Hi! Please check the org.apache.tamaya.core.formatspackage
As far as I understand this is just another layer between the end format and a PropertySource. I fail to understand what it should be used for. What format should we define for those if any? What about other formats? Imo it doesn't add enough value. But happy to get it explained. Please list up use cases how this should later be used. If it is intended as 'base' part for helping other users to implement their own PropertySources, why don't we simply add a few abstract base classes into our extensions module? LieGrue, strub
