Legislation parameters

Definition

The legislation parameters are stored in a file named param.xml.

It contains parameters which can be simple parameters (<CODE> tags) or scales (<BAREME> tags).

It is ordered as a tree defined by <NODE> tags.

Here is a simple parameter sample:

<CODE code="taux_plein" description="taux plein de la CSG déductible" format="percent">
  <VALUE deb="2005-01-01" fin="2014-12-31" valeur=".042" />
  <VALUE deb="1998-01-01" fin="2004-12-31" valeur=".038" />
  <VALUE deb="1997-01-01" fin="1997-12-31" valeur=".01" />
</CODE>

The param.xml file itself has a start and an end date.

Query

Formulas retrieve parameters using the simulation.legislation_at(instant) method.

• if instant >= root_end_date
  • if value_end_date >= root_end_date return last known value
  • else return 0
• else if instant <= root_start_date
  • if value_start_date <= root_start_date return first known value
  • else return 0
• else return value

Usage example (see in context):

def function(self, simulation, period):
    period = period.start.offset('first-of', 'year').period('year')
    f6eu = simulation.calculate('f6eu', period)
    f6ev = simulation.calculate('f6ev', period)
    acc75a = simulation.legislation_at(period.start).ir.charges_deductibles.acc75a
    amax = acc75a.max * max_(1, f6ev)
    return period, min_(f6eu, amax)
