Of course you can save records (triples) in a Quad / Triple store with whatever URIs you choose, but at deployment time best you use URIs associated with your own Data Space and then owl:sameAs to the source. Basically, this is the pattern I wrote about when we started releasing DBpedia, NeuroCommons, Bio2Rdf, and MBZ to EC2. In all of these cases the de-referencable URIs exist in the instance owner's data space bound namespace thereby localizing the de-referencing tasks. > honestly? i dont even see the reasonw hy to copy this data on dogfood! > the entire point about semanti cweb is to be able to use data that's > distributed. > Yep. > copying will only create wrong duplicates once you change a bit of the > data, e.g. correct the spelling of my last name in the page. > Yep. > if its one source, then fine, the source is changed and its indexed > again if it has been copied.. everybody loses, i'd say :-) > Yes, "Data Access by Reference" is about not having to interact with "Data by Value" which requires localization of data in order to actually use the values :-) Kingsley > > Giovanni > > On Thu, Mar 19, 2009 at 3:42 PM, Knud Hinnerk Möller > <knud.moeller@deri.org> wrote: > >> Hi again, >> >> On 19.03.2009, at 14:58, Tom Heath wrote: >> >> >>> Hi Knud :) >>> >>> 2009/3/19 Knud Hinnerk Möller <knud.moeller@deri.org>: >>> >>>> Hi Tom, >>>> >>>> great stuff, and nice you're using some of our swc vocabulary! >>>> >>> Once a <http://data.semanticweb.org/ns/swc/ontology#DogfoodTsar> >>> always a <http://data.semanticweb.org/ns/swc/ontology#DogfoodTsar> ;) >>> >> It's an unliftable curse! >> >> >> >>>> I'd love to >>>> import the data into the dog food site - the more data we have there, the >>>> better.
