From private IRC, with permission. <DanCon> how much longer are you in BOS? I think a model theory for RDF would take about 2 hours for us to work out. Maybe if I explained it to your satisfaction, you could explain it to the rest of the WG (and the community)? <danbri> i'm here another week, then a week west coast for sw/rdf stuff <danbri> I don't think your 'textbook' crack is entirely fair, though I'm perfectly happy admitting I'm still catching up on the KR reading list <danbri> If you think it'd take 2 hours, maybe we could try sometime next week. Any time after tues would do for me. <DanCon> fair: maybe not. What frustrates me is: you understand FOL perfectly well, but you go on about how "people understand 'there exists' in different ways". Yes, people are confused. That doesn't change what FOL is. <DanCon> but your comment causes WG members to doubt that the KIF produced by n-triples2kif.pl is anything less than 100% agreed as to its meaning in the math, logic, and CS communities. <danbri> FOL is a beatiful piece of machinery, and has power precisely because it is diconnected from the grubby real world. The different understandings are not w.r.t. to the internal workings of FOL, but about how they map into the world. <DanCon> yes, and those mappings are irrelevant to the issue of rdfms-anon-resources <danbri> Not if we want RDF/XML documents to mean something in the T-and-S social/legal sense, for it to be clear what claims someone is making about the world when they sign a piece of RDF data. <DanCon> fuck fuck fuck! I just can't get you to stop muddling everything together. yes, anon-resources *is* orthogonal to all those t-and-s issues. <DanCon> my 2 hour estimate was wrong. <DanCon> model theory is one thing. standard interpretations (bindings to the real work) is another. <DanCon> I apologize for my lack of patience. <DanCon> This is a non-trivial subject. * danbri stops sitting on his hands <DanCon> It's just that I *know* you understand the technical difficulties. <DanCon> rather: I know you understand the technical solution. <danbri> Yes, it's non trivial. And I do find it easier to see the connections between the problem parts than the solution. <DanCon> I just can't get you to separate the solution to this issue from all the other issues in your head. <danbri> So, are we both happy reading anonymous resources as 'there exists'? <DanCon> I am happy reading it that way (in the technical sense of 'there exists' as in FOL/KIF) <DanCon> I have expressed my happines reading it that way in running code: n-triples2kif.pl <danbri> And are you happy when I go on to say that this consensus doesn't alone entirely fix the social/legal meaning of RDF/XML fragments that use the anonymous resource construct? <DanCon> absolutely. A solution to anon-resources does not solve all the world's problems regarding social binding of RDF documents. <danbri> Ok, I'm getting a sense for how we manage to talk past one another. I've been hearing you as saying 'anons = FOL there exists, end of story'. <danbri> I should rephrase my position to sound less FUDish: <danbri> I should say: "we can reduce the 'what do I mean when I use the RDF anonymous resources construct' problem to the better understood 'what do I mean when I use the FOL existential quantifier'" <DanCon> QUITE! <DanCon> BINGO! <danbri> And you'll allow my mutterings about Quine and unicorns to live in that 2nd problem space, which was all I wanted :) <DanCon> any objections? hearing non, so ordered. yes. agreed. <danbri> how'd you feel about copying this log (swearin' and all) into <danbri> #rdfig for archival. <DanCon> hard question. <DanCon> er... ok, I'm OK to have it copied to public space <danbri> Ok, copying from 'how much longer' to 'I'm OK'. <DanCon> I was going to suggest starting with "so are we both happy..." <DanCon> but very well.
