The Avanti Nova semantic mapping system finally has a web based interface.  You can try out the demo on the web site:  http://www.avantilibrarysystems.com .  It implements a simple catalog of a small collection of title records plus other resources from elsewhere.  It is an example of a different approach to a library catalog.  None of the implementation is hardcoded into Nova itself. 

This is a reference implementation.  Not necessarily a production application, but one that can be extended into many different directions.  The web part is a set of php modules that talk to the Nova server via its own application network protocol.  Everything is clickable.  Give it a try!  And let me know what you think.
