The Big question nobody asked

BUT it’s XML !!???

• XEP 322 http://xmpp.org/extensions/xep-0322.html

• W3C binary compression EXI http://www.w3.org/TR/exi/

• Very efficient

• Small devices can do binary stanzas without building xml only C

stubs

• And still valid XML

About Joachim Lindborg•Currently CTO of sust.se, I'm a technology enthusiast that believe that IoT is really about human interaction with systems adding value to life and that closed systems will die in favor for open one.

•For the past 15 years I have been working with system integration, especially at the intersection of energy and IT. I was one of the founders of homesolutions.se a start-up company integrating systems for supervision and maintenance of buildings.

•In the IT boom during the late 1990s I was employed by the swedish Utility Vattenfall to develop solutions for the smart home. It was an exciting time but it ended in disappointment. Now we are back again and with Internet of Things and a more stable technology I do believe that this time we will succeed. Right now I am working with companies in home security, heating and air conditioning, with energy companies and service developers in a project integrating all these technologies with sound business models for smart home services for energy control and efficiency.
