Hi! I think that some of those who were in the meeting also might have slightly differing interpretations of what was said... I agree to that there were two alternative interpretations of "data stream" discussed, but as far as I understood those differed in the sense that 1) was an *infinite* stream, where the elements of the stream could somehow be *associated with time* (whether a timestamped triple, a timestamped graph, or just a stream where time is implicit from the arrival times of elements etc), and 2) was a *finite* stream of elements where *time is not necessarily an aspect*, e.g. triples from a data store being processed in a streaming fashion. I would be reluctant to at this stage limit ourselves to a specific model, e.g. RDF statements with a single timestamp each. Just my 2c.. /Eva On 12/11/2013 17:33 , Emanuele Della Valle wrote: > Hi Abram, > > I mean a list of tuples <s,t> where s is an RDF statement and t is a > non decreasing timestamp. > > Cheers, > > Emanuele > > -- > prof.
