Any instance of the <WoTAssetName> Object shall implement the IWoTAssetType Interface.
The CreateAsset Method creates a new Object that implements the IWoTAssetType Interface organized by the WoTAssetConnectionManagement Object.
The DeleteAsset Method shall remove the Organizes Reference from the WoTAssetConnectionManagement Object and may delete the IWoTAssetType instance.
The components of the WoTAssetConnectionManagementType have additional references which are defined in Table 6.

CreateAsset creates a new Object that implements the IWoTAssetType Interface that can be used to upload the WoT TD file to the server. Once the upload is complete, the industrial asset becomes reachable via the OPC UA server. The WoT TD file uploaded fully defines the endpoint, protocol, and all asset tags to be mapped to OPC UA.
CreateAsset, when successful, returns the NodeId of the newly created Object and adds an Organizes Reference from the WoTAssetConnectionManagement Object.
Signature
CreateAsset(
[in] 0:String AssetName,
[out] 0:NodeId AssetId);
