== Implementation notes ==
+
−
*M2MBridge is an open source stack developed by the AMTEch team; it discovers and loads nodes modules implementing "M2MBridge plugin interface"(See [[Activities#Thing types|Thing types]]) tacking into account thing instances, activity(s) observation production configuration (See [[Activities#Observation production configuration|Observation production configuration]]) and M2MBridge credentials (See [[Access control#Actors|Actors]] and [[M2M Bridge#Edge Configuration|Edge Configuration]]).
