Background

To ensure IDS schema consistency across multiple IDSs, use the supplied schema templates provided below.

Commonly Used Definitions

Add the schema template to the definitions section of your IDS, and reference the property in other parts of your IDS using "$ref": "#/definitions/<property>"

  "nullable_string": {
    "type": [
      "string",
      "null"

Nullable Number

{
  "nullable_number": {
    "type": [
      "number",
      "null"
    ]
  }

          "$ref": "#/definitions/nullable_string"
        },
        "version": {
          "$ref": "#/definitions/nullable_string"
        }
      }
    }
  }
}

Software

GSFs

Systems

GSF. Not required. Extendable. You need to use the schema below as the base template. You can't remove fields from the base template and you can't reduce the required list.

GSFs you can choose to use in systems are in the schema below. If you choose to use firmware or software, please use the schemas defined in the definitions section.

{
        "id": {
          "$ref": "#/definitions/nullable_string"
        },
        "name": {

        }
}

Users

GSF. Not required. Extendable.

The exact schema needs to be copied to every schema.json even if the raw data doesn’t have user info.

You should determine if certain fields are required based on the instrument you are working with and put into required field.

"users": {
  "type": "array",
  "items": {
    "type": "object",
    "required": [],
    "additionalProperties": false,
    "properties": {

        "description": "User ID"
      },
      "name": {
        "$ref": "#/definitions/nullable_string",
        "description": "Username"
      },
      "type": {
        "$ref": "#/definitions/nullable_string",
        "description": "User type or role"
      }
    }
  }
}

Samples

GSF. Not required. Non-Extendable.

The exact schema needs to be copied to every schema.json even if the raw data doesn’t have sample info.

You should determine if certain fields are required based on the instrument you are working with and put into required field.
