Introduction

Consider the adjacent recipe for chocolate chip cookies. There is an obvious missing element to this: units of measure. One tablespoon of pure vanilla extract? Teaspoon? Drop? Like cooking, supply chain and field operations quantities are meaningless without knowing units of measure. AgGateway, other agriculture-industry associations, agricultural companies, and standards bodies have addressed units of measure in their standards, guidelines, and products. This page provides a starting point for implementers to understand how units of measure are used in agriculture.

Chocolate Chip Cookies

1/2 __ unsalted butter
3/4 __ packed dark brown sugar
3/4 __ sugar
2 large eggs
1 __ pure vanilla extract
1 __ semisweet chocolate chips, or chunks
2 1/4 __ all-purpose flour
3/4 __ baking soda
1 __ fine salt

Units of Measure in AgGateway Open Standards

AgGateway Open Standards specifies use of UN/CEFACT Rec 20.

Consider the following AgGateway Open Standards XML document:

Measurement XML
<?xml version="1.0" encoding="UTF-8"?>
<Measurement
	xmlns="urn:cidx:names:specification:ces:schema:all:5:3">
	<MeasurementValue>50</MeasurementValue>
	<UnitOfMeasureCode Domain="UN-Rec-20">BG</UnitOfMeasureCode>
</Measurement>

Explain how this works.

Units of Measure in AGIIS

 AgGateway's AGIIS service supports UN/CEFACT Rec-20 and ANSI ASC X12 unit of measure codes. The Excel file below...<explain>

Units of Measure in AgXML

Consider the following AgXML XML document:

<?xml version="1.0" encoding="UTF-8"?>
<QualityFactorValue
	xmlns="urn:www.agxml.org:schemas:all:4:0"
	unitOfMeasure="GL">1000.00</QualityFactorValue>

Line 1 simply indicates that the content is XML. The remaining lines contain a single element, QualityFactorValue with an attribute unitOfMeasure. Line 3 specifies the default namespace, to which the element belongs.
