This is a good point. (01)
Someone who wants semantic querying and storage capabilities can build a
semantic front end top a traditional RDB, or can have a go at doing it
natively (which is to some extent, what a object-oriented data store
does).
There may be performance tradeoffs. (02)
Until/Unless someone builds a semantic data store with similar
performance as rdbs, they are likely to be the main backend technology
for semantic reasoning/storage systems. (03)
A hard-core rdb person might argue: I don't want object-oriented dbs, or
triple stores, or any of that semantic crap, all I need is a rdb.
However this misses the point, there are advantages of having a semantic
capability; there may also be performance tradeoffs. I think that
Oracle's RDF store capability is much slower than their main product. (04)

Mathew,
Since the large ontology-based applications that will be useful for
major problems are likely to use relational databases (or their
equivalent) as their back-end, what is the problem with saying that the
capabilities of such systems are more advanced than the capabilities of
database systems alone? They are indeed not "competing" but they are
also not "complementary"; the larger ontology-based systems will build
on and extend the database systems. (07)

Dear Ray, (011)
The first "conclusion in brief" is: (012)
"(1) We agree that the technology of modeling and representing knowledge
has developed to the point where it is feasible to create
knowledge-based reasoning systems with information analysis and
exploitation capabilities significantly more advanced than traditional
systems based on relational databases and object-oriented programming
without semantic interpretation." (013)
Well I don't agree. (014)
Ontology can help improve the design of systems using traditional
technology, and I can see Knowledge Based Applications adding
significant value to those traditionally developed systems. I can also
see some genuinely "the web as a database" type applications.
However, I think it is inappropriate to compare in this way traditional
systems (that are largely transaction processing
based) and Knowledge Based Systems. They are complementary not competing
technologies. (015)
