Schema

Indicator

Type: Blank Node

View examples

An emission, resource use, or characterised environmental impact indicator. Each Indicator must be unique, and the fields which determine uniqueness are defined in the emissionsResourceUse, impacts, and endpoints fields of the Impact Assessment.

Field Type Required Definition
term Term Yes

A reference to the Term describing the emission e.g., CH4, to air, crop residue burning; the resource use e.g., Freshwater withdrawals, during Cycle; or the characterised environmental impact indicator e.g., Terrestrial ecotoxicity potential (1,4-DCBeq).

value number|null Yes

The quantity. If an average, it should always be the mean.
distribution array[number] No

An array of random draws from the posterior distribution of the Indicator.
sd number No

The standard deviation of value.
min number No

The minimum of value.
max number No

The maximum of value.
statsDefinition string No

What the descriptive statistics (sd, min, max, and value) are calculated across, or whether they are simulated or the output of a model. spatial refers to descriptive statistics calculated across spatial units (e.g., pixels) within a region or country. time refers to descriptive statistics calculated across units of time (e.g., hours).

Possible values are: sites, cycles, impactAssessments, replications, other observations, time, spatial, regions, simulated, modelled
observations integer No

The number of observations the descriptive statistics are calculated over.
methodModel Term No

A reference to the Term describing the method or model for calculating these data. This is a required field for characterised indicators.

methodModelDescription string No

A free text field, describing the method or model used for calculating these data.
inputs List[Term] No

For emissions or resource uses related to an Input, the Term describing the Input.

inputs cannot be duplicated. The following fields determine whether a List[Term] is unique: @id

operation Term No

For emissions or resource uses created by an operation, the Term describing the operation.

transformation Term No

For emissions or resource uses created during a Transformation, the Term describing the Transformation.
