Description

Currently Rya does not provide a Function that determines whether two temporal literals are within a given period of time of one another. This is extremely useful for filtering on query results that occurred within a fixed period of time of a given instant. Currently, if one attempts to form the following filter Filter(?time1 - ?time2 < "24"^^xsd:hour), an exception will be thrown if ?time1 and ?time2 are date time literals. I propose implementing a Function that takes in two temporal literals, an integer and a time unit and determines whether the date times are within the prescribed period of one another.
