The development of Goobi workflow started in 2004. In the meantime, many new functionalities have been added and the application has grown many times over. In order to maintain a good overview, but also to comply with established best practice for software development (Maven directory structure) and to make it even easier to keep the programme libraries used up to date in the future, we have massively revised the project structure. This should not result in any functional changes for the users. For us as developers, however, these are extensive interventions in everyday work and project organisation. If you notice any undesirable side effects when using Goobi workflow in the near future, which should certainly not be desired, please let us know.
