A method of processing control data comprising: storing a first set of metadata in a transmitting device, storing a set of data for transmittal as a data stream in the transmitting device, transmitting the first metadata to a receiving device and then transmitting the data stream to the receiving device, parsing the received data stream at the receiving device according to the first metadata. The metadata may include the data stream format and/or a description of the data stream. The receiving device may comprise a big data appliance. The transmitting device may automatically update the metadata a configuration of the transmission device is changed. Updated metadata may be requested by the receiving device if an identifier that is not in the first metadata is found in the received data stream. The transmitting device may analyse the set of data (that forms part of the data stream) to generate analysis data and may add this data to the data stream. The data stream may comprise a time-stamp. The identifiers may identify a block, a module, a parameter, an event or an alarm. |
