Hi David,
5. The mapping system must allow request access (for subscribers) to be open and public. However, it is optional to provide confidentiality and authentication of the requesters and the information they are requesting. > > (1) I don't see any confidentiality requirements. The optional requirement for confidentiality was added for potential use cases where only some users are allowed to access information about others. Motivation: snooping mapping system informatation may be a way to track the behavior of other users. Regards, Michael -- Prof. Dr. habil.
