Class: Asset

An asset is the representation of a functional object with a technical function that is known to Industrial Asset Hub (IAH). Industrial Asset Hub (IAH) might want to manage the asset, to model its relationships with other assets, it might know the asset and ignore it,...

The only attributes that an instance of this class must provide are an ID to refer to it and the asset management state.

An asset instance might represent a physical object (like a Raspberry Pi or an application running on a system) or a virtual object (like a router in a network topology, no matter which physical device it is). In both cases an identifier for the object being represented is needed.

      Deployment dependent relationships (like "firmware image needs to be installed

      FunctionalObjects, but not Assets.

    description: 'An asset identifier is an asset attribute that provides enough information

      In some cases the ID attribute acts simultaneously as a reference for the asset
      instance and as identifier for the represented object, otherwise at least one
      asset identifier is needed.

      There can be multiple asset_identifiers with different goals. For example, the
      information of a metal nameplate can be used by a human-being to identify a
      device represented by an asset instance, but a software certificate provided
      by a device might help a software component identify the device in the network,...

      possibly even semantics.'
