[drools-research] Re: [rules-users] EulerGUI released - IDE for semantic Web with Drools engine and Drools export

[Andrew Waterman]

Hi Jean-Marc,

Are you using the template functionality in Drools 5.0 for OWL?  We  
use Drools for expressing models/games down here and I have been  
looking for an approach that would provide a more generic way of  
defining data-models and rules that act on them.

Also, I wonder if you've looked at Miles Parker's MetaScape ABM  
modeling plugin for Eclipse.  It's  a different area, but he has put  
together a very nice visual way of working with both models (data) and  
actions (rules).

I will download your project and look a bit deeper.

Many thanks for the posting and the links; wonderful discussion.

best wishes,

Andrew
