[snip] Just so -- personally, I've had no need to use most of the stuff either (it's a classic 80/20 thing), and I've written ad-hoc RDF libraries that work just fine for my customers' real-world requirements, including one for WavePhore that's happily processing streaming RDF data records for over 2,000 newswire stories (probably more than that by now) every day at dozens of customer sites. Certainly, we can define formats that happen to be RDF-compatible (like XMLNews-Meta ), but to create a general-purpose RDF processing software that will make it worthwhile to standardize on RDF, we have to implement all of the bogosity in the spec. -- hence my complaint. I have no problem writing an RDF/Foo engine for customer A, and RDF/Bar engine for customer B, and an RDF/Hack engine for customer C -- heck, I'm billing for them -- but they should all be able to share the same RDF engine(s); otherwise, why not just define the Foo, Bar, and Hack formats directly, without worrying about RDF compatibility? > Perhaps the key is that I'm not trying to construct a comprehensive > object model - I'm just trying to use metadata to look things up. > I find RDF just fine for that. Exactly, but you're free to implement only the subset that you need for your project -- as you know, people do exactly the same with XML (though with so many good parsers now, most just use the DOM or SAX).
