Most of these projects +were for embedded network and measuring-probe devices. We started with +something called Clicon which was based on a key-value specification +and data-store. But as time passed new standards evaolved and we +started adapting it to XML, Yang and netconf. Finally we made Clixon +where the legacy key specification has been replaced completely by +YANG and using XML as configuration data. This means that legacy +Clicon applications do not run on Clixon. + +SDK +=== + +clixon sdk + +The figure shows the SDK runtime of Clixon. + +YANG and XML is at the heart of Clixon.
