    dcterms:description """
  <p>The "qudt:id" is an identifier string that uniquely identifies a QUDT concept. 
  The identifier is constructed using a prefix. 
  For example, units are coded using the pattern: "UCCCENNNN", where "CCC" is a numeric code or a category
   and "NNNN" is a digit string for a member element of that category. 
  </p>
  <p>For scaled units there may be an addition field that has the format "QNN" where "NN" is a digit string representing
   an exponent power, and "Q" is a qualifier that indicates with the code "P" that the power is a positive decimal exponent,
   or the code "N" for a negative decimal exponent, or the code "B" for binary positive exponents.
