title: IoTivity vs AllJoyn - what is the difference?
body: <p>Open Interconnect Consortium has just released <a href="https://www.iotivity.org/">IoTivity</a>, an open source framework for IoT, similar to AllSeen Alliance's <a href="https://allseenalliance.org/">AllJoyn</a> framework. What are the differences between them, apart from IoTivity being based on CoAP and AllJoyn based on D-Bus? Are they interoperable?</p>
