Status: 2020-06-27: under review

The OpenDaylight project has implemented the RestConf interface according RCF8040. The previous in OpenDaylight implemented RestConf(-like) interface is supported too and both interfaces can be installed in parallel within the Apache Karaf container. Please see the documentation of NetConf project of OpenDaylight.  


This wiki shows difference between both interfaces based on examples.

The syntax is as defined by the vsCode/rest-client - sample code.


Info regarding RFC8040 and RFC8527

  1. RFC8040 defines RESTCONF
  2. The latest open-source implementation of RFC8040 is today in OpenDaylight Aluminium. However OpenDaylight Sodium and OpenDaylight Magnesium are good enough for our purposes.
  3. RFC8527 extends RFC8040 to support new datastores as defined in RFC8525, but RFC8527 does not make RFC8040 obsolete.
