RE: Issues with XML and Semantic Web ?
Kendall, We discussed it before because I had said (a bit facetiously) that the current Semantic Web is mostly FOAF files, tools, and talk. I certainly wouldn't deny that FOAF files are part of the Semantic Web; without them, there'd be little left! As I've mentioned on the rdf-interest list, I still haven't heard a use case that demonstrates what value RSS 1.0 files of transient data can play in a semantic web. If it was current practice to archive them (like monkeyfist does) and I was reading an article by someone and wanted to see more by that person, semantic web technology crawling RSS 1.0 archives would make it easy to turn up more articles by that person. Maybe not everything he ever wrote, because in some bylines he may use his middle initial or called himself "James" instead of "Jim", but I would have found something. It's not that I'm against transient data having any role period. Movie timetables are transient data, so if someone made those available as RDF files (haven't found anyone who does yet), I could obviously see why those would be useful. I'm just wondering how people can apply semantic web technology to take advantage of transient RSS 1.0 files to do things that they can't do with RSS .9, 2.0, etc. files. In other words, what makes them part of the semantic web? The mere fact that they're in RDF? The SemWeb life sciences conference is a great example of how a specific domain, especially one currently suffering from data overload, is fertile ground for proving the value of semantic web technology, and publicly available data is appearing (http://www.rdfdata.org/data.html#bio). I was just telling a biomedical research professor about it over the weekend, and he was anxious to hear more.

I don't know why you discount that data as non-transient. That people don't archive all of their RSS 1.0 events seems a matter of a best practice. It doesn't change the fact that there are *lots* of RSS 1.0 (which are RDF) resources on the Web. (And there are good social reasons for why people might not want to maintain all their FOAF versions.) It seems to me that we're maybe in the "intranet" phase of the Semantic Web, that is, lots of non-public RDF inside enterprise and institutional walls, while the amount of RDF on the public Web continues to grow (even if not exponentially). Lots of folks using RDF and OWL in the life sciences world, or so I learned at the W3C's workshop about SemWeb in LifeSci in Boston a few weeks ago, and the great majority of that isn't on the public Web. My two cents, anyway. :> Kendall Clark Managing Editor, XML.com -- Sometimes it's appropriate, even patriotic, to be ashamed of your country. -- James Howard Kunstler
