| qudt:abbreviation | rdf:Property | <p>An abbreviation for a unit is a short ASCII string that is used in place of the full name for the unit in contexts where non-ASCII characters would be problematic, or where using the abbreviation will enhance readability. When a power of abase unit needs to be expressed, such as squares this can be done using abbreviations rather than symbols. For example, <em>sq ft</em> means <em>square foot</em>, and <em>cu ft</em> means <em>cubic foot</em>. </p> | 0 | 1 | xsd:string | -- | |

| qudt:id | rdf:Property | <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. </p> | 0 | 1 | xsd:string | -- | |
