Raising Semantic Resource Discovery in IoT

Participants : Luigi Liquori, Marie-Agnès Peraldi Frati.

Within the standards for M2M and the Internet of Things, managed by ETSI, oneM2M, we are looking for suitable mechanisms and protocols to perform a Semantic Resource Discovery as described in the previous Subsection. More precisely, we are extending the (actually weak) Semantic Discovery mechanism of the IoT oneM2M standard. The goal is to enable an easy and efficient discovery of information and a proper inter-networking with external source/consumers of information (e.g. a data bases in a smart city or in a firm), or to directly search information in the oneM2M system for big data purposes. oneM2M ETSI standard has currently a rather weak native discovery capabilities that work properly only if the search is related to specific known sources of information (e.g. searching for the values of a known set of containers) or if the discovery is very well scoped and designed (e.g. the lights in a house). We submitted our vision in ETSI project submission “Semantic Discovery and Query in oneM2M” (currently under evaluation by ETSI) for extending oneM2M with a powerful Semantic Resource Discovery Service, taking into account additional constraints, such as topology, mobility (in space), intermittence (in time), scoping, routing ...
