No, applicants are encouraged to design and detail distinct user paths for:

Providers of Information: Proposals should outline how information providers can submit, update, and share data, ensuring accuracy and usability.
Recipients of Information: Proposals should also include mechanisms for data recipients to access information, sharing, request updates, and be notified of any changes efficiently and securely.

This approach fosters creative and diverse solutions, ensuring that the final system meets the needs of all stakeholders effectively.
