Of course... but even though. IMO, not easy enough! I'm taking the
position as owner of one of the million web applications out there,
powered by a rdbms, and now hearing about the LD thing going on. If
I want to be part of it... I would have to invest a lot of time and
effort with existing tools such as d2r sever, etc...
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?
