| qudt:latexSymbol | rdf:Property | The symbol is a glyph that is used to represent some concept, typically a unit or a quantity, in a compact form. For example, the symbol for an Ohm is $ohm$. This contrasts with 'unit:abbreviation', which gives a short alphanumeric abbreviation for the unit, 'ohm' for Ohm. | 0 | * | qudt:LatexString | -- | |
| qudt:organizedUnder | rdf:Property | <p>Relates a quantity kind to a broader quantity kind for the purpose of <em>organization and unit applicability only</em> — it does <strong>not</strong> assert commensurability. A sub-property of <code>skos:broader</code> (so it contributes to the concept hierarchy), but unlike <code>qudt:specializationOf</code> it makes no commensurability claim: <code>qudt:organizedUnder</code> groups quantity kinds that share a dimension but are <em>not</em> interchangeable — principally the dimensionless quantity kinds, which are all organised under <code>quantitykind:Dimensionless</code> / <code>quantitykind:DimensionlessRatio</code> without being commensurable with one another. <code>qudt:organizedUnder</code> still contributes to the concept hierarchy (via <code>skos:broader</code>), and the build still validates that it only links quantity kinds of the same dimension, but the applicable-unit computation traverses only <code>qudt:specializationOf</code> — an organizational grouping confers no units on its members. The commensurability test likewise traverses <code>qudt:specializationOf</code> and <code>qudt:exactMatch</code> (never <code>qudt:organizedUnder</code>).</p> | 0 | * | qudt:QuantityKind | -- | |
| qudt:specializationOf | rdf:Property | <p>Relates a quantity kind to a broader quantity kind of which it is a <em>specialization</em>, asserting <strong>commensurability</strong>: the two share a dimension, their values are comparable and addable, and their units are inter-convertible. A sub-property of <code>skos:broader</code>. Commensurability families are the connected components under <code>(qudt:specializationOf | qudt:exactMatch)</code>. Contrast <code>qudt:organizedUnder</code>, which groups quantity kinds without asserting commensurability.</p> | 0 | * | qudt:QuantityKind | -- | |

| 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 | -- | |
