Flow
An input or output of an entity to or from an instance of an Activity or a directional exchange of an entity between two instances of Activity. This class contains the quantity of the entity (Flow Object) that is consumed as input or produced as output of an Activity.
Activity
Activity is the act of making or doing something which is defined both spatially and temporally. This is one of the identifying dimensions of a datapoint. This class defines multiple properties on the type and direction of flows. ‘Process’ is a commonly used synonym in other LCA databases.
Balanceable Property Type
Contains the labels of BalanceableProperty such as dry mass, wet mass, elemental mass, person-time, monetary value.
Balanceable Property
A quantity for which the sum for all input flows must equal the sum for all output flows. A quantity that follows a conservation law. Balanceable properties are particularly relevant for validating the completeness and consistency of an Activity description or a database of such activities.
has balanceable property
Specifies the Measure of a Flow when this Measure is a BalanceableProperty, i.e. when it follows a conservation law.
property type
Specifies the dimension (Quantity) of a Measure that is classified as a BalanceableProperty.
proportional to
Specifies the reference unit that the amount of a BalanceableProperty of a Flow is proportional to.
Activity Type
The type of an activity, e.g, stock accumulation, steel production, etc. This class includes the labels of activities. Includes both human activities and environmental mechanisms.
references flow object
Specifies a FlowObject that functions as the ReferenceUnit for a BalanceableProperty measure.
Flow Object
This class includes the labels of entities that are produced or consumed by an activity or added to or removed from a stock accumulation.
temporal extent
Specifies the temporal extent for an activity.
activity type
Specifies the label of an Activity.
determining flow
Specifies a specific flow object produced or consumed by an activity for which a change in demand or supply will affect the activity level (such as its production volume or extent).
Agent
An entity (person or thing) that performs an activity, usually it has a specific location.
input of
Specifies the Activity that a Flow is an input to.
Reference Unit
The measure to which the numeric value representing the measure of a Flow is expressed 'in proportion to'. In LCA, the term ‘Functional Unit’ is defined as a common ReferenceUnit for all activities in an LCA study.
located at
Specifies the location of an Activity or Agent
output of
Specifies the Activity that a Flow is an output of.
performs
Specifies the Agent who performs an activity.
object type
Specifies the Flow object consumed or produced.
