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.
