It seems to me that the data in an rdbms is often structured in ways that are designed to be efficient for the rdbms to manage rather than in ways that make sense externally. Levels of normalisation are the main thing I'm thinking of. LD is most widely useful at 5th Normal Form, but then there are tradeoffs that usually lead to an rdbms schema being more like 3NF. Isn't the effort in publishing LD the same effort that one expends getting the data from the rdbms into HTML today, but that the data needs to be in RDF? When doing that don't tradeoffs in the schema have to be reconciled through queries that join from several tables or that select distinct entries in particular columns? Isn't that what Drupal and Ruby-n-Rails and so on are optimised to do? I agree with the notion of lowering the barrier and Virtuoso's mapping stuff is really interesting, but is the cost really that high right now? Isn't it just the same as writing some dynamic web pages? rob Rob Styles tel: +44 (0)870 400 5000 fax: +44 (0)870 400 5001 mobile: +44 (0)7971 475 257 msn: mmmmmrob@yahoo.com irc: irc.freenode.net/mmmmmrob,isnick web: http://www.talis.com/ blog: http://www.dynamicorange.com/blog/ blog: http://blogs.talis.com/panlibus/ blog: http://blogs.talis.com/nodalities/ blog: http://blogs.talis.com/n2/ Please consider the environment before printing this email.
