No, no; why is there some automatic notion that if our data is compelling enough, the tools we need will be created? I'm not questioning the need nor want for compelling applications, only the assumption that once we get to stage 1, stage 2 will automatically follow. We're all looking for that killer application, but perhaps we're mistaking the killer app for techies for the killer app for the real-world? > Google do seem to have noticed that the hocus pocus (whether or not > they call it RDF) has its place. I was more pointing to RDF being the culprit. When Google wants to buy a few million bibliographic records, do they embrace MARC, MARC XML, MODS, MADS, or RDF versions of the same? Nope, they create some simple XML to represent the very basics they feel they need, and use that. Same with most of the RDF data; silo mentality of the value of datasets are incredibly hard to evaluate in the Linked Data world; you have to take on good faith that the quality within is good enough for whatever killer app you're writing. And quite often you only discover lacks and poor data quality once you've gone down the path of development for a while, never a pleasant journey. Are you expecting killer apps based on data with faith-based quality control, and big hurdles for evaluation of value? >> The Semantic Web was crafted on the potential of fixing problems a tad >> bit better than what we already had that already fixed the problems, > > I disagree somewhat - would take me a while to find the exact quote, > but Tim has stated words to the effect that the semweb can make > problems previously considered impossible become a bit obvious. (A > point with which I agree strongly). You are of course right, but all of that is theory. In practise we are rehashing old problems in new ways. I guess what you're longing for is the tipping point of going from solving those problems to solving new ones. >> so basically fixing a non-existent problem.

If this stuff was easy, we probably would see tons of it. But we don't, and I suspect that the tooling sucks in a sense that it is hard for people in the real-world to wrap their heads around them. SGML was brilliant, but hard to fully grasp. And we know who's your generic markup daddy. > "informolasses" goes straight into my vocab, thanks.

I have tons of similar problems. Even online tools I know how to use and hack and exploit can sometimes draw up a blank. Like finding a Guinea Pig breeder on the south coast of Sydney when you need one; 1) there might not actually be any, or 2) there is no information about them on the web to be crawled. The problem is not that they haven't published their details in glorious Turtle. But is this stuff really the same problem as the Linked Data and lack of killer apps, though? >> All this data and their weak relationships are great to play with, >> though, and it might shape things to come, but to get the masses to do >> something interesting with it you need to convince them that >> "ontology" is even a word that deserves a place in our daily >> languages.

I can't kick you in the shin based on faulty reasoning or understanding of what I admittedly poorly wrote. :) The point was that Linked Data uses ontologies because, like you say, they're shared vocabularies. Not the most complex vocabularies, of course, but vocabularies or ontologies nevertheless. I doubt interchanging "vocabulary" with "ontology" has the slightest effect on people's understanding of how these things fit together, and *especially* not the potential therein. What I don't understand is that people have no problem understanding names of elements in an XML schema, and link that and its data content to records or fields in a database (which is a fuzzy undertaking when you get right down to it), but have huge problems taking a triplet or two and doing the same. There seem to be some cognitive mismatch happening when you introduce the tiniest third directional signifier. It's puzzling. Is the human brain too capable of doing one-to-one mapping that it fails our attempts at many-to-any? >> In other words, the technology, its promises and potential means >> *nothing* when a small paradigm shift is needed. > > Despite my negative comments recently, I do think that paradigm shift > is happening.
