Hi Pubudu, Thank you for your email. I hope at this point you may have tried out our IoT Server and the samples it provides. As you have figured out already, UMA is an Access Control Mechanism, that delegates management of access to personal information of users to themselves.
So in this scenario that we have envisioned, a user may have a bunch of devices they registered with IOT Server. For the purpose of this example, lets imagine one of these devices is a smart lock installed in the owner’s house, and their is a requirement for the owner to provide access to another party. With UMA, she can share control of the lock with the new tenant, by simply logging in to a device management dashboard. Lets assume the owner also has a baby monitor in the house and she can remotely monitor the video feed. She wants to share this video feed with a baby sitter, but she does not want to share control of the entire device, for example the third party shouldn’t be able to switch off/on the device. Going by the same mechanism quoted earlier, she can selectively grant/revoke to certain functionalities on the fly with the use of UMA. Another, usecase would be to group a set of devices or functions and share control or monitor data of the device as a whole. In the current implementation of the IoT Server, we already have support for grouping and sharing of devices, but this implementation is not UMA based. It is an implementation of our own. Going ahead with UMA would mean that we would have a more scalable approach to share access, and it would make things easier when dealing with sharing of devices between multiple groups with different access levels. We already have a UMA implementation in WSO2 Identity Server in POC form, deliverable would be to do the changes on CDMF side to accommodate the transition to UMA, for sharing of devices, groups and data.
