Careful; that'll only get you the days component¹. Even if it did what you were hoping for, you'll end up with off-by-one errors if they die close to their birthday due to the cumulative effects of leap years. You probably want: BIND(fn:years-from-duration(?date_of_death - ?date_of_birth) AS ?age_at_death) Best regards, Alex ¹ <http://www.w3.org/TR/xpath-functions/#func-days-from-duration> -- Alexander Dutton Linked Open Data Architect, Office of the CIO; data.ox.ac.uk, OxPoints IT Services, University of Oxford
