Device Platform Experience

demo

Device paradigm

App paradigm

A device might need to Determine what’s changed in a folder Update contents of a folder Subscribe to real-time notifications Publish transient or persistent properties Communicate with other devices

And present itself to the user as A separate application or service that

interacts with all Mesh content A device in the Device Ring that can be

configured per folder

Interacting With Mesh Services

A Tale Of Two Paradigms

Delegated Authorization (Simplified)

This user wants to authorize me

Yes indeed!

Here’s your token

Do you really want to authorize this app?

Device Roadmap

Today (Live Framework CTP) Delegating authorization to apps/services is

easy Creating a new device is not supported

Future: thinking about how to support new device types with the right Programmability UX integration Cross-platform support

Summary

The Mesh is most interesting with a wide range of devices

We will support a full device model in the long term

For now, delegated authorization enables many scenarios
