So I guess the question is if you want to know say the temp recorded across multiple devices at a specific time how hard is it to query.
or if you have devices that quantize time (say 10 minute intervals) and someone asks for data at a 15 minute interval can you retrieve the data as reported at the earlier 10 min interval (eg. data recorded at 01:10 when 01:15 time is requested) Finally, do you have a link to the data cube vocabulary and any guidance to using it. I figure there must be pitfalls in there somewhere. ;) thx, Claude On Fri, Oct 7, 2016 at 10:37 AM, Dave Reynolds <[email protected]> wrote: > Hi Claude, > > We work with time sequence data in RDF, mostly for environmental > observation data.
