Description

Specifies the unit associated with a metric concept. Example:

  <concept id="area_unit" extends="unit:unit">
    <info>
      <name>
        <value>Area in square kilometers</value>
      </name>
    </info>
    <table ref="area_unit_table"/>
  </concept>

The table contains a single row that contains the property values:

  symbol,symbol_position,unit_text
  km²,END,square kilometers

One can then use this unit in defining a metric concept:

  <concept id="country_area" extends="quantity:magnitude">
    <info>
      <name>
        <value>Country area in square kilometers</value>
      </name>
    </info>
    <attribute id="unit" concept="area_unit"/>
    <table ref="country_area_table"/>
  </concept>
