Re: [topbraid-users] Time Interval Functions

[Scott Henninger]

Rich, there are a number of SPARQL and TopBraid functions that work on xsd:time and xsd:dateTime  for SPARQL, see http://www.w3.org/TR/sparql11-query/#func-date-time, including year(), month(), day(), hours(), timezone(), etc. TopBraid also has functions for duration, formatting date strings, etc.  I.e. you can convert a dateTime string to a date string using dateFormat().  See TopBraid Composer Help TopBraid Composer > Reference > Functions Overview -- Scott On 2/11/2014, 10:40 AM, Rich Keller wrote: Hi. I have been trying to do some temporal arithmetic in SPARQL and have stumbled upon what I believe are time periods or time intervals.  For example SELECT ?a ?aa WHERE { BIND (("08:15:00"^^xsd:time - "10:15:00"^^xsd:time) AS ?a) BIND (("2012-09-08T08:15:00"^^xsd:dateTime - "2012-09-07T10:15:00"^^xsd:dateTime) AS ?aa) } Results: ?a -> -P0Y0M0DT2H0M0.000S  (negative 2 hours) ?aa -> P0Y0M0DT22H0M0.000S (positive 22 hours) My question: Is there any way to operate on these time periods? In particular, suppose I want to convert the length of these these periods into seconds or minutes. smf:duration does something similar, but it works on xsd:date values, and not time periods. If smf:duration took xsd:dateTime or xsd:time arguments, that would be helpful. Do you have any pointers to functions that extract information from these time periods? I suppose I can figure a way to do the arithmetic myself using days(), hours(), minutes() functions, but I would prefer to avoid that.
