    - name: PerformVPDRecollection

          An api to check for FRUs replaced and if required, perform
          recollection of VPD data for them.

          - xyz.openbmc_project.Common.Error.InvalidArgument

    - name: DeleteFRUVPD
      description: >
          An api to delete VPD of a given FRU and set its Present property as
          false on DBus. This api is to be called before requesting VPD parser
          to collect VPD of any given FRU in case of concurrent maintenance.
      parameters:
          - name: inventoryPath
            type: object_path
            description: >
                Dbus path of the FRU whose VPD needs to be removed.
      errors:
          - xyz.openbmc_project.Common.Error.InvalidArgument

    - name: CollectFRUVPD
      description: >
          An api to collect VPD of a given FRU by launching the parser exe
          asynchronously. It can be used to collect VPD of any given FRU in case
          of concurrent maintenance. As a pre-requisite for this api,
          DeleteFRUVPD api needs to be called for that particular FRU. As this
          api makes async call to the parser, caller needs to register for
          Present property change signal for that FRU on DBus to ensure
          successful execution of VPD parser for that FRU. The caller is also
          suggested to have a timer of around two mins at their end and in case
          the present property is not set to true in that timeline, can mark the
          call as failed.
      parameters:
          - name: inventoryPath
            type: object_path
            description: >
                Dbus path of the FRU whose VPD needs to be collected.
