If the use case here is to reuse some common assets (for example, rules, 
decision tables, fact models, working sets etc) from packages, the 
Global area will be the thing you are looking for. You create your 
common assets in the Global area (think the global area as a special 
package, that's all). Then in your individual packages, you create an 
asset which is linked to the asset from global area (choose "import from 
Global area").

Please note, there was bug report against Global area in Drools 5.1: 
https://issues.jboss.org/browse/GUVNOR-1124. It has been fixed on trunk 
and will be available in Drools 5.2_M1.

Hope this helps,
Jervis
