Flow
subclass of: Measure
subclass of: ConceptScheme
comment: 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.
type: Class

Activity
subclass of: ConceptScheme
comment: 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.
type: Class

Balanceable Property Type
subclass of: Quantity
subclass of: ConceptScheme
comment: Contains the labels of BalanceableProperty such as dry mass, wet mass, elemental mass, person-time, monetary value.
type: Class

Balanceable Property
subclass of: Measure
subclass of: ConceptScheme
comment: 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.
type: Class

has balanceable property
range: Balanceable Property
domain: Flow
comment: Specifies the Measure of a Flow when this Measure is a BalanceableProperty, i.e. when it follows a conservation law.
type: ObjectProperty
type: FunctionalProperty

property type
range: Balanceable Property Type
domain: Balanceable Property
comment: Specifies the dimension (Quantity) of a Measure that is classified as a BalanceableProperty.
type: ObjectProperty
type: FunctionalProperty

proportional to
range: Reference Unit
domain: Balanceable Property
comment: Specifies the reference unit that the amount of a BalanceableProperty of a Flow is proportional to.
type: ObjectProperty
type: FunctionalProperty

Activity Type
subclass of: ConceptScheme
comment: 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.
type: Class

references flow object
range: Flow Object
domain: Reference Unit
comment: Specifies a FlowObject that functions as the ReferenceUnit for a BalanceableProperty measure.
type: ObjectProperty
type: FunctionalProperty

Flow Object
subclass of: ConceptScheme
comment: This class includes the labels of entities that are produced or consumed by an activity or added to or removed from a stock accumulation.
type: Class

temporal extent
range: ProperInterval
domain: Activity
comment: Specifies the temporal extent for an activity.
type: ObjectProperty
type: FunctionalProperty

activity type
sub property of: type
range: Activity Type
domain: Activity
comment: Specifies the label of an Activity.
type: ObjectProperty

determining flow
range: Flow
domain: Activity
comment: 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).
type: ObjectProperty
type: FunctionalProperty

Agent
subclass of: ConceptScheme
comment: An entity (person or thing) that performs an activity, usually it has a specific location.
type: Class

input of
range: Activity
domain: Flow
comment: Specifies the Activity that a Flow is an input to.
type: ObjectProperty
type: FunctionalProperty

Reference Unit
subclass of: Measure
subclass of: ConceptScheme
comment: 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.
type: Class

located at
range: location
domain:
  union of: Activity
  union of: Agent
  type: Class
comment: Specifies the location of an Activity or Agent
type: ObjectProperty
type: FunctionalProperty

output of
range: Activity
domain: Flow
comment: Specifies the Activity that a Flow is an output of.
type: ObjectProperty
type: FunctionalProperty

performs
range: Activity
domain: Agent
comment: Specifies the Agent who performs an activity.
type: ObjectProperty

object type
sub property of: type
range: Flow Object
domain: Flow
comment: Specifies the Flow object consumed or produced.
type: ObjectProperty
type: FunctionalProperty
