Hi Saurabh pleased to meet you and wonderful that you are working the field of IoT and especially using xmpp for it. coposting this to the iot@xmpp.org list.The extensions published are as Arc pointed out totally free to use. They have been worked on for some time and there are some implementations around, you are free to use them and of-course also discuss changes. It is a hope that these published XEP's can be that source for a uniform IoT standard across implementations.
your site is nice looks promising (you need to redirect www... to the same adress as
http://iotfy.co/) let's discuss how the XEP's published works in your implementaion, on the
iot@xmpp.org list or offline if you prefer. just send me an email.
Introductions: (please help out with the work)
