   2. https://wiki.opendaylight.org/view/OpenDaylight_OpenFlow_Plugin:Backlog:Extensibility Michal R. is reviewing openflowplugin project extensnsibility (networkstatic, 17:13:09)
   3. questions about where the extensions will live, and who wil maintain them. networkstatic wanted to make sure there was ownership. (tbachman, 17:18:03)
   4. edwarnicke says that this won’t change for Helium, given that M5 (code freeze) is 1 week away. (tbachman, 17:18:21)
   5. networkstatic asks where there are examples of implementatino (tbachman, 17:22:58)
   6. Michal provided some examples on the wiki (tbachman, 17:24:02)
   7. Michal says that this is currently only tested in the OpenFlow plugin distributions (tbachman, 17:25:50)
   8. https://git.opendaylight.org/gerrit/gitweb?p=ovsdb.git;a=commit;h=50c3b5e41ce355dd4603a79004f2980a2f7cb5f1 Example Java API extension usage (networkstatic, 17:29:06)
   9. https://wiki.opendaylight.org/view/OpenDaylight_OpenFlow_Plugin:Backlog:Extensibility#Helpful_hints_for_reviewing_https:.2F.2Fgit.opendaylight.org.2Fgerrit.2F.23.2Fc.2F9393.2F Example robot framework and RESTconf usage (networkstatic, 17:30:25)
   10. Michal says that the result from the RPC only provides the result of sending. It doesn’t provide the result of the complete transaction. An error listener should be used to catch the full result, which are sent as notifications (tbachman, 17:36:49)
   11. The XID in the notification matches the XID of the original RPC (tbachman, 17:38:40)
