|
| This document explains the meaning of each key in the `dataset.json` file (as of v1.0.0). |
|
|

|
|
| ## 1. Root Object |
|
|
| The JSON file is a single object with three main keys: |
|
|
| * `"metadata"`: (Object) General information about the dataset. |
| * `"diseases"`: (Array) A list of pathological diseases (caused by fungi, algae, etc.). |
| * `"pests"`: (Array) A list of harmful pests (insects, mites, nematodes). |
|
|
| --- |
|
|
| ## 2. Metadata Fields |
|
|
| Contains descriptive information about the dataset itself. |
|
|
| * `"name"`: The full name of the dataset. |
| * `"version"`: The current version (following SemVer MAJOR.MINOR.PATCH). |
| * `"description"`: A brief description of the dataset's purpose. |
| * `"creator"`: (Object) Information about the author. |
| * `"name"`, `"affiliation"`, `"email"`, `"orcid"` |
| * `"created_date"`: The date the project was initiated. |
| * `"last_updated"`: The date the JSON file was last modified. |
| * `"license"`: The license code (e.g., "CC BY 4.0"). |
| * `"geographical_coverage"`: The geographical region this data applies to (e.g., "Mekong Delta", "Tây Nguyên"). |
| * `"number_of_diseases"`: Total count of items in the `diseases` array. |
| * `"number_of_pests"`: Total count of items in the `pests` array. |
| * `"data_source"`: A general description of the data sources. |
| * `"repository_url"`: The URL to this GitHub repository. |

|
| ## 3. Disease and Pest Fields |
|
|
| Both `diseases` and `pests` are arrays of objects. Each object describes one specific problem. |
|
|
| ### 3.1. General Information |
|
|
| * `"disease_id"` (or `"pest_id"`): A unique identifier (e.g., "SR001", "P001"). |
| * `"disease_name"` (or `"pest_name"`): The most common name (e.g., "Stem Canker"). |
| * `"scientific_name"`: The scientific name of the pathogen or pest (e.g., "Phytophthora sp."). |
