Examples

Transformo is run from a command line and configured using a YAML-file. The YAML-file follows a specific layout that aligns with the pipeline architecture of Transformo. The file has four mandatory sections: source_data, target_data, operators and presenters. In each section several elements can be added depending on the use case. Additional optional sections exists as well for running pre- and post-processing commands before the Transformo pipeline is executed.

In the following sections aspects of Transformo is demonstrated by examples of pipeline files and the output they produce when run in a terminal.
