Abstract
This paper presents the \(\mu \)RDF store, a triple store designed for micro-controllers with limited memory, typically 8 to 64 kB. The \(\mu \)RDF store exposes a query interface inspired by SPARQL that supports basic graph pattern queries. Data is sent over CoAP and serialized in EXI, a binary format for XML.
The performances of its processing engine are demonstrated in a Web chat application where the \(\mu \)RDF store can be submitted queries. The application is available at: https://vcharpenay.github.io/urdf-amaa/.

Notes
- 1.
The demonstration presented in this paper also exploits this partitioning of the result set with MQTT, another IoT protocol: each mapping is published in a separate MQTT message.
