Windows in S2S operators #78

Open AlasdairGray opened 7 years ago

AlasdairGray commented 7 years ago

The text in Section 4.4 argues for not needing to define windows for streaming operators. The examples 6&7 then go and give example queries with windows. Why was the following form of query not used for Example 6?

SELECT ?room ?person
FROM STREAM ex:social
WHERE {
  ?person :isIn ?room
}

The existing proposal seems to require a lot of syntax for no benefit.

I think it is only for keeping the same syntax as when window boundaries are specified. I think your version can be used as well, which could be more convenient.

The syntax without the windows would better fit our non-functional requirements
