2 Justification

As oneM2M based IoT platforms are being used in various domains, including smart city, there is a strong need to support any kinds of open data and various data policies. If data or data set is protected by one or more rights, the use of data from others requires a license from the data owner. This means that oneM2M system needs to provide means to add various data licenses to its resources containing such data. In addition, proper usage of data lincese, acknowledgement, and lifetime management (expiration, revoke, etc.) have to be guaranteeed.

The current oneM2M system does not support any means to acknowledge the use of data license and manage data based on given data license. Therefore, it is highly needed to find a mechanism to manage data license within oneM2M platform.
