Oops! have the same number of results i.e. 1473 (counted the @prefix lines as results) -- Jos De Roo, AGFA http://www.agfa.com/w3c/jdroo/ Jos De_Roo/AMDUS/MOR/Agfa-NV/BE/BAYER@AGFA Sent by: public-rdf-dawg-request@w3.org 30/09/2004 02:08 To: "Steve Harris <S.W.Harris" cc: DAWG public list <public-rdf-dawg@w3.org>, (bcc: Jos De_Roo/AMDUS/MOR/Agfa-NV/BE/BAYER) Subject: Re: Result format size comparison Steve, I've been running that case data: http://www.ecs.soton.ac.uk/~swh/result-size/source.rdf query: [] q:select { (?uri ?name ?sa) }; q:where { ?uri a acm:Research-Area. ?uri support:has-pretty-name ?name }.

I'm only really interested in how efficient they are. They are all equally easy to generate. Also included is some rough calcualtion of the overhead of the different formats, compared to a baseline UTF8 format. - Steve
