Data Description and Requirements

This document summarizes the producer-level and associated third-party data collected by the ESMC portal. The objectives of this document are to provide the reader with the following:

  1. an understanding of the data being collected;
  2. an overview of the database structures employed to collect and manage the data; and
  3. an introduction on how to utilize and read the detailed data specifications given as part of the OpenAPI specification at, which is the definitive source of record for the data and its interpretation.

Please note that in addition to collecting producer data, the ESMC portal imports data from other platforms, integrates third-party data, generates data, and exports data. An overview of this data is provided below.

Data Intake

Data is collected by the ESMC portal through the following, non-exclusive methods.

  1. Direct data entry into the portal (
  2. Import through the ESMC API (see for details).
  3. Use-case specific manual or scripted inputs directly into the database.
  4. (Future) Producer-initiated import from another platform.

In addition to collecting the data from various sources, the data requested and required by ESMC varies based on the asset or credit for which the producer (or project) is seeking. The five assets and credits presently supported by the portal are as follows:

  1. Scope 1 Green House Gas (GHG) Credit
  2. Scope 1 Water Quality (WQL) Credit
  3. Scope 3 GHG Asset
  4. Scope 3 WQL Asset
  5. Scope 3 Water Quantity (WQN) Asset

The data requirements for each credit/asset are given below.

Data Structure

The ESMC database is structured in an hierarchical manner as illustrated in the following image. In general terms, every project has a list of producers, each producer has a set of fields (which can change on an annual basis), each field has crops and herds which change over time, and each crop and herd are managed with a program.

As noted above, the master data specification for each of the above components is maintained in an OpenAPI format at However, for the reader’s convenient, the following is provided as an introduction to the OpenAPI specification and as a quick data overview summary. For detailed specification, direct links to the relevant OpenAPI specification are provided for the readers convenience.

Since the OpenAPI specification may be new to the reader, the following graphic has been created using the Drainage Component to explain how to read the documentation. As shown, the Drainage Component collect 4 data inputs: percentOfField, tileDepth, treatmentTypes, and treatmentPercentOfFields. Also note that these parameters are required for all credits and assets except for Scope 3 Water Quantity assets as stated in the top table.

Furthermore, note that a description for each parameter (unless the description is self-explanatory, e.g., percentOfField), the valid range of the input parameter, the units of the parameter (when applicable), and the allowable parameter options are provided.

A detailed description of each data element collected on import or provided on export is provided as shown in the following figure. Simply click on a component in the left toolbar to see the detailed data specification for that component. Also, please note that while an example JSON file is given for each component in the right panel (not shown), the JSON format is provided as an aid to the developers and is not needed to understand the parameters.
