Yes, same ideas, and some common history eg see
http://dcpapers.dublincore.org/pubs/article/download/866/862 and
https://www.w3.org/2001/sw/wiki/images/0/00/SimpleApplication-SpecificConstraintsforRDFModels.pdf
although I suspect the JSON-LD @context angle has been under-explored so
far. JSON-LD is a little less appealing for IoT scenarios than for dataset
discovery because it makes (graph-extraction) parsing dependent on the
contents of a remote file, and IoT often needs to operate offline and
without leaking signals to the outside world. But that's a discussion for
elsewhere.

cheers,
