In the emerging Web of Things (WoT), a vast majority of devices do not consume nor produce RDF, notably because of their inherent constraints that prevent them from manipulating textual RDF syntax. However, it would be relevant to query against these sources irrespective of the (lightweight) formats they use, combined with other Linked Data. In fact the data these WoT devices expose contain crucial real-time information, and being able to tap directly into this information could enable smarter industrial applications. In this paper, we are interested in querying indiierently SPARQL endpoints, RDF documents, and non-RDF document exposed by WoT devices in a exible and extensible way. The core of this solution is an extension of SPARQL-LD. The SPARQL SERVICE clause is extended and can be used to query also non-RDF sources for which we know some RDF lifting mechanism.
