Do some citeseer searches for NIAM, nijssen and halpin. They set the reference point for conceptual modelling about 20 years ago.
Since that time, I have seen nothing I would consider a groundshaking improvement; although, Jan or Vadim might have a better idea if something significantly changed the state of the art in recent years.
If you want anyone to take you seriously, you will first have to demonstrate some knowledge of the prior art. Received on Thu Apr 13 2006 - 22:57:58 CEST
