           notice: '**Note:** This is the list of all processes specified by the openEO project. Back-ends implement a varying set of processes. Thus, the processes you can use at a specific back-end may derive from the specification, may include non-standardized processes and may not implement all processes listed here. Please check each back-end individually for the processes they support. The client libraries usually have a function called `listProcesses` or `list_processes` for that.'
