From: "Jonathan Rochkind" HTML works out pretty well. If our biggest failures were 'failures' like HTML, we'd be doing pretty well. HTML is a wonderful standard. And I don't mean to take the discussion off-course. My point was simply that because early browsers did not insist on clean html

It can be a chicken-egg thing too. Maybe more users would be doing more sophisticated searches if they actually _worked_. Plus I know that I could write systems to use federated search to embed certain functionality in certain places, if more sophisticated searches worked more reliably. Wal

I'm not sure it's a _big_ mess, though, at least for metasearching. I was just looking at our metasearch logs this morning, so did a quick count: 93% of the searches were keyword searches. Not a lot of exactness required there. It's mostly in the 7% who are doing more specific searches (author

From: "Mike Taylor" The irony is that Z39.50 actually make _much_ more effort to specify semantics than most other standards -- and yet still finds itself in the situation where many implementations do not respond correctly to the BIB-1 attribute 6=3 (completeness=complete field) which is how Er
