OperationType
| OperationTypeEnum
| 1 | Type of Prescription: Missing. Crop Protection, Tillage, etc If we're needing to make these as standalone as possible, we will likely need to add a DDI somewhere.. 201509 |
| FieldId | Integer | 1 | |
| CropZoneId | Integer | 0..1 | |
| ProductIdsRxLookupIds | Integer | 0..* | Prescriptions can have multiple Products. Important for a variety of needs. 20150925: Listing them here is somewhat redundant, albeit useful. |

RxLookup
| Attribute | Type | Multiplicity | Description |
|---|---|---|---|
| Id | CompoundIdentifier | 1 | Unique identifier |
| ProductId | Integer | 0..1 | Identifies the participating product to be described. Note that it is optional in order to accommodate systems that do not treat tillage like a product with its own ID. |
| Representation | NumericRepresentation | 1 | How are we going to express the quantity of product involved? |
UnitOfMeasure
| UnitOfMeasure
| 1 | Specific unit of measure used. Please note that the representation itself only specifies the dimension (e.g., mass per unit area), NOT the UoM! |

| OutOfFieldRate | RxRates | 0..1 | 20150925 R. Andres Ferreyra (Unlicensed): This suggests a single-product prescription, and is inconsistent with the multi-product implementation of the RasterGridPrescription and Vector Prescription. This should become a vector if multiple products are to be used. |
