Talk:RSP Query Semantics

From RDF Stream Processing Community Group

--Kia Teymourian (talk) 12:58, 4 June 2014 (UTC) I would propose that the in the interval-based semantics the graph/quad (data item object) should be annotated with a sequence of timestamps t=[t_i, . . . , t_f] where the intial timestamp t_i is the start time of happening and the final timestamp t_f is the end time. Similar to the event model proposed in [1]. Some of the use cases needs to mark the different times of happening and not only the start and end timestamps.
