# ThingsML and SenML

In KPN Things we use [ThingsML](/kpn-things/building-blocks/data-processing/thingsml-and-senml/thingsml.md) as a generic decoding and encoding service for the communication with Devices. SDKs from KPN Things are available to further help you implement ThingsML in your device.

We use [SenML](/kpn-things/building-blocks/data-processing/thingsml-and-senml/senml.md) within KPN Things and when forwarding the data to a destination.
