@permalmberg @edvin @nimakro I used to support a product called Alfresco which allowed both XML and properties. That was a while ago. Maybe various formats can be included? I ended up supporting the properties file because of the aforementioned help for support. nested properties weren’t really a problem because I had a dot notation. I think if the data structures are too complex, there’s probably a coding gap (different Providers with lighter configurations, etc)
