 ## How It Works
 
-UA Edge Translator solves the common "brownfield" use case of connecting disparate industrial assets with proprietary interfaces and translates their data into an OPC UA information model (ideally to one of the [standardized companion specifications](https://opcfoundation.org/developer-tools/documents/) from the [UA Cloud Library](https://uacloudlibrary.opcfoundation.org/)), enabling processing of the assets' data either on the edge or in the cloud leveraging a normalized, IEC standard (OPC UA) data format. This accelerates Industrial IoT projects and saves cost since the data doesn't need to be normalized in the cloud and makes use of the OT expertise often only found on-premises. For defining a mapping from the proprietary data format to OPC UA, the Web of Things (WoT) Thing Description schema (JSON-LD-based) or the IoT Plug and Play digital twins schema (also JSON-LD-based) is used. Additionally, the mechanism to provide the schema to the UA Edge Translator is also leveraging OPC UA. Therefore, for the first time, OPC UA is used for both the control and data plane for industrial connectivity, while previous solutions only used OPC UA for the data plane and a proprietary REST interface for the control plane.
