Description

Method, computer-readable medium, system, and vehicle for providing vehicle data attribute provisioning of a vehicle to a vehicle external server Technical Field The present invention relates to a method for providing a vehicle data attribute provision of a vehicle to a vehicle external server. The invention also relates to a computer readable medium for providing a vehicle data attribute provision of a vehicle to a vehicle external server, a system for providing a vehicle data attribute provision of a vehicle to a vehicle external server, and a vehicle comprising a system for providing a vehicle data attribute provision of a vehicle to a vehicle external server. Background Current vehicles may transmit data to a back-end server based on events or rules. The software for transmitting the data is typically installed on the vehicle during vehicle production according to predetermined rules. Disclosure of Invention The object of the invention is therefore to provide a vehicle data attribute provision for a vehicle to a vehicle external server more efficiently. In particular, the invention is based on the task of providing metadata relating to at least one vehicle attribute from a vehicle to a vehicle external server more efficiently. The object is achieved by the features of the independent claims. Advantageous embodiments and developments of the invention emerge from the dependent claims. According to a first aspect, the invention features a method for providing a vehicle data attribute provision of a vehicle to a vehicle external server. The method may be a computer-implemented method and/or a controller-implemented method. The method comprises transmitting a subscribe message for writing vehicle data attributes from a software component of the vehicle to a vehicle data attribute database of the vehicle, generating by the vehicle attribute database of the vehicle data attribute provision from the subscribe message for writing the vehicle data attributes, and receiving by a synchronization component of the vehicle from a synchronization component of a server external to the vehicle a subscribe message for subscribing, in particular reading, the vehicle data attribute provision of the vehicle. The method further includes transmitting a subscribe message from the vehicle's synchronization component to a vehicle data attribute database of the vehicle for subscribing to the vehicle data attribute offer, transmitting the generated vehicle data attribute data offer from the vehicle's vehicle data attribute database to the vehicle's synchronization component, and transmitting the generated vehicle data attribute offer from the vehicle's synchronization component to a synchronization component of a vehicle external server to provide the vehicle's vehicle data attribute offer to the vehicle external server. Advantageously, the method may efficiently provide vehicle-specific vehicle data attribute provisioning to a vehicle external server. The vehicle data attribute provision may include metadata associated with at least one vehicle data attribute. Thus, the method may dynamically provide metadata associated with at least one vehicle data attribute. The vehicle external server always receives from the vehicle the current metadata transmitted by means of the vehicle data attribute provision of the vehicle. In other words, the method may synchronize the vehicle data attribute provision of the vehicle with the vehicle external server. This enables the vehicle external server to always keep track of the current overview of available vehicle data attribute supplies on a single vehicle level or cumulatively on a fleet of some vehicles. For example, the vehicle external server may determine a vehicle-specific selection of the vehicle data attribute using the vehicle data attribute provision. When the vehicle data attribute is read from the vehicle by the vehicle external server, unnecessary requests to some vehicles that do not provide the corresponding vehicle data attribute provision may be avoided, for example, because the use of the vehicle data attribute by the vehicle external server is restricted or prevented by the vehicle user. According to an advantageous embodiment, the subscription message may comprise a univocal attribute name, in particular a univocal, standardized attribute name, of the vehicle data attribute, and preferably a standardized data format may be associated with the vehicle data attribute, the standardized data format being used for storing the vehicle data attribute in a vehicle data attribute database. Thereby, uniform provision of the vehicle data attribute supply of the vehicle can be efficiently achieved. According to another advantageous embodiment, the software component may determine vehicle data properties from one or more in-vehicle network signals, and the software component may preferably adapt the one or more in-vehicle network signals to a standardized data format of the vehicle data p
