[rules-users] How do you use packages in Guvnor?

[Michael Anstis]

Packages in Guvnor (and Drools for that matter) are just containers to
collate related things.

A package compiled within Guvnor will contain all assets within the
package, and only that package: no inheritance etc.

The fact that a package name is its parent's name plus some suffix (e.g.
parent.child) has no significance to Guvnor (or Drools).

How you want to use packages to bundle your rules is up to you really. You
might prefer to split as you have based on vehicle type, however you might
equally find one package holding rules that change infrequently (e.g. rules
relating to taxation etc) and another holding frequently changing rules
(e.g. weather conditions). You could then build and deploy the frequently
changing rules without fear of affecting the infrequently changing rules.

With kind regards,

Mike
