The document summarizes an event hosted by the AllSeen Alliance about programming the Internet of Things using APIs. It discusses how devices need standard APIs to communicate across brands and platforms. It introduces the AllSeen software framework, an open source project that provides APIs to allow IoT devices to discover, connect and communicate with each other regardless of manufacturer. The event will provide updates on AllSeen and encourage collaboration among developers and businesses to advance open standards for the IoT.

Ubiquitous connectivity promises to make devices “smart”
But ONLY if they speak the same language

Network topology matters
Direct communication
is fast, efficient, and
secure.
No need to go out to the
cloud to talk to the
device right next to you!“Coffee is done”
“Coffee is done”“Laundry is ready!”
“Laundry is ready!”

What are these “things”
of which you speak?
Without the right combination of hardware,
connectivity and software a “Thing” is just a
“Thing”. Ultimately it is software that makes a
“Thing” an Internet-of -Things Thing.

IoT Devices: how will they interact?
• IoT devices are characterized by the software they run so:
– When IoT devices talk to IoT devices it is software talking to software
• Well constructed software has clean boundaries between the internals of the
implementation and the external interfaces exposed to other software.
– We generally call these external interfaces Application Programming Interfaces (APIs)
– APIs are what makes it possible to incorporate existing functionality into new code
• APIs are how software talks to software

8. 9 September 2015 AllSeen Alliance 8
APIs – for IoT devices
• IoT devices should have APIs
– But these IoT devices are all so different
– Though often have very similar functions
• What APIs should IoT devices have?
– Some standard APIs
– Some device specific APIs

9. 9 September 2015 AllSeen Alliance 9
Standards
• What we don’t want:
– There’s an App for that thing
– And an App for that thing
– And yet another App for that thing
– …
• Devices that have similar functionality should expose the same APIs
– Every device with a clock should expose a set-clock API
– Every device that has a battery should expose a battery level API
– Manufacturers cannot differentiate by exposing necessary functionality in different ways

10. 10
IoT needs a framework to expose the various APIs of
connected devices in a consistent way.

The AllJoyn™ Project
An Open Source Framework for the
Internet of Things

12. 9 September 2015 AllSeen Alliance 12
December 2014 a group of companies formed the
AllSeen Alliance
• A nonprofit consortium dedicated to enabling the Internet of Things
• Hosts and advances an industry-supported software and services framework based on the
collaborative AllJoyn open source project.
• This collaborative open source framework enables hardware manufacturers and software
developers to create interoperable products that can discover, connect and communicate directly
with other devices, systems and services regardless of brand.
