You may be interested in the following ....

It's called Internet Business Logic.  The commercial-sounding name 
notwithstanding, there is a theory foundation (refereed papers) and an 
implemented system (free for academic use).

It's live, online at www.reengineeringllc.com , where you will also find 
some presentations and pointers to the papers.

In particular, the "Semantic Web Presentation" argues that (lightweight) 
English language processing. combined with heavyweight inferencing, is 
essential if anyone is to trust the SW with real world tasks.

The author- and user-interface for the system is simply a browser.  When 
needed, the system automatically generates and runs SQL queries and 
transactions over networked RDBMSs.  However, the language is more powerful 
than SQL -- e.g. it has safe recursion.

There are a number of ontology examples that you can view and run. 
(RDFQueryLangComparison1 might be a good one to start with.)  You can also 
write and run your own examples.

HTH.  Thanks in advance for comments.   -- Adrian
