Open Interconnect Consortium has just released IoTivity, an open source framework for IoT, similar to AllSeen Alliance's AllJoyn framework. What are the differences between them, apart from IoTivity being based on CoAP and AllJoyn based on D-Bus? Are they interoperable?

One additional difference between these frameworks is how they treat Intellectual Property rights. AllSeen require from members not to sue other vendors which used AllJoyn for their product (Patent Non-Assertion Pledge).

Theyre completely different frameworks made by different companies that are both trying to achieve the same (or similar) thing. Its like comparing iOS to android.
They are not interoperable.

When it comes to supported transports, AllJoyn now supports more. It supports IP-related physical layers like WiFi, WiFi-Direct, Ethernet and Powerline. Also, it can support bluetooth with their gateway agent. Other radios such as Bluetooth LE, 6LowPan, ZigBee or Z–Wave are encouraged to be added.
The following is a snapshot from the QA session in Allseen official website.

Iotivity is easy to use, it provides C and C++ sdk for developing application on constrained devices. Quite easy to use for a basic application, provides GET,PUT ,POST and Observe functionality. Compared to Alljoyn it is faster and easier to develop apps on it.
