OCPI 3.0

OCPI 3.0 will contain major changes, including changes to improve efficiency of OCPI. In November 2021 the Business Use Cases are published which are the basis for OCPI 3.0. This document is created to start from the business challenges and cases and from that point go to the functional use cases and finally specs. That way we ensure that the specs support the business issues and cases. The content is not written in stone and can be improved during the process towards OCPI v3.0. Feedback is always welcome.
