Schema

A description of the Cycle, including information that cannot be captured with other fields.

A description of the treatment administered by researchers to the experimental unit. E.g., a Site is divided into four and each part is 'treated' with a different fertiliser type to see which produces the most maize (Easton & McColl (1997)). Use the numberOfReplications field to specify the number of replicates for each treatment.

Whether this treatment is representative of typical commercial practice. Required if treatment is specified.

The end date or year of the Cycle in ISO 8601 format (YYYY-MM-DD, YYYY-MM, or YYYY). If startDate is specified to month or day precision, endDate should be too. For crops, endDate is always the harvest date. For continually harvested crops, it should be the end of the year.

The start date of the Cycle in ISO 8601 format (YYYY-MM-DD, YYYY-MM, or YYYY). Use the startDateDefinition field to define what this represents. For consistency with FAOSTAT, this should ideally be the date of harvest of the previous crop (a fallow period of greater than a year but less than five years is counted as a crop). However other start dates can be specified, such as the sowing date or soil preparation date. For continually harvested crops it should be the start of the year.

A definition of what the start date is. This is a required field if startDate is provided.

Possible values are: harvest of previous crop, sowing date, transplanting date, soil preparation date, orchard or vineyard establishment date, first bearing year, stocking date, start of year

The duration of the Cycle in days. Calculated from startDate and endDate if provided.

Defaults to: 365

A reference to the Site describing the primary location where this Cycle occurred.

If the Cycle occurred on multiple Sites, a list of the other Sites.

The duration on the primary site in days. For a single Site, this is equal to cycleDuration.

If a Cycle occurs on multiple Sites, a corresponding array to otherSites representing the number of days on each Site.

The units that the inputs, emissions, products, and transformations are expressed 'per'. Can either be: 1 ha (one hectare) or relative (meaning that the quantities of Inputs and Emissions correspond to the quantities of Products). If the primary product is a crop, the functional unit can only be 1 ha.

Possible values are: 1 ha, relative

Further information on the functional unit (e.g., 'one batch').

If data on multiple Cycles are aggregated and represented as a single Cycle, the number of Cycles. For example, Cycles occurred on the same site in multiple growing seasons might be represented as a single Cycle with standard deviations across Cycles.

In experimental studies, the number of replicates for the treatment.

In surveys, the sample weight for this Cycle relative to all other Cycles included in the Source.

For crops, the area harvested in hectares. Area harvested is the same as area under cultivation if the entire cultivated area is harvested, but less if crops fail or are not harvested for economic or other reasons.

The default classification of the method used to acquire or estimate all Input, Product, Practice, and Transport data in the Cycle. It can be overridden by specifying a methodClassification for each Input, Product, Practice, or Transport stage.

• physical measurement means the amount is quantified using weighing, volume measurement, metering, chemical methods, or other physical approaches.
• verified survey data means the data are initially collected through surveys; all or a subset of the data are verified using physical methods; and erroneous survey data are discarded or corrected.
• non-verified survey data means the data are collected through surveys that have not been subjected to verification.
• modelled means a previously calibrated model is used to estimate this data point from other data points describing this Cycle.
• estimated with assumptions means a documented assumption is used to estimate this data point from other data points describing this Cycle.
• consistent external sources means the data are taken from external datasets referring to different producers/enterprises:
  • Using the same technology (defined as the same System or the same key Practices as those specified in the Cycle);
  • At the same date (defined as occurring within the startDate and endDate of the Cycle); and
  • In the same region or country.
  Modelling or assumptions may have also been used to transform these data.
• inconsistent external sources means the data are taken from external datasets referring to different producers/enterprises:
  • Using a different technology (defined as a different System or using different key Practices to those specified in the Cycle);
  • At a different date (defined as occurring within the startDate and endDate of the Cycle); or
  • In a different region or country.
  Modelling or assumptions may have also been used to transform these data.
• expert opinion means the data have been estimated by experts in the field.
• unsourced assumption means the data do not have a clear source and/or are based on assumptions only.

Possible values are: physical measurement, verified survey data, non-verified survey data, modelled, estimated with assumptions, consistent external sources, inconsistent external sources, expert opinion, unsourced assumption

A justification of the defaultMethodClassification used. If the data were estimated with assumptions this field should also describe the assumptions.

The default Source for all data in the Cycle which can be overridden by specifying a source for each Input, Emission, Product, or Practice. Required for public uploads (i.e., where dataPrivate is false).

A specification of how complete the inputs and products data are. If an area of activity data is marked as complete, then the associated Inputs and Products represent a complete description of the Cycle.

The Practices used.

The types of Animal present.

The Inputs used.

The Products created.

The Transformations applied to products generated from this Cycle.

The Emissions created.

If these data are private. Private means that Hestia administrators can access these data and you can grant access to other platform users, but these data will not be made available to any other users of the platform or distributed to third parties.

Defaults to: False

An automatically generated name for the Cycle composed of: primary product name, "-", site.region "," site.country, "-", endDate, "-", treatment, and/or description.

The identifier for these data in the source database (e.g., if the data were converted from openLCA or ecoinvent, the id field from that database).

The version of the schema when these data were created.

A list of fields that have been added to the original dataset.

A list of versions of the model used to add these fields.

A list of fields that have been updated on the original dataset.

A list of versions of the model used to update these fields.

If this Cycle has been 'aggregated' using data from multiple Cycles.

A version of the aggregation engine corresponding to this Cycle.

A data quality score for aggregated data. Multiple points can be awarded for: no Emissions are missing from the system boundary; the aggregation is based on data from over fifty Cycles; the difference between FAOSTAT yield and the aggregated yield for the primary product is less than ±20% (crop only); countries representing at least 75% of global production are included (Global aggregation only); and data Completeness is true for all areas.

The maximum value for the aggregated quality score.

Cycles used to aggregated this Cycle.

Date created on Hestia in ISO 8601 format (YYYY-MM-DD).

Last update date on Hestia in ISO 8601 format (YYYY-MM-DD).
