shall be provided. Hence, exposure of
          information by the VNFM to the NFVO is at the MCIO level.
      In addition, the references to the storage resources depend on the form of the VNFC:
        a) For a VNFC based on VM, storage resource identifiers shall refer to VirtualStorage resources, and
        b) For a VNFC based on OS container(s), storage resource identifiers shall refer to Storage MCIOs.

      NOTE 1:	ETSI GS NFV-SOL 001 specifies the structure and format of the VNFD based on 
              TOSCA specifications.
      NOTE 2:	A VNFC CP is "connected to" an external CP if the VNFC CP is connected to an 
              internal VL that exposes an external CP. A VNFC CP is "exposed as" an external 
              CP if it is connected directly to an external VL.
      NOTE 3:	The information can be omitted because it is already available as part of the 
              external CP information.
      NOTE 4: If only the value or the presence of this attribute is changed in the "VnfcResourceInfo"
              structure by an LCM operation occurrence, this does not represent a change that requires
              including a related "AffectedVnfc" structure in the VNF LCM operation occurrence notifications
              or the "VnfLcmOpOcc" structure related to this LCM operation occurrence.
      NOTE 5: Cardinality greater than 1 is only applicable for specific cases where more than one network attachment
              definition resource is needed to fulfil the connectivity requirements of the internal CP, e.g. to build a link
              redundant mated pair in SR-IOV cases.
      NOTE 6: When more than one netAttDefResourceId is indicated, all shall belong to the same namespace.
