In a prior post I indicated that you do not want three separate triples = on the three separate pages. You merely want them to be visible and = editable from there. They could be in a back end store, and viewable = from various places. This may have architectural impacts, and there may be good reasons from = an implementers perspective why to keep it the way it is, and those = reasons may ultimately win out when all the tradeoffs are considered. I do hope that I think the developers' needs are second to users' needs. = After all, developers are building something FOR users, not [just] for = themselves. Easy for me to say, being a user and not a developer :-)) Michael=20 =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D Michael Uschold M&CT, Phantom Works=20 425 373-2845 mic...@bo... =20 =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D ---------------------------------------------------- COOL TIP: to skip the phone menu tree and get a human on the phone, go = to: http://gethuman.com/tips.html=20 -----Original Message----- From: Yaron Koren [mailto:ya...@gm...]=20 Sent: Friday, April 27, 2007 8:11 AM To: Kelly Jones Cc: sem...@li...; sw...@ai... Subject: Re: [swikig] [Semediawiki-user] Modeling "third party" = relations onSemantic Mediawikipage? [Now I don't know which of the two competing threads to respond to... I'm picking this one.] Someone brought it up before, but it's worth repeating: the thing that = makes free-form triples on semantic wikis (in my opinion) very = undesirable is having to deal with conflicts. To borrow from the = original example, if Bob's page lists a population size for Montana, and = Bill's page lists a different population, and Montana's own page lists a = third population altogether, how do you know which one to use? There are other arguments that can be made against free-form triples, = but in a sense they all stem back from this problem of data conflicts. -Yaron On 4/27/07, Kelly Jones <kel...@gm...> wrote: > It seems easy to modify Semantic Mediawiki to allow this?
