• created_at (DateTimeField) – Created at

• updated_at (DateTimeField) – Updated at

• weight (FloatField) – Weight

• ordering (IntegerField) – Volgorde

Relationship fields:

Parameters:

• assessment_strategy (ForeignKey to AssessmentStrategy) – Assessment strategy (related name: related_impact_indicators)

• impact_indicator (ForeignKey to ImpactIndicator) – Impact indicator (related name: assessmentstrategyimpactindicator)

Reverse relationships:

Parameters:

class assessment_strategies.models.DataSource(*args, **kwargs)

The environmental impacts on Environmental Data are sourced from some data set. Not all data sources are suitable for every Assessment Strategy. To keep track of the data sources, every Environmental Data can be coupled to a DataSource.

Currently the DataSources are:

• Ecoinvent 3.6, suitable for AssessmentStrategies A1 and A2

• Ecoinvent 3.9, suitable for AssessmentStrategy A2

Parameters:

• id (UUIDField) – Primary key: Id

• created_at (DateTimeField) – Created at

• updated_at (DateTimeField) – Updated at

• code (CharField) – Code

Relationship fields:

Parameters:

assessment_strategies (ManyToManyField to AssessmentStrategy) – Assessment strategies (related name: datasource)

Reverse relationships:

Parameters:

environmental_data (Reverse ForeignKey from EnvironmentalData) – All environmental data of this databron (related name of data_source)
