The RulesTool implements portal object
transformation policies.
An object transformation template is defined by
a domain and a transformation pattent:
The domain is defined as:
- the meta_type it applies to
- the portal_type it applies to
- the conditions of application (category membership, value range,
security, function, etc.)
The transformation template is defined as:
- a tree of portal_types starting on the object itself
- default values for each node of the tree, incl. the root itself
When a transformation is triggered, it will check the existence of
each node and eventually update values
Transformations are very similar to XSLT in the XML world.
Examples of applications:
- generate accounting movements from a stock movement
- generate a birthday event from a person
ERP5 main application : generate submovements from movements
according to templates. Allows to parametrize modules
such as payroll.
Try to mimic: XSL semantics
